Seeking Member Support for Biogas Tax Credit Bill - American Biogas Council

The American Biogas Council is encouraging its members to help support one of its highest legislative priorities—a bill that would create an investment tax credit for biogas.


Although not yet introduced, the bill is being considered by Rep. Ron Kind, D-Wis. If passed, it would grant qualifying biogas (anaerobic digestion) projects parity with other renewable energy projects that already qualify for a 30 percent investment tax credit under Section 48 of the Internal Revenue Service Code of 1986.


The bill defines qualified biogas property as comprising of a system that uses anaerobic digesters or other biological, chemical, thermal or mechanical processes (alone or in combination) to convert biomass into a gas, which consists of not less than 52 percent methane, and captures the gas for use as a fuel.


Besides the tax credit, the bill would also require the government to enter into an agreement with the National Renewable Energy Laboratory to undertake a study of biogas. The agreement would require NREL to supply a written report to Congress within two years after the date of the enactment of the bill to address multiple issues, such as the quality of biogas and a comparison of biogas to natural gas and the identification of any components of biogas that make it unsuitable for injection into existing natural gas pipelines. Other issues the study would address include methods for obtaining the highest energy content in biogas, including the use of codigestion and identifying the optimal feed mixture, and recommendations for the expansion of biogas production, including an analysis of the extent to which increasing the methane content of biogas would result in its greater use and an analysis of how the expanded use of biogas could help meet the growing energy needs of the U.S.


Patrick Serfass, excutive director of the ABC, said one type of project that would benefit from the tax credit would be one that injects renewable natural gas into the gas pipeline, or uses the biogas to power cars and heavy duty vehicles.  "For example, this tax credit will help a dairy farmer who makes biogas from cow manure and then uses it to heat the buildings and power the trucks that deliver the milk," he said. "In another example, it would help a facility that takes food waste from area restaurants and grocery stores, turns their trash into biogas and then injects the renewable natural gas into the pipeline to be used by any natural gas customers."


Serfass said the idea of turning organic waste into usable, renewable biogas, is just taking off in the U.S. and it's something that should be encouraged. "Whether you've got rural farm waste, urban food waste or the sludge filtered out of wastewater, a tax incentive like this will create new jobs with every new project constructed that will put people to work turning garbage into green energy," he added.


The ABC is requesting that members write to their congressional representatives to make them aware of the legislation and urge them to support it. To view a copy of the bill, click here.

Biogas Trike Fueled by Sewage Completes its Journey Across Japan

Enter the Neo. Part motorcycle and part toilet, it runs on eco-friendly biogas produced from sewage — and recently completed a journey of more than 1,000 km across Japan.


The three-wheeled vehicle, developed by Japanese toilet maker Toto, features a toilet for a seat and has a giant roll of toilet paper mounted on the back that flutters in the breeze as the bike cruises along.




>
>


But there are no plans to put the bike on sale. Toto intends to put it on display.


The biogas used as fuel for the Neo is produced from a combination of household sewage and livestock waste, broken down and fermented, company spokesman Kenji Fujita said.


“Although the seat of the bike is indeed a toilet, it is not for actual use. The fuel is eco-friendly biogas, stored in the tanks on the back,” he said.


“It’s a surprisingly nice way to travel.”


The 837 lb motorcycle can run for a total of 300 km and reach speeds of up to 70 km an hour.


Ichie Tanaka, one of six people who rode the Neo across Japan during the three-week, 1,400 km tour to promote biofuels, said she was relieved the journey was over.


“At first when I saw the bike, I was taken aback. But after riding it, I found it quite interesting,” the 28-year-old said.


“It doesn’t hurt at all and is actually quite comfortable to sit on.”

Eco-Tec Biogas Purification Systems Commissioned and Delivering Power

 

Two state-of-the-art waste processing facilities in Lancashire, England, report quick start-up times and strong levels of performance by newly installed BgPur™ biogas purification systems.




>
>


(The video is not directly relatede to the article - but we thought our readers would find it interesting.)


Designed and manufactured by Canadian-based Eco-Tec Inc., the BgPur units have begun purifying biogas produced at waste treatment facilities in Lancashire, by removing corrosive levels of hydrogen sulfide (H2S); in turn, recovering the gas for use in power generation. The first BgPur began operation in July 2011 at the Thornton Waste Facility and the second in November 2011 at the Leyland Waste Facility. Both were designed by international engineering and project-management company AMEC, and are run by waste management and recycling organization Global Renewables.


While the systems are set up to clean H2S at 99% efficiency per site, they have recorded levels beyond 99% and continue to perform consistently since the start ups. "We're happy with the system's performance. In some instances, it has gone beyond the capabilities specified and was also one of the easiest start ups we've experienced so far," said an AMEC representative.


The BgPur systems are playing an essential part in Global Renewables' unique waste-treatment process known as ‘UR-3R' (Urban Resource - Reduce, Recover, Recycle), made up of a combination of some of the world's leading environmental technologies. Through the process, the facilities will treat over 300,000 tonnes per annum of Lancahsire County's household waste while extracting the maximum amount of recyclables from the waste stream and turning the environmentally damaging organic fraction into a high-quality type of compost product called Organic Growth Medium (OGM).


As these organic wastes are digested, Eco-Tec's BgPur purifies the biogas produced through patented, high efficiency gas-liquid contactors. The contactors process 1,100 m3/hr sulphur with a concentration of 5,000 ppmv (parts per million volume) of H2S per site, purifying it to consist of less than 50 ppmv of H2S. In turn, the recovered gas is used as fuel to generate electricity for the parasitic demands of the sites. The net result is 100% recycling, reducing the waste to the landfill by 70%, and reducing the carbon dioxide emission by 1.5 tonnes per tonne of solid waste collected.


"Eco-Tec is proud to play a part in such an innovative, meaningful waste-treatment process. And we're glad to be able to add real value to the market by providing technology that not only lowers our clients' operating costs but is also solving greenhouse gas issues at the same time," says Carmine Fontana, Eco-Tec vice-president, Gas Processing.

Holton: Bernard Matthews plans £4m biogas plant - East Anglian Daily Times

Rob Mears, UK managing director of Bernard Matthews Foods

Friday, November 11, 2011 - 6:00 AM


TURKEY giant Bernard Matthews has unveiled a £4million project to convert waste into biogas at its Suffolk factory which it hopes will save energy and reduce the number of lorries going into the facility.


The firm has teamed up with Glendale Power for a renewable power project at the site in Holton, near Halesworth, which it hopes will supply 13% of its electricity and 10% of its heat.


A planning application is expected to be submitted to Waveney District Council in the coming weeks, and if approved the firm hopes the facility, which will be funded by venture capital, will be up and running by April 2013 with work likely to start next year.


The proposal would see the construction of an anaerobic digestion facility which would treat 28,000 tonnes of liquid waste including blood fluids and fat and see it converted into gas which can be turned into electricity.


The digester will be connected, by pipeline, to the existing on site effluent treatment system, and the liquid waste will then be converted into a methane rich gas, which will be piped back into the factory to power an engine connected to a generator.


Electricity produced will be fed into the factory power grid and heat recovered from the cooling system and exhaust will be used to heat water.


Spent “fuel”, which will be largely water, will be returned to the on site effluent treatment system to be cleaned up and discharged.


Richard Smithgate, group procurement director at Bernard Matthews Foods, said the facility would consist of three towers which would be integrated into the existing factory.


“This ensures that we treat our own waste rather than have it treated by a third party,” he said. “We want to become more self-sufficient and all energy will be used on the site and none of it will be exported.”


Around 60% of the factories traffic is linked associated with waste and Mr Smithgate said the proposal would removed more than 1,200 lorry trips in and out of the site.


He also said the process involved would not be open to the air and that would mean no odours would be emitted from the facility.


“It will be like a soup,” he added. “It will sit in the cylinders for about 35 days and that process will generate the gas to produce the electricity.


“We hope to get a positive reaction because we are taking 1,200 vehicles off the road and we hope that will enhance the community.


Rob Mears, UK managing director at Bernard Matthews Foods, said: “This is an important development for Bernard Matthews and the local community.


“It will not only reduce our carbon footprint and help create a sustainable, constant, environmentally-friendly source of power for the factory, but it will also provide significant environmental benefits to the local community and help strengthen our long term competitive position for the site.”

Carr Farm £2.5M Green Energy Project Reaches Milestone, as AD Plant Construction Progresses


Image: Courtesy Farmgen

With all the worldwide business news being so bleak at the moment it is easy to forget that the Anaerobic Digestion Industry is still forging ahead with new projects.

So, it is good to be able to publicise a ground-breaking £2.5M renewable energy project, which is it's originator's Farmgen are claiming is changing the face of UK farming, has reached a major milestone.

After the completion of preliminary work on-site and the construction of service roads and clamps to hold material to feed the plant, building is now well progressed on the two large tanks, which will form the centre of interest in this biogas scheme.

Farmgen is the green energy specialist behind the farm-based Anaerobic Digestion (AD) plant at Warton, near Preston which they are describing as "revolutionary". At the Anaerobic Digestion News blog we are not so convinced that the calim to it being revolutionary can be sustained in reality.

Certainly, the site at Carr Farm is going to be "revolutionary" to farmer Jonathan Rigby who is moving out of dairy farming, which his family has been involved in for generations, into what is baing called ‘energy farming’.

We are also able to report that the construction of these two AD tanks is part of a push by Farmgen which will lead to a £30 million investment in what we are sure must be the biggest ‘energy farming’ expansion programme yet, in Britain.

Farmgen says that UK farmers of the future will set to make more money, more easily out of ‘energy farming’, than traditional dairy, animal husbandry and arable farming.

However, as a consumer it is surprising to read that farmers are receiving falling prices for farm products, whiel watching the weeekly food bil rise as much as it has done this year. However, they also state that farmers are being increasingly squeezed by the supermarket giants, and that would appear to be entirely credible as the bog chains consolidate their market share and enter into another supermarket price war to do so.

We are sure that more and more farmers are realising there’s a more sustainable future in helping to avoid Britain’s looming energy crisis and supporting the move towards a low carbon economy.

There is no doubt a power ‘generation gap’ which most likely will open-up over the next 5-10 years, as the UK’s ageing fleet of fossil-fuel-burning power plants come offline to meet tough new EU emissions targets.

At this blog site we, also agree that:
“Renewables and other sources of green energy will play a critical role in providing the country’s power supplies over the next decade,”
 explained Farmgen’s chief operating officer, Ed Cattigan.
“As the country moves over to green energy, as part of the move to a low carbon economy, there is a strong opportunity for many farmers in the UK to create a sustainable and stronger future for themselves by switching to ‘energy farming’."
Go and take a look at the much longer article at http://www.farmgen.co.uk/news13.htm where you will also find out about the involvement of other UK and international companies involved in this biogas project, including:

  • Kirk Environmental, a specialist company manufacturing AD tanks
  • Edina, the leading renewable power generation specialists who will supply the plant’s generating equipment
  • Engineering specialist Agrilek, from Barrow-in-Furness, Cumbria, responsible for connecting the plant to the national grid
  • Inenco, based in Lytham St Annes, Lancs, to trade the energy produced at Carr Farm
  • Green Energy Farmers Ltd, who will supply the crops to the Anaerobic Digestion Plant
  • Eimco Water Technologies Ltd, based in Tonbridge, Kent who act as the water treatment experts

We understand that Farmgen offer to run and manage a farm’s AD business, while providing a guaranteed income level for farmers for up to 10 years. The company says that they can also source finance and offer a joint venture approach to farmers interested in a possible AD project.

First Biogas Plant for Electricity and Heat Generation by Enovos Luxembourg SA ... - MarketWatch (press release)

STRASSEN, Luxembourg, October 18, 2011 /PRNewswire via COMTEX/ -- Enovos Luxembourg is successfully expanding its activities in the field of renewable energy and takes a share in the Biopower Tongeren N.V.




>
>


100% owned by Enovos International S.A., Enovos Luxembourg is a part of the Enovos-International-group.


On Monday, 17 October 2011 at the industrial estate "Tongeren Oost" (Tongeren, Belgium), Enovos Luxembourg S.A. and its project partners NPG Energy N.V. and Pholpa BVBA celebrated the first stone ceremony of the largest biogas plant in Limburg. In presence of a.o. Jean Lucius, CEO Enovos Luxembourg S.A. and the Mayor of the City of Tongeren, Patrick Dewael, a tree was planted to symbolise that this biogas plant will be 100% CO2 neutral.


In August 2011, Enovos Luxembourg S.A. signed the contracts to acquire a 24.9% stake in the biogas plant. For Enovos Luxembourg, this represents the first investment in renewable energy in Belgium.


Located in a predominantly agricultural area, the biogas plant will mainly ferment corn that is grown in close cooperation with local farmers within a 15 km radius. The resulting environmentally friendly biogas is converted into electricity via a motor and is then fed into the local power grid. The heat resulting from the process is used to dry the fermentation substrates. These substrates are returned to the fields as low-odour, high-quality fertilisers, thus producing a closed cycle.


"With a capacity of approximately 3 MW, the amount of electricity generated corresponds to the annual consumption of 6,500 households and an annual CO2 reduction of 10,000 tonnes, thus achieving an important step towards further expanding renewable energies," says Daniel Christnach, Head of Renewable Energies & Cogeneration at Enovos Luxembourg. In cooperation with the project partners, the plant's capacity can optionally be subsequently expanded to 5.6 MW. The building licence for this already exists.


Jean Lucius, CEO Enovos Luxembourg highlights: "The participation in the Biopower Tongeren N.V. emphasises Enovos' consistent commitment to the field of renewable energy and we are pleased that with this first project we were able to assert this message on the Belgium market."


The plant start-up will take place in April 2012.


The project developers NPG Energy N.V. and Pholpa BVBA are involved as additional partners in the project company, Biopower Tongeren N.V., each with 47.6% and 27.5% respectively.


As energy supplier on the Luxembourg, German, French and - since 2011 - Belgian energy market, Enovos Luxembourg's mission consists of generating electricity, natural gas and renewable energy for municipal providers, industries and private households and in delivering it to them.


They are subordinate to Enovos International S.A., which is an operative holding company with its headquarters in the Grand Duchy of Luxembourg. In addition to supplying energy, the parent company also acts as an umbrella for the management of the grid operator, Creos Luxembourg S.A.


Expressed in numbers, the Enovos-International-group currently consists of more than 1,300 employees, more than 280,000 points of delivery, over 8,700 km of electric lines and more than 3,600 km of gas pipelines.


In addition to its traditional core business, the company is expanding its activities mostly in the field of renewable energy.


25.44% of Enovos International S.A. belongs to Luxembourg State, 10.01% belongs to the state-owned investment bank SNCI and 8.00% belongs to the City of Luxembourg. ArcelorMittal owns 23.48%, RWE owns 18.36%, E.ON has 10.00% and Electrabel holds 4.71%.

Flotech vows to treble biogas revenues - Stuff.co.nz

Flotech, the biogas equipment developer, says soaring demand for renewable energy from Asia, Europe and North America will likely see its revenues triple to $300 million as early as 2015.




>
>


The Auckland-based company develops proprietary processing technologies that converts decomposing organic matter such as fish waste and cow dung into a biogas. It plans to achieve the revenue boost by extending its dominant position in the biogas conversion market, predominantly through its Greenlane Biogas subsidiary.


Greenlane commands about 32 per cent of the biogas upgrading sector worldwide, the company said.


"We are one of the very few companies to have emerged with proven technologies for biomethane and our plan is to extend dominance of that sector," said group managing director Steve Broadbent. "Our reputation is now such that no serious developer would contemplate a biomethane project without at least including Greenlane for consideration on the supplier list."


Braodbent is the majority shareholder of the privately-held company with a 40 per cent stake. The company didn't release any actual financial figures, but it said the growth is due to a four-year transformation process in which it changed from a "projects-driven, compressor dominated business" into a worldwide marketing vehicle for the Greenlane products.


In spite of the costs of the additional costs of the transformation, which exceeded budget and ran over time, Broadbent said the expansion "is coming to fruition".


To date the company says it has sold more than 50 Greenlane Biogas upgrading systems, which produce biofuels for vehicle fleets, communities, power grids and pipeline gas.


Flotech joins a cadre of New Zealand companies which have pioneered green technologies overseas, most notably Lanzatech, the as-yet-to-break-even company which develops industrial pollution reduction technologies.


Both companies have won numerous awards in recent years, and have been the recipients of major government innovation funding.

Proposed biogas plant at West Lexham could create 30 jobs - Norfolk Eastern Daily Press

The company behind plans for a new biogas plant at West Lexham, near Swaffham, says it will reduce the amount of waste going to landfill.

By DAISY WALLAGE Thursday, October 27, 2011 


A proposed biogas energy plant near Swaffham could create up to 30 jobs.


West Lexham Biogas Limited will begin consulting on its plans to build a waste recycling plant and anaerobic digester (AD) at a disused quarry near the village later this month.


The plant will generate green electricity using waste from the food and drinks industry, reducing the amount of rubbish going to land fill and also producing organic fertiliser.


Residents and local councils are being invited to an exhibition about the project in Castle Acre on November 10 and a planning application is expected to be submitted in December.




>
>


The company is being driven by Teun Smits, who has experience in developing and operating AD plants in Holland, and by Qualiflex Biproduct Solutions Limited (qbs), a Bury St Edmunds-based company specialising in the sustainable transfer of waste products.


A spokesman said: “As a country we landfill thousands of tonnes of waste food and drink. This project should be the first of a number of these units we will develop to process this waste across the country and we are delighted to have found a site which meets our East Anglian needs.


“The site has a good road network and is in a hidden part of the landscape away from residential properties. This plant should produce approximately 30 new jobs for the area and the construction work will also provide employment opportunities.”


Gases produced during the digestion of waste are pumped into gas engines to create electricity while the resulting “digestate” will be made available to local farms for use as an organic fertilizer.


Landowner, Niels Olesen, added: “As someone who is passionate about alternative energy production, I am delighted to be working with such a knowledgeable company. “The infrastructure is here and the former gravel working is a logical brownfield site for a use such as this. We hope to gain local support for this exciting project”.


The exhibition will be held at Castle Acre Village Hall, in Pye’s Lane, from 4pm to 7pm on November 10 and there will be the chance to answer questions.

Anaerobic Digestion Plant Powers Northern Ireland Village

Cow poo powers village

London, United Kingdom - Cow poo and grass are the main ingredients for cooking up new high efficiency power  
 
The first energy plant of its kind in 20 years demonstrates how natural processes can power a business and a village with renewable energy.  A farm near Ardstraw in Northern Ireland uses technology that allows the production of heat and power from animal waste and vegetation.  Fuelled by organic matter produced on the farm, this pioneering power plant is also one of the most environmentally friendly of its kind.  The plant is very efficient and wastes very little compared to other energy companies.  Normally, central power plants pump more than 50% of the energy into the air while turbines waste 75% of the wind’s energy.  Now, run on muck, the cow power plant has an energy efficiency of 86%, wasting only 14%, which a huge step toward a sustainable Northern Ireland.  
 
The Greenhill Dairy Farm Biogas plant is the first plant in Northern Ireland in 20 years to provide sustainable heat and power for homes and businesses.  The power station mimics a cow stomach and cooks animal waste at 40°C (104°F) to produce methane gas.  The gas is then piped into two engines that drive generators while hot water is also produced for drying plant waste, called ‘digestate,’ and to pasteurise milk.  This use of waste to produce valuable energy shows how rural areas and agriculture can function sustainably.  Power derived from cow dung and grass silage cuts power prices for all consumers and decreases agriculture’s carbon footprint.  Additionally, the unit will reduce Northern Ireland’s reliance on fossil fuels and prevent volatile energy prices whilst bringing new jobs to this rural area.

Alfagy - Anaerobic digestion

The 700 acre Greenhill farm delivers grass and animal waste from some 600 cows to fuel the plant.  After the process of extracting methane from the manure and grass, farmers will use the residual waste, called 'digestate', as a powerful fertiliser to grow animal feed.  Capturing the value from this natural cycle is essential to enable local farmers to compete internationally.  Looking like a giant muffin, the plant produces 430 kilowatts of electricity per hour - enough to supply some 430 homes with electricity.  
 
A farm AD plant has far less visual impact and noise pollution than wind turbines and delivers far more socio-economic benefits in rural areas.  The farmer earns money from his waste, the plant reduces energy and fertiliser costs which stabilises his income.  AD plants are also the number one job-creating renewable technology.  Alfagy’s research shows that widely adopted biogas plants create far more long term jobs than any other renewable technology and more money for the Government.  “It is astonishing that more financial support isn’t directed at biogas power plants as they create 8 times more value than other renewable technologies such as wind turbines,” comments Peter Kindt, the Alfagy chairman. 

World’s most efficient energy 
  
Alfagy was selected by the developer for the project as the Combined Heat and Power (CHP) and gas conditioning supplier after a competition against leading manufacturers such as GE Energy, MWM and MAN.  The project faced challenges in getting funding from a bank during the financial crisis that is still raging internationally.  However, Alfagy’s high level of quality and service convinced the bank to grant a development loan.  This is considered something of an accomplishment in the current climate according to Peter Kindt.  "Given the current credit crunch, this project is an important demonstration of a sustainable energy future", said Peter Kindt. 

"The deciding factor for the finance of the project was our plant’s world beating efficiency that produced £1.8 million more revenue than the competition.  Our payback is simply the fastest in the market,” adds Peter Kindt. 

The Ardstraw power plant will be the 52nd biogas power plant in the UK and only the 2nd in Northern Ireland.  More farmers in Northern Ireland are now considering similar projects. (See also http://anaerobic-digestion.com )

Jobs Boost as Waste Plants Open - BBC News

5 October 2011 Last updated at 12:31 


The anaerobic digestion plant in Cumbernauld will process 60,000 tonnes of food waste a year Waste Management group Shanks has opened two major recycling and recovery facilities in the west of Scotland, creating 40 jobs.



An anaerobic digestion (AD) plant in Cumbernauld will process 60,000 tonnes of food waste a year, generating enough power for more than 3,000 homes.




>
>


A materials recycling facility (MRF) in Blochairn will process 150,000 tonnes of waste and recyclables a year.


Shanks said about £20m had been invested in the two plants.


The AD plant, which is a joint venture with Cumbernauld-based Energen Biogas, will treat organic waste from local authorities and food waste producers, maximising the amount of recyclable material recovered from food waste.


The MRF plant will serve municipal customers, such as North Lanarkshire and East Dunbartonshire councils, as well as commercial and industrial clients.


It has been designed to achieve a 95% recovery rate from resources such as cardboard, paper, aluminium, glass, wood and metals.


The remaining waste will be converted into solid recovered fuel (SRF) for heat and power.


A total of 39 jobs have been created across the two sites - 33 at Blochairn and six in Cumbernauld.

'Zero waste' goal

Shanks UK managing director Ian Goodfellow said: "At Shanks, we are continually investing in recycling and recovery technology to reduce the amount of waste sent to landfill and incineration.


"Scotland's vision where all waste is seen as a resource is one we are firmly aligned with and we are very pleased that with the opening of these new plants we can contribute to making a zero-waste Scotland a reality."


Environment Secretary Richard Lochhead said Shanks' new facilities demonstrated that sending rubbish to landfill was "increasingly becoming a thing of the past".


He added: "Minimising the amount of waste we create in the first place is the best course of action, but from the waste we do produce we need to recycle and recover as much value as possible."


Energen Biogas operations director Robert Etherson said AD plants provided "a fantastic opportunity" to grow the renewables industry in Scotland and improve resource efficiency.


He added: "I believe we really are at the forefront of a revolution in sustainable waste management in Scotland where AD technology will play an increasingly large role."


Both plants have started to receive waste from customers and Shanks expects Cumbernauld to be operating at 100% capacity in a year's time.


Customers include Glasgow Airport, Strathclyde University and NHS Greater Glasgow & Clyde.


Shanks is an international waste management group with more than 4,000 employees across its operations in Belgium, Canada, Netherlands and the UK.

Landfill Gas to Power Wewoka Brick Company's Kilns - NewsOK.com

WEWOKA — Most businesses probably wouldn't want to have a landfill next door, but it is working out well for Commercial Brick Corp.


The Wewoka Biogas Project was designed to reduce greenhouse gas emissions from WCA Waste Corp.'s Sooner Landfill in Wewoka, while providing cheaper fuel to the nearby Commercial Brick Corp. plant. The annual reduction of greenhouse gases attributable to the project are about the same as:

>


Greenhouse gas emissions from nearly 6,800 passenger vehicles


• Carbon dioxide emissions from consuming more than 82,000 barrels of oil


• Carbon sequestered annually by nearly 7,600 acres of pine or fir forests


Source: U.S. Environmental Protection Agency's


landfill methane outreach program


The family-owned brickmaker is getting biogas from the WCA Waste Corp. landfill about a quarter mile north of its plant.


The Wewoka Biogas Project, which is providing methane to one of Commercial's four kilns, was dedicated Friday by a host of officials from the companies involved in making it happen.


William Brinker, operations manager of project developer Enerdyne Power Systems Inc., said the project grew out of a WCA initiative to reduce its greenhouse gas emissions. That meshed with Commercial's quest to find a way to reduce its energy costs.


“It just makes economic sense because we're displacing other fossil fuels,” Brinker said.


Companies like eBay, Designtex and Green Mountain Coffee Roasters helped finance the project by buying carbon offsets.


Brinker said decomposing trash in the Sooner Landfill creates methane, the main component in natural gas.


It is collected by 14 vertical wells drilled into the landfill.


The gas is processed at an adjacent blower station to remove excess water and then sent over to the brick plant.


Commercial President Bob Hartsock said the company always is looking for ways to save money on fuel.


“This just made perfect sense,” he said.


Hartsock's company makes about 156 million bricks a year, running its natural gas-fired kilns nonstop, 24 hours a day.


Hartsock said companies often try to build brick plants near landfills to take advantage of available biogas, but Commercial had the luxury of having a landfill built about a quarter mile from its plant.


“All we had to do was retrofit our burners to accept the methane gas,” he said.


Hartsock said it is too soon to know how much the biogas project will save in fuel costs, but the arrangement will allow Commercial to remain competitive in a tough environment.


The deal means gas from the landfill always will be cheaper than natural gas.


“That's where it's really a home run for you,” he said.


Hartsock said he is looking forward to drawing more methane from the landfill over time.


“The more waste they get out there the more it will generate,” Hartsock said.

Konzen Clean Energy Gets Biogas Plant Contract Worth US$2.5 Million - Bernama

October 28, 2011 15:07 PM


Konzen Clean Energy Gets Biogas Plant Contract Worth US$2.5 Million




>
>


KUALA LUMPUR, Oct 28 (Bernama) -- Konzen Clean Energy Sdn Bhd (KCE) has been awarded a US$2.5 million (US$1=RM3.03) contract by Indonesia's PT Paramitra Internusa Pratama to set up a biogas plant at its Belian Estate in West Kalimantan by July 2012.


KCE is a BioNexus-status firm facilitated by Malaysian Biotechnology Corp Sdn Bhd (BiotechCorp) while PT Paramitra is a unit of PT SMART Tbk Agribusiness & Food.


In a statement Friday, BiotechCorp's chief executive officer, Datuk Dr Mohd Nazlee Kamal, said the initiative by KCE delivered on the agenda for Phase II of the National Biotechnology Policy -- commercialisation of biotechnology.


"It also reflects the maturity and strength of our local biotech firms and their competitiveness in embarking on strategic partnerships for the robust development of the industry," he said.


Under the agreement, KCE will provide the design, supply, engineering, installation, commissioning and project management of the effluent treatment plant, complete with anaerobic digester tanks and state-of-the-art process control system of the biogas plant.


The plant will have sophisticated monitoring equipment that facilitates comprehensive data logging, useful for plant improvements and future research and development work under the ongoing developmental activities of KCE.


Biotechcorp said the technology transfer from KCE for the development of the biogas plants plant would therefore be relevant far beyond the project itself and would be appreciated by industry in the future.


It said as an alternative to fossil fuels, PT SMART planned to use biogas at this plant produced from its palm oil mill effluent to generate electricity for its palm oil mills, the statement said.


"The surplus supply of the electricity would be directed to the community," it said.

Biogas plant makes the most of fuel from waste - FarmersWeekly

Biogas plant makes the most of fuel from waste - 9/21/2011 - Farmers Weekly
Neil Gemmell, who farms at Clayton Hall Farm near Wakefield, has installed a 400kW anaerobic digestion plant, to process 6,000t of feedstock a year. Although the plant would be viable with energy crops from the farm, in energy terms, some 80% of the feedstock comes from food waste.
Video shows plant used elsewhere by Biogas Nord

> >
The large digester has a capacity of 2,800cu m, which is required for the long retention times that are a feature of the system supplied by Biogas Nord.
"The system is designed to run on less than 4kg of solid material per cubic metre per day," explains Biogas Nord's UK representative Owen Yeatman.
"Traditional British digesters are smaller, but the economics are driven by gate fees. We want to extract all the energy from whatever comes in. For example, with maize we would expect 90-95% breakdown of the material."
One advantage of the large digester is the amount of gas storage it provides, something that other installations use secondary digesters or separate gas stores to achieve.
To handle food waste, the plant needs to comply with animal by-products (ABP) legislation, which includes a requirement for an enclosed reception area. At Clayton Hall a redundant grain store was used, meaning that extra capital was required to comply with this aspect of the rules.
From the reception building, the solid material is augured into the digester where agitators keep the mixture moving for up to 60 days. A heating system incorporated inside the concrete walls maintains the temperature at 40-42C. Once the gas has been extracted, the digestate is sent to a pasteuriser, which is a key difference from most on-farm plants. The material is pumped through a macerator to ensure it is small enough to comply with the ABP rules and then pasteurised in batches at 72C for one hour.
In terms of cost, Mr Yeatman reckons that the need for pasteurisation increased the overall capital cost of the plant by as much as 10%. "There is also a significant operating cost in terms of monitoring and meeting statutory requirements," he adds.
The pasteurised digestate is currently stored in a lagoon, although the farm plans to install a separator to separate the liquid and solid fractions, which can then be marketed under the PAS110 standard for quality digestate.
Mr Gemmell is very happy with the system, but he warns other farmers thinking about developing a waste-fed biogas plant to think carefully. "It certainly comes with a whole raft of extra things on top," he says.
While the costs of the plant are confidential, Mr Yeatman says that a typical 500kW plant using farm-based inputs would be around £1.6m, excluding digestate storage. He estimates that once adding compliance with ABP regulations has been offset against the need not to construct a silage clamp for feedstock storage, the additional cost for a food waste plant of the same size would be around £200,000. Gate fees and gas output should increase the margins on the plant, but at higher management, regulatory and capital costs compared with plants based on farm inputs.

Northern Ireland Opens New biogas CHP plant - Cogeneration & On-Site Power Production Magazine

A farm near Ardstraw in Northern Ireland is converting organic matter into biogas to provide sustainable heat and power on-site, as well as for local homes and businesses.


The 700-acre Greenhill farm biogas plant plant is only the second such plant in Northern Ireland. It works by ‘cooking’ animal waste from 600 cows at 40°C to produce methane gas.

The gas is then piped into two engines that drive generators to produce electricity. Hot water is also produced and is used to dry the plant’s residual, as well to pasteurise milk.


According to Alfagy, which supplied the biogas CHP, it has an energy efficiency of 86%, and represents a significant step toward in achieving an energy sustainable Northern Ireland.




>
>


The plant produces 430 kWh of power, which is sufficient to supply around 430 homes.


After the process of extracting methane from the manure and vegetation, farmers use the residual waste as a fertiliser to grow animal feed.


Alfagy says the project faced challenges in attracting funding from banks during the financial crisis.


“It is astonishing that more financial support isn’t directed at biogas power plants as they create eight times more value than other renewable technologies such as wind turbines,” says Peter Kindt, Alfagy’s chairman.

Stove that works on biogas as well as LPG - IBNLive.com

THIRUVANANTHAPURAM: K T Ajayakumar keeps on improving what he knows best, ie experimenting with gadgets and appliances. Ajayan, who runs the Thankam Gas Service Centre at Aramkallu, Vazhayila, has now come up with a new gas stove which can be lit using both LPG and biogas.
 “For this, I have not changed the structure of the LPG gas stove. Only that it has a special air hole arrangement so that it functions on biogas as well. It has two knobs- one for LPG and the other for biogas,” says Ajayan.

> >
(The video is not related to the artcle.)
A half-inch hole is made at the end of the stove burner and the biogas pipe is connected from the valve to the burner. While LPG needs an air hole, it is not needed for biogas. Also, the stove comes with a separate burner top - with 4 mm holes- for the biogas. No change has been made in the case of LPG pipe.
“I consider this as a great achievement. It would be handy in the case of households which have space constraints,” Ajayan says. And he is ready to make the stove on demand. “They need to shell out just ` 460 for the same,” he says.
This highly enthusiastic 33-year-old has made numerous inventions over the last few years. In fact, this stove is his sixth invention. He had started off with a granite stove, then came up with a bio-heater, then a high pressure stove which saves gas. He even developed a system which would avert train mishaps. “Whenever I get time, I experiment with whatever I come across,” says Ajayan, who has studied till Class X.

First U.S. Dry Fermentation Biodigester Produces Renewable Energy at UW-Oshkosh

The first anaerobic dry fermentation biodigester in the western hemisphere is up and running at the University of Wisconsin Oshkosh. The alternative power system has been producing clean, renewable electricity from plant and food waste to supply electricity and heat for the university campus since Oct. 3.

University staff and students involved with the development of the power system had been stockpiling agricultural plant and food waste as feedstock in airless chambers and feeding it into the dry anaerobic biodigester since last summer in anticipation of bringing it online.
Anaerobic digestion is a process in which microorganisms break down biodegradable material in the absence of oxygen. As part of an integrated waste management system, anaerobic digestion reduces the emission of methane gas, CO2, and “non-methane organic compounds” or NMOCs into the atmosphere.  Anaerobic digestion is also used as a renewable energy source since the process produces a methane and carbon dioxide rich biogas suitable for energy production.


As the name indicates, ‘dry,’ as opposed to ‘wet,’ anaerobic digesters break down dry organic materials with moisture content of less than 75%, such as agricultural waste and plant material traditionally left over after harvesting a crop.

On Oct. 3, the University of Wisconsin Oshkosh team decided they had enough biogas to start-up energy production, so they turned on the plant’s gas turbine engines. The biogas from the biodigester drives the turbines, which are expected to generate enough electricity in the start-up phase to meet 5% of the university’s electricity and heating needs.
Besides producing clean, renewable energy from agricultural and food waste – corn stalks, husks, leaves, and discarded food – the bio-energy plant is serving as an ideal site for experiential learning, particularly for biology and environmental students.


Proposed plans call for revenue from the plant to flow into student scholarships, campus laboratory upgrades and expansion, and the creation of a rural community development innovation center.

Biogas live at Weybridge Waitrose - Surrey Comet

5:17pm Thursday 15th September 2011

A recycling system to convert food waste into biofuel has gone live at a Weybridge supermarket.




>
>


Waitrose in Weybridge High Street now has food not fit for sale taken to an anaerobic digestion plant and turned into organic fertiliser, or biogas which is converted in to electricity.


It means food that is out of date or damaged is put back in to the system rather than just thrown away.


As a result the store has halved the amount of rubbish it sends to landfill.


Waitrose target is for 150 stores to process waste in this way.


Weybridge branch manager David Coleman said: “As the first national food retailer to fully sign up to this food waste recycling scheme, Waitrose is leading the way in taking steps to reduce our carbon footprint.”

Sewage Sludge Reuse: Come On OFWAT the Time for an Open Market is Now


By Steve Last: Renewable Energy News

Beckton Sewage Works, London
We know that until quite recently what to do with sewage sludge was always a challenge for society. After all until the 1970's in the UK most conurbations were simply throwing it into the sea by the shipload. A disposal method which frankly seems cavalier in the extreme now, and would never be countenanced today, but only finally ceased in the late 1990s.

We now that it was a good move when the water acts of 20 years ago were passed it was good move to delegate sewage sludge disposal to the water industry and let the rest of us forget about it.

We know that the privatised UK Water Industry in its turn responded to that regulatory direction and developed a worthy system of dealing with sludge generated by sewage treatment operations, beginning initially with 'disposal' to local farmland and evolving into 'agricultural recycling' helped along by successive regulations defining treatment criteria and requiring control of added nutrients and contaminants.

However, the practical ability to do this depends heavily upon the quantity and quality of the sludge applied matching the needs of the economically accessible agricultural land such that many larger industrial connurbations have had to limit this practise. First landfill was used, but that option was largely closed by the EU landfill directive, which led to incineration as the most applicable solution.

But, all that has now changed with rising oil and coal prices. Like it or not renewable energy is here to stay, and for sludge and until something better comes along, that means Anaerobic Digestion.

And, a little publicised revolution is underway, in which the huge increase in sewage sludge production has occurred, as the consequence of the additional national sewage treatment now being applied nationwide, and society also happens from now on to need this as an energy source. It was, and to an extent still is now, a real problem finding ways to manage this sludge responsibly, but that HAS changed. Anaerobic digestion is the answer. It is there, it is proven, and the government is committed to subsidising it as an essential component of our energy policy which will allow the UK to comply with its 2020 renewables targets.

In other words; traditionally sludge has been considered a 'waste' requiring disposal, but that is rapidly changing.

A change in perception is obvious. Sludge is not going to be a waste any more, that is as certain as the fact that peak oil production has been reached, and that the days of huge fossil fuel resource discoveries has also passed. From now on sludge will have a resource value. A value which may be recovered through its use in the production of renewable energy, and primary feedstocks for chemical/ industrial processes.

The idea that only the Water Companies could be trusted with sewage sludge disposal, is now history. It simply isn't true. It's time to open up sewage sludge disposal to the market and allow the undoubtedly huge synergies which can then be realised between the Water Plcs and the UK Waste Management industry to flourish.

Examples of future synergistic relationships between the UK water industry and an open market in sewage sludge treatment include the large scale:

co-composting of sewage sludge with municipal green waste,
use of dried sludge as a substitute fuel in cement manufacture,
growing of energy crops (fertilised by sludge) for renewable energy generation,
co-combustion in power generation,
production of lightweight aggregates from sewage sludge cake and other previously landfilled wastes.

If this was opened up further and Water Plcs could form joint-ventures with the Waste Management Industry, and the advantages to the nation would extend still further, by relinquishing land assets within UK cities for recycling and solid waste treatment, just where they are so badly needed close to where the waste which is produced and needs recycling.

Process all types of waste together at those sites which are now only Wastewater Treatment Works. These are sites which could so easily be further developed as integrated waste treatment sites, facilitating recycling as a natural adjunct to city life. Not something done in obscure industrial estates on the edge of conurbations to where the current generation of these plants are thrust, by "NIMBY syndrome effects" on our planning system and by so doing are incurring huge dis-benefits in traffic generation and transport fuel wastage.

So, OFWAT here this plea from Renewable Energy News! Open up the market for sludge and release the Water Companies from restrictions on them which were once appropriate, but now threaten the ability of the UK to fully develop the new integrated resource management infrastructure. An infrastructure, without which "zero waste" must remain a pipe-dream forever.

Biogas to solve LPG crisis in rural Dakshina Kannada - Times of India

Biogas to solve LPG crisis in rural DK - Times Of India

MANGALORE: Rural schools, anganwadis and backward class and minority hostels in the Dakshina Kannada (DK) district need not shell out money to get refilled LPG cylinders anymore. DK zilla panchayat plans to set up biogas production plants in schools, anganwadis and backward class and minority hostels which would convert waste into cooking gas.




>
>


(Video and article are not connected.)


Many of the rural schools in the district find it difficult to get refilled LPG cylinders due to irregularities in the supply by the gas agencies. Biogas plants will help the schools cut down their dependence on LPG and firewood for cooking and not just save money.



While biogas produced in the plant will be used to cook mid-day meals in schools, it will be used in the kitchens of anganwadis and hostels. The zilla panchayat has already earmarked Rs 20,000 each to set up biogas plants in four centres in the district.


The plants will be initially set up in the anganwadi centres of Daddelakadu and Soornadu in Bantwal taluk, backward class and minority hostels in Bajpe in Mangalore taluk and Balthila in Bantwal taluk. See also www.anaerobic-digestion.com


Total sanitation officer of the district Manjula told STOI that an agency that quotes a suitable price will be given the task of setting up the biogas plants, which will reduce the burden on rural schools, anganwadis and hostels in several ways. In addition to saving money, it will also help to maintain cleanliness in the schools, the anganwadi and hostel premises as kitchen waste and other bio-degradable waste can be used as a raw material for the plant, she said.


The proposed plants will have the capacity to produce biogas, sufficient for two hours of cooking, with two kilograms of waste. Also power can be generated from the plant with the help of a generator, she said, adding that the work will commence soon.


More rural schools will be chosen where such biogas plants will be set up in near future, she added.

California bill a win for biogas - Biomass Power and Thermal

Anaerobic Digestion News

California Gov. Jerry Brown has signed Senate Bill 489, a law that allows small-scale biomass and biogas projects (1 megawatt or less) to qualify for the state’s Net Energy Metering program.




>
>


NEM allows a customer/generator to receive a financial credit for power generated by their on-site system and fed back to the utility. The credit is used to offset the customer's electricity bill. 


Previously, the NEM program applied only to wind and solar power generators. SB 489, or the Renewable Energy Equity Act, sponsored by Sen. Lois Wolk, D-Calif., allows all kinds of renewable energy forms to qualify for NEM.


“The most important component of this bill is its name,” said Patrick Serfass, executive director of the American Biogas Council. “Parity among all renewables is extremely important to be able to compete fairly in the market place.”


Serfass said he believes the majority of biogas projects will now be eligible for NEM, particularly farm- and wastewater-based projects. “If you look at the number of farm-based digesters in California, the number is about 11, which is really small considering what is possible. Out of the three main biogas feedstocks in California—ag waste, municipal solid waste and wastewater—two are directly related to the population, and California has a lot of people. The potential is massive.”
 


There are at least 30 landfills in the state that don’t have energy projects on them right now, according to Serfass. He added that the ABC is still looking into the exact impacts the bill could have, but said that it would definitely help new projects get installed and  into service. “This is a step in the right direction,” he said.

Dong targets biomass-fired CHP in the UK - Cogeneration & On-Site Power Production Magazine

Denmark's largest power producer says it is looking at the UK as a potential location for power plants that convert household waste to energy.


The UK government has said it wants to see an expansion in waste-to-energy and anaerobic digestion plants and has recently increased incentives for on-farm biogas technologies.


But so far the industry has been taking a wait-and-see approach until the government reveals further details on the future structure of renewable energy subsidies before it commits to new waste-to-energy plants.


Dong has a history in the biomass market and currently produces heat and electricity at three waste-fired CHP plants in Jutland, Denmark.


Dong has also established a consortium to investigate the potential of bioenergy technologies and which is also tasked with converting an existing biomass-fired CHP plant to allow it to handle waste products from a bioethanol plant.

Landia Chopper Pumps Improve Biogas Yields at UK Anaerobic Digestion Plant

Landia Chopper Pump installed at the feed to the AD Plant
Pumps made by Landia are playing a vital role in the success of a new 20kW anaerobic digestion plant at a 1,100 acre mixed farm in Hampshire.

Designed to provide all the benefits of large scale AD, but simplified so as to be achievable on a farm scale, the £100,000 plant includes both long-shaft and dry-mounted Landia pumps, which handle slurry from the dairy and leftover fruit and vegetable waste from the arable side of the farm.

It is true to say that even the notoriously difficult to handle AD feedstock punishment at installations of this type, hasn’t halted Landia pumps on the farm.
“We’ve done our level best to punish these Landia pumps with the thickest and most difficult materials we could thrown at them”;
said farm owner and Bioplex Technologies’ Director Chris Reynell,

“but they just keep on working, even though there are no excess liquids because we’re very much a solids-in, solids-out operation”.

He added:
“Landia had to meet our criteria for rugged and reliable equipment that could cope with heavy material such as silage, garden waste and horse manure, as well as slurry.  We’ve had no problems whatsoever.  The Landia pumps have accelerated the hydrolysis of the AD plant and help produce very healthy bacteria.  We have gained a significant upturn in biogas and benefitted from a superior compostable end-product, as well as enhanced fertilizer values.  It’s a great piece of kit”.
Chopper Pump Detail
Reynell also explained that the outlay included a new reception tank and a Combined Heat and Power (CHP) generator that provides electricity for his farmhouse. With the savings made from not having to buy artificial fertiliser and reduced fuel costs for the generator, he estimates a payback period of 5 years.

The pumps installed at this site are Long Shaft Chopper Pumps:  MPG 4” 7.5kw complete with cutting knives.



About Landia




Landia is a family-owned company that was founded in 1933 in Denmark.  In 1950 the company invented the first efficient electric pump with rotating knives, which is the main principle behind today’s modern chopper pump (as it is now called), which is used all over the world. 

Over 75% of Landia’s business is export, with its pumps, mixers and process units in successful use across numerous industries, including sewage treatment plants, biogas, agriculture, fish, food and brewing.  Landia prides itself on high quality products and a back-up service to its customers to match’.

Elephant-poo power electrifies zoo - CNN

Zoo in Germany partially powered by electricity produced from animal dungAnimal waste fermented for 30 days generates "biogas"


Energy produced enough to heat 25 homes and power 100




>
>


(The video is not related to the article.)


Munich, Germany (CNN) -- At Munich Zoo you can watch the courtship rituals of the banded mongoose, hear the morning song of the scarlet ibis or visit the Indian elephants, who help keep the lights on with electricity generated from their dung.


They can do this because Munich Zoo has harnessed "poo power," energy stored in animal waste, which can be converted into a fuel known as "biogas."


It works like this: The zoo has built three large containers, each capable of holding about 100 cubic meters of animal waste -- that's around a week's worth of dung collected from all the vegetarian animals in the zoo.


Once inside the containers, it's mixed with warm water and the bacteria in the dung is left to decompose in an oxygen-free environment for 30 days.


The resulting biogas, mainly comprised of methane and carbon dioxide, rises naturally through vents in the ceiling to a corrugated hut on the roof where it's collected in a "big balloon," says park supervisor Dominik Forster.


The biogas is then fed into a gas-powered engine that's used to generate electricity. Forster says that the balloon -- which more closely resembles a small Zeppelin -- can store enough biogas to meet 5% of the zoo's energy needs.


By the time the food has been digested by the animal, a lot of the energy in it has been used up or burped out
Dr Geraint Evans, National Centre for Biorenewable Energy
"When you turn the biogas into electricity, it creates heat which we also store," says Forster. This is then used to warm the gorilla enclosure, "but could be used to heat about 25 homes," he adds.


Once the fermentation process that creates the methane is finished, the remaining solid matter, or "digestate" is used as an organic fertilizer for crops that will later be used as feedstock for the animals.


"We don't waste anything," said Forster, who claims that his is the only zoo in Germany to generate electricity in this way.


A mature elephant can eat about 100 kilograms of fruit, vegetables and pretzels a day, producing a mountain of dung and Forster says that all the zoo animals together create roughly 2,000 tons of the stuff every year.


This is enough to power about 100 Munich households -- a drop in the ocean when you consider Munich's population, which is 1.3 million, according to CIA World Factbook.


The problem is that dung alone does not produce all that much energy relative to its size, says Geraint Evans, head of biofuels at the UK's National Centre for Biorenewable Energy, Fuels and Materials.


"By the time the food has been digested by the animal, a lot of the energy in it has been used up or burped out," he said. "It's more efficient to just put the feed directly into the biogas generator." [See also http://anaerobic-digestion.com ] 


Even if the returns are small at this stage, Evans says this project and others similar are still worth it.


"It's really important that we change our mindset from dependence on one source of energy to many different complementary sources," Evans said. "Animal waste can create electricity, heat, fertilizer ... even clean water can be extracted from the solids to spray on crops ... So, it's emblematic of this very holistic approach."


In this spirit, Forster says there are now plans to install photo-voltaic solar panels on top of the animal enclosures over the coming year.

Feces-Powered Motorcycle? Bullsh*t What Do You Think?

Let us put the record straight!


A three-wheeled motorbike that runs on the rider's feces? It sounded much too unsanitary to be true. Sure enough, the Toilet Bike Neo isn't powered by waste generated by its rider?! No, sorry to disappoint you, but it isn't!


It is an operational bike, though, and it's being powered by biogas fuel as it makes its way across Japan.




>
>


The creator is high-end toilet manufacturer Toto, which devised this conceptual model to publicize the company's environmental initiatives. The seat is one of Toto's advanced toilet models, the Neorest AH3, but the toilet isn't operational.


The engine runs on biogas fuel, which is made from a substance that comes from human and animal waste products. The biogas is contained in two compressed gas cylinders, which are mounted on the bike and hold enough for the bike to run about 300 km without refilling, Toto says.


More than a few publications reported the bike runs on waste generated by the rider. WTOP said Toilet Bike Neo "converts the poop -- which can come straight from the driver sitting on a toilet-style seat -- into a biogas that propels the vehicle." Huffington Post repeated that disgusting claim, saying that human waste is stored in the driver's seat and citing WTOP.


The Daily Mail was confused, too: "Bizarrely the rider is even encouraged to use the portaloo as much as possible on every journey as the waste is turned into biofuel which powers the machine."


Ubergizmo's take?  "Yes sir, yesterday's processed lunch and dinner will get you places, thanks to the biogas converted from feces that is harvested straight from the rider." 


Nope. Not true.


Amidst all the inaccurate reports, Toto published this explanation on its web site:


"TOILET BIKE NEO does not have the mechanism to run on the rider's waste. It runs biogas fuel (fertilized, purified and compressed livestock waste and household wastewater) provided by Shika-oi Town in Hokkaido and Kobe city. Therefore, the NEO REST seat does not function as a toilet, and has been created for promoting TOTO's environmental efforts. TOTO is not involved with any motorbike or biogas production business."


Music and secret messages are part of Toilet Bike Neo's allure, however. Six car horns can perform the "Toto Benki No Uta," or the Song of Toto Toilet. A vertical string of LED lights displays a message that can only be seen at night.

Researchers Achieve Breakthrough in Treating Biogas and Bio-butanol to Develop ... - AZoCleantech

By Cameron Chai


While Bio-butanol can be generated by using spin-offs of the pulp and paper industry and food industry to substitute petrol, methane realized from biogas, as revealed in the life-cycle assessment is seen as a top prospective to substitute fossil fuel.




>
>


(The video is not related to the article.)


Professor Ulla Lassi, a researcher from the University of Oulu, has tried the manufacture of butanol through a chemical synthesis process, which deploys a new catalyst material to change compounds such as ethanol, methanol or glycerol into alcohol, pentanol and butanol blends, which can be directly utilized as liquid fuels. He found that usage of glycerol, a by-product of biodiesel will be more cost- efficient. According to Lassi, the current discoveries in butanol fermentation methods have solved the experienced problems partly and he explained that new catalyst development and new chemical sysnthesis methods alone will enable the manufacture of new type of liquid fuels.


Another research, a joint Finnish-Chilean endeavor under the SusEn research program, tried the use of biogas as a transport fuel. The research tried methods to upgrade the landfill gas into fuel. According to the principal researcher of the project, Professor Jukka Rintala, in recent years a good amount of interest has been shown in the use of biogas sourced from energy crops and biodegradable waste. Such biogas is either utilized to run the vehicles or fed into the grid as natural gas for usage and the waste material known as digestate is used as a soil conditioner or fertilizer.


Rintala carried out the project at Jyväskylä located Mustankorkea Waste Treatment Facility, which focused on removing trace compounds of biogas. The method attempted to raise the methane content in biogas to facilitate its usage as biofuel. It utilized the water absorption method, which enabled the yield of methane content up to 80 to 90 % and the rest was found to be nitrogen and carbon dioxide. While nitrogen content reduced the energy subjects of biogas, its carbon dioxide brought down the energy value of biogas. The research suggests preventing the access of nitrogen in the landfill located gas collection system to lower its content in the collected methane.

Biogas Europe Conference Features Biomethane for Transport

Biomethane and its applications is a crucial topic for biogas’s future development across Europe. As such it has been accorded a half-day segment at an upcoming Biogaz Europe conference, to be held on October 25-26 in Nantes, France. The afternoon session with start off with an overview of the status of biomethane today in Europe from Andy Bull, Project Co-Ordinator of the IEE project, BioMethane Regions. The French biomethane context for direct injection and for transport will be given by GRDF and the French Natural Gas Vehicle Association (AFGNV).

>>
(Video is not connected with the conference.)
Additionally, four innovative case studies will exemplify the benefits of biomethane for transport (from Sweden, UK, Austria and France).
Valtra Tractors (SE) : The Valtra N101 dual-fuel tractor has 110 horsepower and is intended as an all-purpose tractor for farms, municipalities and contractors that have the possibility of refuelling with biomethane while working. Without making any changes to the original diesel engine, 70 to 80 percent of power is generated by biomethane. The dual-fuel engine functions like a diesel engine and performs the same whether operating on dual-fuel or just diesel. The gas is injected with the intake air, and combustion occurs when a small amount of diesel fuel is injected into the cylinder. If biomethane is not available, the engine can run completely on diesel fuel.
Adnams Brewery (UK) : Adnams Bio Energy Limited has constructed and is now commissioning a groundbreaking anaerobic digestion (AD) plant, which will be the first in the UK to use brewery and local food waste to produce biomethane for direct injection into the national gas grid (in partnership with British Gas and the National Grid) as well as providing gas for use as a vehicle fuel. In the future the facility will produce enough renewable gas to power the Adnams brewery and run its fleet of lorries, while still leaving up to 60 per cent of the output for injection into the National Grid.
Fuchsn’hof, Austria (AT) : Austria’s first biogas feeding-plant has been operating in Upper Austria since June 2005. This pilot project supplies the existing natural gas grid with biogas up-graded to natural gas quality. Fuchsn’Hof, an existing biogas plant that used biogas for generation of electricity, now serves as a gas production plant. The substrate consists of a mixture of manure from 10,500 hens and 50 breeding pigs.
BioEnergie de la Brie (FR) : BioEnergie de la Brie is a project under development which anticipates to utilise a blend of cattle slurry, vegetable, cheese production wastes and cereal residues to produce and upgrade biogas to biomethane quality for direct injection to the gas grid.

United Plantations plans more biogas plants - Malaysia Star

TELUK INTAN: United Plantations Bhd (UP) plans to add more biogas plants in one or two years at its palm oil mills in Malaysia and Indonesia to save energy cost.

Vice-chairman/executive director (corporate affairs) Datuk Carl Bek-Nielsen said the company reduced 25% of fossil fuel usage yearly at its Perak plantation by relying on electricity generated from its biogas plant in Teluk Intan.

 Lim says in view of the fuel-price volatility, plants will enjoy significant cost-savings as the energy generated will reduce the dependency on fossil fuel.

“Currently, we have three biogas plants in the country and they help a lot in terms of cost-savings. Though it is costly to set up a biogas plant, the impact that we receive is really worth it,” he told reporters during a media visit to UP's plant here.

He said the cost of building a biogas plant was about RM7mil and the group had invested RM20mil for its existing three plants.

Meanwhile, Dr Lim Weng Soon, director of Malaysian Palm Oil Board's engineering and processing research division, urged more palm oil mill operators to build biogas plants to boost revenue.
“Mills can use steam or/and electricity generated from the biogas plant for their own use. In view of the fuel-price volatility, plants will enjoy significant cost-savings as the energy generated will reduce the dependency on fossil fuel,” he said.

Under the Palm Oil National Key Economic Area of the Economic Transformation Programme (ETP), the country is targeting 500 biogas plants by 2020.

Lim said Malaysia was on track to achieve the target. “There are currently 46 in operation, 22 under construction and another 46 in planning stage.”
Lim said the three states with the highest number of plants are Sabah (10), Johor (nine) and Perak (eight). Of the commissioned plants, 18 are generating electricity for their own use. [Also see http://anaerobic-digestion.com ]

The biogas plant under the ETP are expected to generate about RM2.9bil in gross national income and create 2,000 jobs by 2020.

In assisting independent millers to fund the development of their biogas plants, an existing Green Technology Fund of RM1.5bil is being set up by the Energy, Green Technology and Water Ministry.

Research: From landfill biogas to transport fuel - Recycling News

Helsinki -- Within the Academy of Finland?s research programme Sustainable Energy, researchers looked at the use of biogas as a transport fuel. As a joint Finnish-Chilean effort, the researchers studied the upgrading of landfill gas into fuel. ?In recent years, interest in using biogas technology in the utilisation of industrial by-products for energy purposes has increased considerably. Some countries have already introduced this technology on a large scale, says Professor Jukka Rintala, the principal investigator of the project.


Our video for this post is on the subject of Finnish Biogas. There is no association between the video and the article.

Biogas can be produced from many different materials ranging from biodegradable waste to energy crops. The biogas produced in this process is a versatile source of energy. It can be used for heat and electricity, be processed into vehicle fuel or fed into the natural gas grid. In addition, the residual material, the so-called digestate, from the process can be used as fertilizer or soil conditioner,? Rintala explains.
Methane derived from biogas has been shown to be one of the most suitable candidates for use as biofuel, thanks to its sustainable production chain. Methane also meets the EU?s criteria for sustainable biofuels, which will take effect in a few years? time. Rintala: ?Biogas can be used as a biofuel once its methane content is raised above 95 per cent. In our research, we used water absorption, which yielded a methane content of 80?90 per cent. The rest is carbon dioxide and nitrogen.?


Nitrogen does not cause any damage to car engines, but it does lower the energy content of biogas. To reach a higher methane content through this process, we should prevent the access of nitrogen in the gas collection system in the landfill. Carbon dioxide does not damage engines either, but it lowers the energy value of biogas, says Rintala.


Rintala would like to see more research on the effects of process parameters on the costs of biogas upgrading and the effects of pressurisation on compound removal. As a rule, the only criterion for biomass is that it can be broken down by microbes under oxygen-free conditions. Of course, the composition of feedstocks does affect the composition of the biogas produced and also the chosen method of purification. Landfill gases are generally thought of as being the most difficult ones to upgrade into fuel.? Quelle: Academy of Finland

Somerset council approves biogas extension - BioEnergy News

Somerset council approves biogas extension

17 October 2011

A biogas facility in Somerset, south west England, has been given approval to double its current capacity to power 4,000 homes.


(The follwing video stays on the "Somerset" subject matter of this post, but shows an un-associated AEROBIC composting facility. While this is excellent bio-management, aerobic systems, although cheaper to build and operates, aerobic processing does not produce any biogas or any energy at all, and in fact require substantial energy inputs to operate.)

Currently the Cannington Enterprises plant uses an anaerobic digester to produce power from residue crops such as maize silage, grass, whole crop and big bale silage but it will now be allowed to treat up to 75,000 tonnes of other waste such as rotting food.


A number of residents objected to the original application, made in March, because they believed it would create excess traffic on narrow roads and that the smell would impact tourism in surrounding areas.


The company needs to prepare an odour management plan, a noise management plan and landscape plan before commencing the build. http://anaerobic-digestion.com


As part of the extension, the company plans to extend a tanker loading to an existing building, build a separator facility for the ‘spent digestate accompanied by a solid digestate bay and liquid digestate tank’, and construct a maintenance building and gas holder.
