Check out our latest video "8 Biogas Uses" which is aimed at a common search term. If you know of any other uses we would be pleased to be informed and can then make another video with your suggested additional uses. #anaerobicdigestion #biopgas #biogasuses
8 Biogas Uses List – How Biogas is Used to Make Lives Sustainably Better.Here is our list of 8 biogas uses point by point.
1. Electricity Generation as a Biogas Use.
2. Upgrading Biogas to Biomethane (RNG).
4. Burning Biogas in Domestic Gas Stoves.
5. Biogas Use as Fuel for Portable Electricity Gen-sets.
6. Using Biogas Carbon Credits as a Means to Obtain an Income from CDM Payments in Qualifying Countries.
7. Compression of Biogas to Fill Gas Cylinders.
8. Direct Conversion of Biogas to Electricity in a Fuel Cell.
We hope you have been enjoying watching our list of eight biogas uses.
Have you ever thought of getting involved by producing biogas, or promoting the idea of large-scale commercial biogas production in your area?
Biogas is a sustainable renewable fuel which can be made for as long as man grows crops and eats food.

Co-disposal of Food Waste and Sewage Sludge - The Video Text follows:The idea of co-digestion by mixing food waste and sewage sludge, is new to the UK, but it makes fairly obvious good-sense.
Currently, reforms from Ofwat in the UK, are separating the tasks of treatment and exploitation of sewage sludge into an individual new market.
Therefore, now is a good time to invest in sludge treatment.
When the UK water industry was privatized in 1989, nobody thought that sewage sludge would become a valuable source of bio-energy, with efficient anaerobic digestion plants, capable (as they are now) of powering sewage treatment works.
And, often with enough electricity left-over to export as well!
In those days (to allay public concerns about pollution from sludge) the privatized water industry was not allowed to send any sludge away to be disposed of by "irresponsible" sub-contractors.
In effect, the UK water industry has not been allowed, until now to co-dispose other wastes with their sludge, or indeed to contract-out sewage sludge treatment off-site to other companies, such as AD plant operators.
And yet there are big gains to be made!
With energy costs making up a large proportion of operational cost for water companies, the creation of green, renewable energy from what was previously considered a waste product can make a significant difference to the bottom line.
Back in 2016 Ofwat’s preliminary estimate put a £780M value on the sludge co-disposal market, said Elaine Coles, Editor of Waterbriefing.
Everybody involved in the UK water industry and biogas industries is now seeking benefits from the combined disposal of waste such as food waste with sludge, allowing improved biogas yields, from more efficient AD plants, and from better quality bio-solids.

A Big New Advantage of Anaerobic DigestionThe UK’s Committee on Climate Change (CCC) is the body which advises on how the UK will meet its obligations to reduce climate change, in the “Paris Agreement”.
No-one can deny that all governments need to help reduce climate change.
Climate change threatens the land’s ability to provide critical services including clean water, healthy soils and timber, and ensure sufficient food production for an increasing population, and threatens to reduce space for new homes.
They say that a good way to reduce the climate change arising from excess carbon (CO2) in the atmosphere is to hold more carbon in the land (soil).
At the same time this would improve soil fertility, and provide more food.
So, they are recommending that fundamental reform is implemented to ensure land becomes a more effective carbon store.
To store this carbon a source of suitable organic material will be needed.
Biogas Plants (anaerobic digestion processes) are ideally suited to providing this, by creating the necessary carbon for return to the land, from their fertilizing output, known as digestate.
This is a newly discovered advantage of Anaerobic Digestion, to add to the existing advantages, the biggest of which is the production of renewable energy in the form of biogas.
