With a total of 60,000 m3 digester capacity at its three treatment plants, Denmark’s largest wastewater company, BIOFOS, was able
to reach a 173% surplus on green energy production in 2019.
By increasing the energy surplus, BIOFOS has been able to increase the supply of green energy to the City of Copenhagen’s ‘city-gas‘ network as well as the natural gas network, thereby reducing CO2 emissions produced by traditional methods of gas production. In addition, the surplus of heat from the incineration of digested sludge supplies the district heating network in Greater Copenhagen. With a constant growth in green energy production, BIOFOS’ energy balance has been positive since 2014. As a result, BIOFOS aims to become a climate positive treatment company by 2025. In addition to increasing its own green energy production, BIOFOS also focuses on reducing its purchase of fossil fuel based energy from the public grid and as well as reducing emissions of greenhouse gas emissions from the wastewater treatment processes – especially from the potent nitrous oxide (N20).
