Potential Biowaste: 

WORKSHOP WATER AND AIR Potential Biowaste 10 Fachverband Biogas e.V. German Biogas Association • Asociación Alemana de Biogas • Société Allemande du Biogaz Biowaste accumulation in Germany: 91,4 kg / inhabitant * year Biogas Potential : ~ 100 m³ / t biowaste Electrical Potential : 1,5 – 3 kWhel / m³ Biogas = 91,4 * 0,1 * 2,5 = 22,85 kWhel / inhbitant * year = 80.000.000 * 22,85 = 1.828 GWhel / year in Germany (Agricultural, commercial & industrial waste is not included)

Biogas – the all-rounder: 

WORKSHOP WATER AND AIR Biogas – the all-rounder 11 Fachverband Biogas e.V. German Biogas Association • Asociación Alemana de Biogas • Société Allemande du Biogaz The biogas is burned in combined heat and power units (CHP) to produce electricity. Beside the CHP produce heat as a by-product. With the biogas from a hectare maize silage drives a natural gas car approximately 70,000 kilometres The „biogas potential“ in Germany can replace up to 20 % of the German natural gas consumption Biogas electricity heat fuel natural gas grid storage electricity heat fuel natural gas grid storage
