Apr 14, 2016. /Lesprom Network/. Fiskeby’s biogas plant converts cellulose and starch in the paper recycling waste water to high-quality methane. The plant started in August 2015 and has been running well since the start. The waste water is particularly well suited for gas production, as the company said in the press release received by Lesprom Network.

The heart of the biogas plant is the IC reactor containing a fixed bed of gas-producing bacterial sludge pellets, called granules. These convert cellulose residues in the process waste water to climate neutral gas.

Fiskeby’s biogas plant thus creates several values ​​from the process waste water. Partly in the form of the energy contained in the biogas, partly by offloading the existing water treatment plant and finally by helping other biogas plants with sludge.

Fiskeby manufactures paper and board.
