22. Manure becomes biogas, and then back to fertilizer
Gasum has some ten biogas facilities in Sweden. Three of them utilise manure, in combination with our residues from agriculture, in order to produce biogas. The carbon in the manure becomes biogas while the remaining nutrients become fertilizer that can go back to the fields. At our Katrineholm plant alone we produce 30 GWh biogas and 80 000 tonnes biofertilizer every year. In addition we also lower CO2 emissions with 13 000 tonnes.
