The plant for the thermal treatment of material, in particular scrap material, comprises at least a reaction zone (10, 10a, 10b, 10c) within a rotary kiln (12) having the longitudinal axis inclined of an angle in the range 0°±45° with regard to an horizontal plane and provided of first heating means (14) and of at least a rotary screw (16) having second heating means (18). The screw shaft (20) is hollow and has, at least locally, apertures allowing the flow of gas from and/or into the reaction zone (10, 10a, 10b, 10c), a plurality of thermally conductive particles being movable within the reaction zone (10, 10a, 10b, 10c).
