ABSTRACT The present invention relates to a process for the valorization of solid wastes, comprising at least 30% by weight of cellulosic materials, in particular household refuse; the said process including the preliminary steps of grinding and sorting the said wastes in order to remove metallic elements from them. The said process consists of thermally treating - in a tubular reactor (13) equipped with an Archimedean screw (24) and heated by the injection of hot combustion gases at its entrance, the said reactor being maintained under a slight partial vacuum - a mixture of a homogeneous mass containing the said shredded wastes and mineral products, the said mixture containing in particular quick lime, calcium carbonate, and caustic soda; the said thermal treatment and the introduction of the said minerals ensuring a rise in temperature of the said mixture in the first part of the reactor sufficient to produce an intense luminous radiation. The invention also relates to a device for the implementation of the said process. Fig. 2
