Cost of Anaerobic Digestion in the UK: WRAP Annual Gate Fees Report 2022
The cost of anaerobic digestion in the UK is reported for those seeking to operate their own biogas plants as below: Latest 2022 Annual WRAP Gate Fees Report Another indicator of the rising demand for food waste and the highly geographically variable degree of supply and demand in the market for anaerobic digestion for those […]
What is Biogas? Beginner’s Anaerobic Digesters Large & Small
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
In this article, we will look back at our March 2013 article when UK Anaerobic Digestion Plants exceeded 100 and were receiving damaging media attention due to novice operators causing some high-profile environmental problems. So, we reported that they were “hitting trouble”. The fact is that now (in 2023), with the benefit of hindsight, we […]
Anaerobic Digestion Basics and 5 Tips on How AD Works
We bring you the Anaerobic Digestion Basics (AD) and if you scroll down, 5 tips on how AD Works. AD is in-truth an unhelpful acronym for the basic age-old natural process that produces renewable energy as heat and biogas, and at the same time makes a natural crop fertilizer. That, in a nutshell, is basic […]
Biogas Potential is Too Small to Make a Difference – 2 Myths Busted! WBA Report Shows
How large is the biogas potential in terms of energy output? Can there ever be enough anaerobic digestion plants to really make enough of a difference to significantly reduce global carbon emissions? The pessimists peddle the 2 main myths that: 1) the energy yield from biogas production is too low, which makes it uneconomical and […]
Xergi Biogas Plants – 5 Advanced Plant Construction Themes
The Xergi Biogas company, Denmark’s market-leading supplier of AD technology (2017) has been building a successful biogas business in the UK, and around the world, for over 10 years (2022). They have multiple anaerobic digestion plants now either operational or in construction. New Xergi biogas plants are announced every few months. As you can see from […]
What is Renewable Energy and How Does It Work
Renewable energy is the world’s fastest-growing energy resource. Renewable Energy is derived from natural processes that are replenished by human or natural systems. Over most of human history, fire has been used as a low-tech, low-cost method to produce heat and provide light. Renewable Energy technologies ultimately strive to reduce dependence on burning fossil fuels […]
Landia Digester Tank Mixers Still Brilliant 8 Years On
Digester Tank Mixers installed by Landia really do matter says Eco because the output of methane and even the stability of the anaerobic digestion process are dependent on the effective mixing of the digester contents. Scum and froth are minimised and gas output is maximised by the use of an efficient mixing process. In addition, […]
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 […]
