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 […]

Anaerobic Digestion Germany – Biogas Industry Sells Its Leading AD Technology Abroad

Anaerobic Digestion in Germany is quiet, as far as selling at home goes. Very few new local German AD plants are in development currently (2019). The German Anaerobic Digestion Equipment industry is active, but is mostly making biogas equipment for export. The internal market is flat and likely to remain so for some time. Watch […]

Anaerobic Digestion Regulations – UK Environmental Protection, Animal By-products, Duty of Care, Health and Safety

Anaerobic Digestion Regulations surprisingly, don’t exist in the UK. At least not all neatly bundled into a single government act or rule book. Instead, AD Plant operators must comply with a range of statutory requirements (“Laws” to you and me). The four which must be tackled once Planning Permission has been obtained are as follows: […]

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 […]

Basic Anaerobic Digestion – How Does Anaerobic Digestion Work?

Anaerobic digestion (AD) is in-truth an unhelpful name for the basic age-old natural process that produces renewable energy as heat and biogas, and natural crop fertilizer. That is basic anaerobic digestion, and how the AD (or fermentation) process works. The following video is a very popular video which explains how AD works: A common challenge […]

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 […]

Biogas Production Improved from Wastewater Treatment Works Thickened Sludge

Biogas production improvements that raise the yield of methane from any given quantity of biomass fed into an anaerobic digestion plant are the holy grail of AD. The one thing which, above all else, is holding back on the development of anaerobic digestion is the current level of profitability which, while viable for many businesses […]

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 […]
