Abstract

The present invention relates to a method for the treatment of organic matter, in particular sewage sludge, where the organic matter is first fed to a disintegration system. The organic matter is then subjected to thermal hydrolysis in the disintegration system to form disintegrated matter. The disintegrated matter is fed to a digester in which the disintegrated matter is at least partially digested such that digested sludge is formed, where at least part of the digested sludge obtained is recirculated via a recirculation line to a point upstream of the disintegration system. The invention further relates to a device for the treatment of organic matter, in particular sewage sludge, comprising a disintegration system, a digester downstream thereof, and a recirculation line for at least partially digested disintegrated matter, said recirculation line extending from a point downstream of the digester to a point upstream of the thermal disintegration system.
