Gasum invests to expand biogas plant in Finland
In Finland, Finnish energy company Gasum has decided to invest $ 8.08 million in a project aimed at expanding and enhancing the current biogas plant in Riihimäki, Finland.
Operational since 2016, the plant contributes around 45 gigawatt hours (GWh) of biomethane annually to the gas transmission network, meeting industrial and transportation needs for renewable energy, the firm said.
The project’s objective is to implement an advanced evaporation system to remove liquid more efficiently from the digestate generated during biogas production. This addition to the plant process not only boosts operational efficiency but also allows for the recovery of nitrogen in the form of valuable ammonium water, Gasum added.
“The plant primarily processes biowaste, sewage sludge and industrial side streams and the resulting digestate has traditionally been utilized in agriculture, providing essential nutrients to the farming as fertilizer. However, the utilization of digestate has faced challenges due to recently revised fertilizer regulations,” said Ari Suomilammi, Gasum’s Head of Renewable Gas.
