Biogas

Biogas arises from microorganisms at the reduction of organic substance under exclusion of oxygen. The process also is called Fermentation. It takes place everywhere in nature, parallel to the biological degradation. At the biological degradation, also called gang, the organic substance is dismantled by oxygen loving microorganisms. Fermentation and gang are the essential mechanisms of the carbon circulation in nature.

Biogas consists of 65% Methane. The rest is Carbon dioxide and other gases. If the gas is burned, the energy content corresponds to that which was originally stored by photosynthesis in the plants.

 

 

So a natural process is grown in a biogas plant by being offered optimal conditions to the involved microorganisms. In this optimal environment the bacteria then spread solidly and produce the biogas at the reduction of the organic substance.

The sources' of energy biogas is regenerative, CO2 neutrally and, as long as the sun is shining, inexhaustibly.

 

Biomass catalog

Typical organic waste which can be utilized in a biogas plant is listed in the following list.

To utilize different substances in the mix, it is necessary to know the possible ratios of a mixture. It doesn't come to any optimal gas gain at wrong ratios of a mixture.
