The invention concerns a plant for the thermolysis of waste products containing an organic fraction, and for simultaneous energetically upgrading these waste products comprising: a unit for loading and supplying the waste products to be treated; a thermolysis reactor for thermal dissociation under reduced pressure at high temperature. The invention is characterized in that it comprises: upstream and downstream of the reactor, a lock chamber for maintaining a partial vacuum in the reactor for ensuring thermolysis in an atmosphere with low oxygen content; first means for recuperating, in the upper part of the reactor, the organic gas fraction formed during thermolysis, and for bringing this fraction to a combustion chamber supplying a steam generator; second means for recuperating at the bottom of the reactor the solid carbon products formed during thermolysis, and for bringing these solid products to a combustion chamber supplying a steam generator or an evacuating system. The gas of the combustion chamber and the steam produced by the steam generator, in turn supply the unit producing the waste products and/or means for drying in advance of the waste products provided just upstream of the reactor.

[ What is claimed is:] [1.]1. Plant for the destruction by thermolysis of meat meal (2) and the combustion of the meal to produce steam that includes:a unit for the production (1) of meat meal from animal carcasses;a continuous feed isolation means (5) and a gravity hopper (4) for feeding the meal produced to a reactor;said reactor for the thermolysis (13) of the meal thus produced;means (15,16) for recovering, at the top of the reactor (13), the gaseous organic fraction formed during the thermolysis and for introducing this gaseous fraction into a first combustion chamber (20) feeding a first steam generator (22);means (11) for recovering, at the bottom of the reactor (13), the solid carbonaceous residues formed during the thermolysis and for introducing these solid residues into a second combustion chamber (60) in its turn feeding a second steam generator (65);said two steam generators (22, 65) in turn feeding energy to the unit for the production (1) of meat meal.
