Liquefied biogas has enormous potential in decarbonising the transport sector, both on land and at sea. Gasum is determined to deliver for the Nordics.
In the Nordics, Gasum has been working hard to deliver an extensive network of liquefied biogas (LBG) filling stations and decarbonise transport in the region. In the maritime sector, the company supported ESL Shipping in becoming the first in Finland to use 100% renewable LBG in maritime transport. Multiple bus fleets have introduced biogas-fuelled buses with Gasum’s support, and it shows no signs of slowing down.
Most recently, the company has been working on a major project at the site of Stora Enso’s Nymölla paper mill in Sweden. The project is based on wastewater from pulp and paper production.
On the way to the mill’s external wastewater treatment plant (WWTP), the facility’s wastewater streams are collected in settling tanks. Instead of being pumped directly into the WWTP, the wastewater is pumped into Gasum’s high-rate bioreactors, where the organic content is reduced by approximately 60% and biogas is produced.
