General

The term “Biogas” refers to gases produced by the anaerobic fermentation of biological materials. Their major constituents are methane and CO2.

Biogas is a clean uncontaminated and cheap source of energy especially useful in off grid locations. It consists of 55-70 % methane which is inflammable.

Many say that without it being used, there can be no “Zero 2050” carbon emissions achieved for our world.

What are AD Plants? – Decarbonizing Biogas Plant Information

So, you would like to know what are AD Plants? Here we bring you the AD Plant Information and put simply, an AD plant is a shortening of the term anaerobic digestion plant. What is mainly used for the production of biogas and placed inside the fermenter (a special container) are Food scraps. Also, sludge […]

Why Anaerobic Digestion? Reasons to Support Biogas

Asking: “Why anaerobic digestion?” is a good question. After all there are other ways to produce renewable energy, and other fertiliser sources many of which can be cheaper in terms of the direct cash to buy them. There are even other ways to dispose of food waste and to prevent farms polluting rivers and streams. […]

Anaerobic Digestion Energy – Gaining Value from Biogas Energy Content

Anaerobic Digestion Energy the sustainable renewable energy production process, is on an upward trend. The establishment of anaerobic digestion (AD) systems has accelerated substantially in the past several years. And, one area of growth is for livestock manure stabilisation and the associated energy production. There are thousands of digesters operating at commercial livestock facilities in […]

What You Wanted to Know About Anaerobic Decomposition But Never Asked

Here it is: It’s all the facts that you wanted to know, about Anaerobic Decomposition, but maybe never asked. Decomposition Without Air Defined Succinctly The first step is the decomposition (hydrolysis) of plant or animal matter. This step breaks down the organic material to usable-sized molecules such as sugar. The second step is the conversion […]

Simple Gobar Gas Plant – Anaerobic Digestion Philosophy and Design

Biogas digesters make biogas, in other words, simple gobar gas plants make raw biomethane. What is biogas? Biogas typically refers to a gas produced by the biological breakdown of organic matter in the absence of oxygen. Organic waste such as dead plant and animal material, animal feces, and kitchen waste can be converted into a […]

A Beginners Guide to Biogas Digestate

Biogas digestate is the material left-over after the anaerobic digestion of an organic (carbon based material) feedstock. The anaerobic digestion process produces two primary outputs. These are biogas digestate (digestate) and biogas. Digestate is produced both at the start of the reaction, when inititial breakdown of the complex chemicals in each cell when alive is […]
