Process for eliminating organic matter and for generating energy

Abstract

Process for destroying organic matter, in which said organic matter in ground form is introduced into a reactor and subjected to flameless combustion at a temperature of 240 to 400° C. under a pressure of 100 to 300 bar, in the presence of an oxygen-containing oxidizer for at least 20 minutes, while stirring the medium, and process for generating energy, in which the energy generated by the combustion is furthermore recovered.
