Biogas production in Rogaland

IVAR produces biogas based on sewage sludge, waste food and other organic waste. Biofuel plant for steam heat production based on de-watered bio residue and timber waste.

Methane gas emissions are a well-known problem from the perspective of climate change. Methane is 25 times more powerful as a greenhouse gas than CO2. Organic waste can be used as a source of energy instead of being composted, spread or left to rot. With 10% of Norway’s population, 20% of its livestock and organic waste from fisheries and other industry, Rogaland is very well placed to produce biogas. Local politicians decided to make the most of this by setting up a biogas plant in Grødaland.

The plant receives various types of sludge, food waste and organic waste. Biogas is produced from this and then refined and sold to Lyse AS. The CO2 that is extracted from the biogas is used as food for plants, and the bio residue is used as fertilizer and soil improver. This is the circular economy in practice. Biogas involves much more than the climate and environment – it also involves creating value and new jobs and making the most of resources!
