The biogas plant of Lakeuden Etappi started operating in 2007. It is one of the largest biogas plants in Finland.

The biogas plant uses municipal sludge and biowaste to produce biogas and RANU fertilizer by drying digested sludge first by using a centrifuge, then through a thermal method and, finally, by compressing it into pellets.

In addition to sludge from municipal purification plants, the plant processes biowaste produced by households and companies, and the food waste of shops and restaurants. The service is also offered to the food industry. Every load must include a commercial document.

The biogas produced is used in the first stage to run the process and power up the plant. Extra biogas is burned in a flame.
