Nutrient recycling by using residues from forest industry

Abstract

A major part of residues from pulp industry are deposited as waste at high disposal costs. This
paper summarizes a five-year research project concerning implementation of an industrial,
automatic roll-pelletizing method at a heating plant in the city of Kalmar, Sweden and presents
the visions of the newly initiated research project where pulp industry residues are recycled
together with wood ash. Also combustion issues are included.
