By expanding the energy surplus, BIOFOS increased the supply of green energy to the City of Copenhagen’s ‘city-gas‘ network and natural gas network. By doing so, the CO2 emissions produced by traditional methods of gas production was reduced. In addition, the district heating network in Greater Copenhagen are supplied with surplus heat from the incineration of digested sludge .

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, BIOFOS focuses on reducing both its purchase of fossil fuel based energy from the public grid, as well as emissions of greenhouse gas emissions from the wastewater treatment processes – especially from the potent nitrous oxide (N20).
