Biogas Plant flow process scheme
Biogas can be produced from different feedstocks. The main principal is that if the material contains biodegradable organic matter, under given conditions it shall be microbiologically transformed into biogas and mineralized compost.
In the following figure the process chain of modern biogas plant with its outputs is shown.
Table 1 demonstrates the typical energy balance of the biogas plant treating different raw materials such as municipal wastewater sludge, manure, and industrial waste. In the example case the biogas is 100 % used in CHP unit producing electricity and heat.
