How Biomass Feedstock Storage Can Be a Waste of Space
Biomass feedstock storage (for example installing a silage clamp) is a new subject that is rising rapidly in prominence, following the recent expansion in the number of anaerobic digestion plants. Current low-cost designs can easily be a shocking waste of space. This fact is becoming clear now that there are many anaerobic digestion plants in operation. […]
5 Things You Should Know Before Designing a Biogas Plant
We sat down and wrote this article on “5 things you should know before designing a Biogas Plant” to help our readers to create the best biogas plant design in 2015. Six years later, we looked back, and we think this information is still relevant and useful. (But, we have added some additional hints and […]
Biogas Plant Substrate Mixing During Fermentation Creates a Stir with AD Plant Operators
Better biogas plant substrate mixing during fermentation is great news for a biogas operator. The importance of “creating a stir” in the fermentation tanks of fully mixed bio-reactors is huge. It provides better biogas yields and improved process stability. And, this is becoming much better understood. Many AD plant clients around the globe are discovering […]
Cost of Anaerobic Digestion in the UK: WRAP Annual Gate Fees Report Published
The cost of anaerobic digestion in the UK is reported for those seeking to operate their own biogas plants as below: Annual WRAP Gate Fees Report Another indicator of the degree of supply and demand in the market for anaerobic digestion for those that don’t have their own digester and wish to dispose of waste […]
Bio Thermic Digester (BTD) Gains Acceptance And May Become Major Competitor To Anaerobic Digestion
Bio Thermic Digester (BTD) is the term for an innovative type of industrial-scale biological high temperature-digester which uses Aerobic Extremophilic Bacteria to achieve a remarkably high level of mass reduction and has been launched by waste treatment specialist Advetec. The technology is understood to be capable of rapidly processing significantly high volumes of organic municipal waste, […]
US EPA and USDA Boost Anaerobic Digestion and Biogas as a Major Renewable Energy Source
The US EPA and USDA have recently updated and extended their anaerobic digestion and biogas plant sections. This will further boost the uptake of anaerobic digestion technology and biogas/ biomethane production as a major renewable energy source. At the same time, there is recognition that anaerobic digestion has many other benefits, and these too are […]
Improving Biogas Plant Efficiency – Why Ferrous Chloride Dosing Not Ferric Chloride is Best
Seeking to improve biogas plant efficiency and understanding why Ferrous Chloride, Not Ferric Chloride, is the best of the two as a dosing additive within a balanced biogas output-raising product. During a recent exhibition stand enquiry I was making, an expert from Lukeneder helped me understand this point. She explained the differences between Ferrous Chloride […]

What is Biogas? A Beginners Guide – Home to Commercial Digester Systems
We answer the question: “What is Biogas?” Biogas is generated during anaerobic digestion (AD) when microorganisms break down (by eating it) organic materials in the absence of air (or oxygen). Biogas is mostly methane (CH4) and carbon dioxide (CO2), with very small amounts of water vapor and other gases. The carbon dioxide and other gases […]
UK Anaerobic Digestion Plants Exceed 100 And Hit Trouble: Looking Back
Looking back at our March 2013 article when UK Anaerobic Digestion Plants exceeded 100 and we thought they were hitting trouble, by causing environmental problems. With hindsight, (in November 2019) we can see that we were wrong. Yes, of course there have been teething problems with new biogas plant owners. Some started out, not appreciating […]
