A roofing ceremony was held last week at Metsäsairila waste management site in Mikkeli. This builders’ rite marked an important milestone of the construction of BioSairila’s biorefinery plant supplied by BioGTS, which is scheduled to be in operation in the first half of 2019.


At full capacity, the biorefinery plant provides treatment to digest approximately 19,500 tons of municipal and agricultural biomass per year for the production of biogas and fertilizer products. The biogas that is produced from the process will be upgraded to biomethane, and mainly utilized as commercial transportation fuel. The biorefinery plant promotes emission-free driving in the area of Mikkeli, at full capacity, the biogas production capacity corresponds to the annual fuel consumption of more than 1,000 passenger cars.
