Biogas

Biogas is an energy source that is obtained regionally from renewable raw materials. In addition to liquid manure and green waste, this also includes renewable energy crops. The regenerative gas is produced as a result of fermentation processes of the ‘green raw materials’ in various stages of the biogas plant. The resulting combustible gas is collected and can be utilised. 
The main reason for producing and utilising biogas is to use a regenerative or renewable energy source. Historically, however, until the end of the 20th century, fossil fuels were too cheap to arouse interest in biogas. It was only as a result of the energy and oil crises that this type of energy generation became increasingly important. With the help of political decisions such as the Electricity Feed-in Act and the Renewable Energy Sources Act (EEG) from 1991, the course was finally set for the worthwhile production of biogas, in which it was remunerated separately.
