Fish Food from Pulping Liquors

Nordic Paper's paper mill in Säffle, Sweden, reportedly is investigating the production of fish food as a product refined from its spent sulfite cooking liquor. The mill has partnered with Cewatech, a Sweden-based biotech company to help it debvelop the new product. The mill's Eva Pettersson explains that the sulfite liquor contains high volumes of sugars that can be refined into a fungus biomass, which in turn can be converted to environmentally friendly fish food using Cewatech technology. A pilot plant will be built in Säffle to help take the project into commercial operation. Vinnova, a Swedish Government development authority, will contribute some 2.5 million Kronor to the project. The Säffle mill produces 50,000 metric tpy of sulfite pulp used in the production of 30,000 metric tpy of greaseproof paper with two paper machines.
