Biogas Storage Holder Installed for Burdens Environmental Plus Video

Burdens Environmental have recently developed their own high tech Anaerobic Digestion plant. On viewing one particular answer to Biogas Storage at the environmental trade show ETSUK 2012, Burdens group recognised immediately the benefits of the simple, modular spherical Biogas Storage unit. This was first and foremost due to the fact that it matched perfectly the ethos behind the design of their new AD plant, in which every component of the system is an individual “plug and play” unit. See that artic;le below our video.

Watch our video below for more Biogas Storage information. While on ths subject of Biogas Storage spheres we thought that this video of an alternative offering would be of interest to our readers.

When Fred Bartlett, consultant to Burdens, first viewed our working model he was so impressed he commented “If I had the cash on me I would order the first one now!”. Following this successful first viewing Base are installing a 25m3 Biogas Storage sphere on AWS Burdens Environmental trial plant in Carmarthenshire, South Wales later this month.

By combining modular components to build systems, the Burdens model can be scaled up as demand increases, helping to manage the risk of a large speculative investment. Every part of each sub assembly can be bought off the shelf and bolted together to grow larger and larger systems. When it becomes unfeasible to keep adding parts and sub-assemblies then a step-change is taken up to the next size of system. In this way all possible AD needs can be catered for in 3 practically sized ranges, capable of processing 30 tonnes of waste per week up to 100 tonnes per week.

Base welcomes enquiries from both partners and potential customers. For further information please contact Fran Buchanan on +44 (0) 117 971 2229, email francisb@basestructures.com or visit the Base Structures Biogas Storage microsite.

United Ethanol to install anaerobic digester

A $6.75 million project to install an anaerobic digester at a 50 MMgy ethanol plant in Milton, Wis., will begin in a few weeks. United Ethanol LLC will complete the project with the help of $2.25 million in state energy program funds.

It's a way to extract a little more value out of our inputs, the corn, and make the plant greener and more energy efficient, said Alan Jentz, United Cooperative and United Ethanol vice president of grain operations and risk management.




On Oct. 21, Wisconsin Gov. Jim Doyle announced $2.95 million in funding for three southern Wisconsin companies, including United Ethanol. The money comes from Wisconsin?s economic development tax credits and energy program, which is funded through the American Recovery and Reinvestment Act.

The other two projects were $250,000 in tax credits for Standard Process Inc., a whole food supplements company, and $450,000 in energy program funds for Idle Free Systems Inc., which sells battery-powered, idle-elimination systems for over-the-road trucks.

In total, more than $55 million in state energy funds from the recovery act are being used in Wisconsin to help manufacturers with energy efficiency and renewable energy projects. According to the governor's office, Wisconsin is the only state using 100 percent of these funds for these types of projects. In August, Ace Ethanol LLC received $595,000 in funding from the same program for heat exchange equipment.

United Ethanol's anaerobic digester will utilize a portion of the plant's thin stillage to create methane, which will help reduce natural gas use at the plant by up to 25 percent. The project will have an estimated four-year payback, Jentz said.

The project has multiple benefits, including reducing the plant's carbon footprint. The anaerobic digester is also expected to reduce the number of fermentation solids that have to be recycled, reduce fermentation inhibitors, reduce evaporator bottlenecks and eliminate syrup load-out, Jentz said.

Technology provider Eisenmann Corp. will install the digester. The project should take about a year to complete. We hope to get that under way here in the next few weeks, so hopefully it will be online by this time next year,? he said.

Anaerobic digestion isn?t the only technology upgrade project United Ethanol has on its plate. David Cramer, president and CEO, mentioned three projects in the company's August newsletter. The company is working to tie in the CO2 scrubber stack and process vent gas scrubber stack into the regenerative thermal oxidizer for odor control.

In addition, it has a license agreement with GreenShift Corp. to use its corn oil extraction technology. United Ethanol has also contracted with Arisdyne Systems Inc. to install controlled flow cavitation, a patented process to reduce particle size, disrupt cell structures and disperse agglomerates for increased ethanol yield.
