ROCs Explained and Why 2017 Closure Shocked the UK AD Industry
ROCs Explained! In this article we explain ROCs (Renewables Obligation Certificates). And, why the 2017 closure of the scheme to new generator capacity and businesses for Anaerobic Digestion was a big shock to the UK AD industry at the time. To many people it still seems like a mistake and a missed opportunity for UK […]
Anaerobic Digestion Basics – How Does Anaerobic Digestion Work?
We bring you the Anaerobic Digestion Basics (AD). ADÂ is in-truth an unhelpful name 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 anaerobic digestion, and how the AD (or fermentation) process works. How Does […]
Food Waste AD – The Anaerobic Digestion of Inedible Food for Energy and Natural Fertiliser
Food Waste AD is the short way to refer to the anaerobic digestion of inedible food for renewable energy and natural fertiliser. That sentence encapsulates the core philosophy of the movement towards food waste AD. “It’s a crying same that any food is wasted while so many people struggle to feed themselves. Mechanically digesting this […]
UK Food Waste Anaerobic Digestion Plant History of the Ludlow Digester
In the UK Food Waste Anaerobic Digestion Plant History began with the dedicated Food Waste AD Waste Technologies Demonstrator Plant, known as the Ludlow Digester. In the UK the history of dedicated food waste anaerobic digestion plants began there in 2004, when the innovative government funded plant opened. At the time, nobody was sure that […]
Aerobic Digestion and Anaerobic Digestion – A Comparison
Any comparison of Aerobic Digestion and Anaerobic Digestion should first explain that a comparison can be made either on the basis of either: microbiology ( the study of microorganisms) or respiration systems in man and mammals generally. In this article we compare (1) aerobic digestion with anaerobic digestion (2), in the context of microbiology and […]
Changes in UK Small-Scale AD Subsidies – Reductions to New Applicants
This is for those interested in UK Small-Scale AD Subsidies.

Waste Autoclave Pretreatment with Anaerobic Digestion for Household Waste
Waste Autoclave pretreatment of residual household waste, and food waste, for all its undoubted advantages in increased biogas yield during subsequent anaerobic digestion of the organic fraction, has met with a difficult period. The story has not been a good one, since we originally posted our article on this subject in May, 2012. In a […]
Anaerobic Digestion in the US Shows Growth Despite Low Electricity Prices
Anaerobic Digestion in the US is expanding despite no subsidies, in most cases. Many opinion-formers suggest that Anaerobic Digestion technology needs strong subsidies to have a chance of being developed to meet its potential. However, US AD site “Biocycle”, has posted an article which suggests the contrary. It says that’s not the case in the […]
