Detailed Information

Name of the company: Greve Biogass AS

Country: Norway

Size of the business: 12 employees



Greve Biogas is a partnership established by 11 different municipalities in the Western region of Oslo-fjord. The story of the company started in 2008, and then, on one hand, the local politicians wanted to do something regarding green sector, and on the other hand, the farmers in the region had problems with too much manure. Thus, the establishment of Greve Biogass provided an opportunity to address both issues and keep up the agricultural production, while using the manure and agricultural residues for biogas production. It was decided that all public transport (buses in the region) should be fuelled by biogas and thus a market was established.
