Gasum plans to upgrade the biogas into Liquefied Biogas (LBG) and sell it as fuel for cars, buses, trucks, and ferries. The expected LBG production of the plant is 75-90 GWh per year.

Stora Enso and energy company Gasum have signed a contract to build a biogas plant at Stora Enso’s Nymölla paper mill in Sweden. The plant, built and operated by Gasum, will turn the mill’s wastewater effluent into renewable energy.

Gasum plans to upgrade the biogas into Liquefied Biogas (LBG) and sell it as fuel for cars, buses, trucks, and ferries. The expected LBG production of the plant is 75-90 GWh per year, equivalent to the amount of fuel needed annually for more than 200 average long haul lorries in Sweden. Production is expected to start during 2020.

The total investment of the project for Gasum is around EUR 27 million and for Stora Enso around EUR 5 million. Gasum has been granted an investment subsidy of SEK 121.5 million (EUR 12.7 million) by the Swedish Environmental Protection Agency under the Climate Leap (‘Klimatklivet’) programme.

Located in southern Sweden, Stora Enso’s Nymölla Mill has an annual production capacity of 340 000 tonnes pulp and 485 000 tonnes woodfree uncoated (WFU) paper for office and postal use. Stora Enso’s well-known office paper brand Multicopy is produced in Nymölla.
