Stora Enso and Gasum to make renewable energy from wastewater in Sweden
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 to 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.
‘We are happy to be part of a project that will turn waste into valuable renewable energy,’ said Michael Lindemann, mill director at Nymölla Mill. ‘For Stora Enso, substituting fossil based fuels in our society with renewable solutions is a vital way to combat global warming. The cooperation with Gasum is a good example of the collaborative efforts Stora Enso is taking to do this.’
‘We are pleased about the circular economy cooperation with Stora Enso. The biogas plant is a sustainable solution for the processing of wastewater. Gasum is actively building a gas ecosystem for industry, marine and road transport segment in the Nordics,’ said Johanna Lamminen, chief executive officer of Gasum.
The total investment of the project for Gasum is around €27 million and for Stora Enso around €5 million. Gasum has been granted an investment subsidy of SEK121.5 million (€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.
