Our first bio-oil plant
95 % of the heat need in Joensuu is covered by CHP plant. Several heating stations cover the rest. Fortum's first bio-oil plant was integrated to Joensuu CHP in 2013. This fast pyrolysis technology-based bio-oil plant is first of its kind in the world on an industrial scale. Fortum Otso bio-oil is produced from wood-based raw materials like forest residues, wood chips and sawdust. Bio-oil can replace heavy or light fuel oil at heat plants or steam production. The plant uses biomass, peat and biogas as fuels.
