Abstract
Sludge having a water content of less than 60% by weight is obtained by disintegrating primary dewatered sludge in a disintegrator to form sludge pieces having a layer of a dry dewatering additive while preventing the sludge from becoming like a slurry and then compressing the sludge pieces. The sludge thus obtained is combustible without requiring any further fuel.
