What is biogas?
Biogas is a source of energy produced through anaerobic fermentation of various types of organic matter. This process is also known as anaerobic digestion and is carried out by the microbial communities put under certain conditions.
The generated gas is made of methane (CH4), carbon dioxide (CO2) and trace elements of other gases, hydrogen sulphide (H2S) being one of them.
Anaerobic digestion also generates a type of digestate that is rich in nutrients (N, P, K, Ca, etc.) and organic matter that has lower levels of odours and whose main field of application is agriculture, where it is used as mineral fertiliser for crops
