About this site

The anaerobic digestion process produces gas composed of methane (CH4) and carbon dioxide (CO2), known as biogas. These gases are produced from organic wastes such as livestock manure, food processing waste, etc. Anaerobic processes occur using organic wastes and various types of bacteria by placing them in an airtight container called a digester.

Biogas Anaerobic Digestion

Dec 15, 2020  Biogas is the primary useful product produced by the anaerobic digestion (AD) process. It is similar to natural gas, in that it is largely made up of methane, being about 50-70% methane and 25-45% carbon dioxide (CO 2), along with some impurities.. Biogas is usually burned locally to the AD plant, to produce electricity and/or heat.

Anaerobic Digestion Plants

Anaerobic Digestion Plants processing dedicated energy crops can work well, and the best examples achieve very high levels of organic content degradation and biogas production. However, in most countries, subsidies for these crop-only fed plants are being phased out, due to concerns that they compete with crop used for food, and raise food prices.

The fact that a combustible methane gas is produced from anaerobic digestion of biological material was recognized by Von Helmont in 1630, Shirley in 1667, Volta in 1776, Priestly in 1790, and Dalton in 1804. Laboratory experiments to produce methane from manure were made in 1806 by Humphrey Davy.
