Denofa
The first production facility was located in Fredrikstad and was planned and constructed by Carl Fredrik Holmboe. The company merged with the soap company Lilleborg in 1960 to form DeNoFa Lilleborg. Later, it was demerged in 1996 to again form a separate company, but remained part of the Orkla Group. Denofa currently owns a production facility in Leknes, acquired after buying 100% of the company Marine Lipids.
