Abstract

The invention relates to an improved continuous process for the exploitation of cellulose production process wastes. The process comprises the following operations: a) the said process waste is fed into a pyrolysis reactor and is pyrolyzed therein by heating the process waste with a residence time of 0.1-100 s at a temperature of 300-700 DEG C into a pyrolysis product which comprises a liquid fuel, a gaseous fuel and a solid residue, b) the pyrolysis product is fed into a separator, wherein the solid residue is separated from the liquid and gaseous fuels, c) the liquid and gaseous fuels are recovered, and d) the solid residue is fed into a combustion vessel, wherein it is burned to generate heat. The invention also relates to an apparatus for carrying out such a process.
