1. Method of treating mainly decomposable, solid and liquid wastes, such as garbage and biologically active sludge, in which the solid wastes are disintegrated and then mixed with the sludge and thereafter the waste-sludge mixture is processed into pressed blocks or slabs, characterized in that a) fresh sludge or a sludge mixture of partly fresh and partly rotting sludge - first sludge - is oxidized in known manner in a vessel as far as the first unstable equilibrium of the bacterial decomposition of the sludge, b) then the thus treated sludge or a sludge mixture of partly rotting and partly oxidized sludge - second sludge - is mixed in finely distributed manner with the disintegrated solid wastes, c) then the waste-sludge mixture, for improved reticulation and mutual interpenetration of the solid wast and of the sludge, is subjected to slab type pressing under alternating pressure and expansion and the waste-sludge mixture, issuing in the form of pressed slabs arranged in succession compactly or as a strand from the pressing apparatus, is expanded and rendered permeable in predetermined manner for gas and water exchange by partial relieving of the pressing pressure.
