How is biogas produced - and from what?
Biogas is produced using organic material, which is broken down with the help of bacteria in an anaerobic (oxygen-free) environment. The anaerobic digestion process is a natural process that often occurs in nature. In a biogas plant, this process takes place in an anaerobic digester and is accelerated by creating the best possible conditions for micro-organisms and bacteria to multiply, which leads to a highly efficient breakdown of materials.
Almost all forms of organic material can be used to produce biogas. However, waste water, manure, energy crops and organic industrial waste are the most common feedstocks.
