Hydrolysis of Sewage Sludge and Anaerobic Digestion Wins
The hydrolysis of sewage sludge and the subsequent anaerobic digestion of the hydrolysed sludge output is becoming increasingly common at many sewage works. We think we are justified to call it a winning combination, and we even back up this assertion by providing information on a new contract win for the technology by Veolia, in […]
What is Biomethane and Anaerobic Digestion Gas to Grid Definition
It is a good question to ask; “What is biomethane and anaerobic digestion gas to grid”, but for the first part (biomethane) don’t expect always to get the same answer! Many people use the term biomethane interchangeably as if it means the same as biogas. In fact, when the term “biomethane” is used correctly the […]
Anaerobic Digestion Plants
An AD plant creates controlled conditions for microorganisms to break down organic material; our guide to how anaerobic digestion works explains the process and its main outputs. In this section of the website we explain Anaerobic Digestion Plants by country and the progress in recent years which has been made in the implementation of AD […]
Anaerobic Digestate Disposal, or Use as a Natural Fertilizer?
The question as to whether to go for Digestate Disposal, or use it as a Natural Fertilizer is important, and not a simple one to determine. Digestate from any wet anaerobic digestion process comprises both a liquid and a fibrous solid material. As we plan Anaerobic Digestion Plants the question arises for each site as […]
Anaerobic Digestion Feasibility Study List of 10 Examples
Have you ever considered doing an Anaerobic Digestion Feasibility Study? If you are wondering about whether or not to build your own biogas plant, sooner or later most people consider embarking on an Anaerobic Digestion Feasibility Study.

Anaerobic Digestion of Kitchen Waste – All You Need to Know
The anaerobic digestion of kitchen waste (also known as food waste anaerobic digestion) has become of great interest in recent years due to the high organic removal rates and positive net energy balance which can be achieved in well designed and competently operated anaerobic digestion plants. Anaerobic digestion is recognised by the UK government, Defra, the […]
Is My Waste Suitable for Anaerobic Digestion?
“Is my waste suitable for anaerobic digestion?”, is a frequent question we receive in our emails. It comes from those considering installing agricultural AD systems, and businesses that produce food waste especially. There are two immediate considerations for any answer, the first is to say that more or less any organic material can be anaerobically […]
Advantages and Disadvantages of Anaerobic Wastewater Treatment vs Aerobic
The principal advantages and disadvantages of anaerobic wastewater treatment, when compared with the aerobic equivalent processes, are listed and then discussed below. Advantages of Anaerobic Treatment Less energy required Less biological sludge produced Lower nutrient demand Methane production: Providing a potential energy source with possible revenue both from the sale of the energy and benefit […]
