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 […]
Anaerobic Digestion Process Steps: From Trash to Cash
There are just four core biochemical anaerobic digestion process steps. They are Hydrolysis, where complex organic matter is broken into simple sugars and amino acids; Acidogenesis, where these are converted into volatile fatty acids, hydrogen, and carbon dioxide; Acetogenesis, where fatty acids are transformed into acetic acid, and finally Methanogenesis, where acetic acid, hydrogen, and […]
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 […]
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 […]
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 […]
