Gasum has delivered the first liquefied biogas (LBG) shipment to its customer Essity, a Swedish hygiene and health company.
Already a liquefied natural gas (LNG) customer, Essity will now test renewable LBG to make its operations and products completely fossil-free. By replacing natural gas with biogas, Essity’s tissue production facility in Lilla Edet will become emission-free during normal operations and reduce its CO2 emissions to zero.
“We are very pleased that Essity has made the decision to take a step from LNG to LBG, which is an excellent choice when pursuing a fossil-free production process,” said Tommy Mattila, Gasum’s vice president.
“We constantly aim to provide our industry customers with a unique and competitive offering, which will help them in transitioning towards more sustainable sources of energy.”
The production facility in Lilla Edet has constantly developed its production process to meet Essity’s high sustainability ambitions. Recycled paper is used as a raw material and recycled fibre sludge, and collected recycled wood is used to produce steam in the solid fuel boiler, where the paper is dried.
During normal operation, the solid fuel boiler has no fossil CO2 emissions. The steam is also distributed via a district heating network to the local community to provide heat.
In the final production step, hot air caps are used to dry the paper. These are heated with gas burners powered by LNG, however, the tests currently being carried out mean that the natural gas will be completely replaced by LBG.
Christian Carlsson, factory manager at Edet Mill, Essity, said: “We continually evaluate our production methods. The planning has been going on for a long time and in January we carried out the first tests, with good results. We are now launching full-scale tests with the target of becoming the world’s first tissue production plant free of fossil CO2 emissions by 2021.
“The ambition is to share our experiences with our other production facilities and together contribute to achieving our ambitious climate goals. We want to continue to break barriers to health and wellbeing by offering innovative and sustainable hygiene and health products.”
