Sludge commoditisation – development of a concept for refining sludge to a commercial product

This project will verify the potential of a new innovation based concept for increased utilization of sludge produced at the Norrmejerier biogas plant in Umeå. The sludge is dried and pasteurized in a high velocity cyclone drier and is further refined through compaction into a storable and easy handled material. New environmentally friendly flocculant chemicals will be used to meet the requirements for certification and use on farmland
