Energy
The waste fractions from a waste incineration plant consist of fly ash, filter cakes, gypsum and bottom ash, which contain heavy metals and other pollutants. NOAH has developed a unique treatment method for these waste fractions.
Energy waste
NOAH receives large amounts of sulfuric acid, which, when mixed with ash fractions, forms a gypsum. This plaster is used as a building material for the rehabilitation of Langøya. This process, where two wastes are used to neutralize each other and the end product becomes a building material, is classified by the authorities in all northern European countries (except Sweden) as an R-process (recovery).
NOAH's customers can thereby refer to a form of treatment for their waste, which has a recycling status.
Ash fractions are received from all over northern Europe and currently amount to more than 300 tonnes per year.
