Norsep AS

Norsep AS is a spin-off from OiW Process AS that was created to develop and commercialize the Norsep-process. This is a process for rendering fly ash from incineration of household waste harmless through leaching of heavy metals in hydrochloric acid, followed by filtration and then heat treatment. Process development has been ongoing since 2015, and Norsep is now ready to take the next step, which is the engineering, construction and operation of a facility with the capacity to process 2,000 tonnes of fly ash per year. Norsep AS also works with the development of processes for the treatment of other waste streams.
