Anaerobic Digestion Process Steps: The 4 Stages Explained
Anaerobic digestion takes place through four closely connected biological process steps: hydrolysis, acidogenesis, acetogenesis and methanogenesis. Together, these microbial stages convert complex organic material into biogas—principally methane and carbon dioxide—and digestate. New to the subject? Start with our complete introduction to anaerobic digestion. This article concentrates specifically on the biochemical process steps, the compounds produced at each stage […]
Food Waste: Packaging Contamination Threatens Processing Feed for Anaerobic Digestion
Packaging contamination in the food waste recycling industry occurs when inadequate separation of the packaging from food waste occurs, and when physical contaminants such as microplastics and nanolastics are introduced into anaerobic digesters from the packaging itself. You toss out expired yoghurt, a mouldy sandwich, and soggy lettuce. Each one sits in a wrapper or […]
COP29 Declaration on Organic Waste a Pivotal Moment for Biogas
The much maligned COP29 event this November, and the “COP29 Declaration on Organic Waste” may eventually prove to be a pivotal moment, a breakthrough, for the full development of anaerobic digestion and biogas production globally. As the world confronts alarming projections for climate change, the COP29 Declaration on Organic Waste will be a much needed […]
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 […]
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 […]
