“We are systematically expanding and strengthening our industrial ecosystem in Äänekoski. It is important that we own some of the operations, while others are based on partnerships. Through this acquisition, we will be able to make even more efficient use of the biogas plant as part of the bioproduct mill process. The wastewater sludge from the bioproduct mill will be converted into added-value products in the biogas plant,” says Ismo Nousiainen, CEO of Metsä Fibre.
“We built and started up the biogas plant in 2017, based on technology developed by Envor Group. Together with Metsä Fibre, we now felt it was best to transfer the operation and ownership of the plant to Metsä Fibre as part of the bioproduct mill’s ecosystem,” says CEO Tero Mäki, EcoEnergy Oy.
In addition to treating the sludge from the bioproduct mill, the biogas plant processes sludge from Äänekosken Energia’s wastewater treatment plant and other biodegradable sludge generated in the mill area.
