Abstract

Disclosed is a bio-thermal treatment of refuse with organic constituents in a tank, consisting in withdrawing the outgoing air from the tank and then reintroducing it into the tank. In order to improve the process, the invention suggests that the outgoing air be heated before being reintroduced into the tank.
