Coprocessing of industrial wastes and rural organic residues by hydrothermal treatmen

Abstract : Annual production of European industrial wastes is about one billion tons. On the other hand, intensive farming and important urban centers generate large quantities of liquid manure or sanitary organic wastes. These wastes are a threat for the soil and water resources. The cost of their individual waste disposal or treatment decreases the competitiveness of enterprises and limits the development of rural areas. Coprocessing of these wastes is possible using the VarTech® reactor. The operating conditions of this reactor are about 250 to 300°C and 120 to 150 atmospheres. These conditions allow the decomposition of the organic wastes and the reduction of solid industrial ones thus eliminating both with a reasonable economic cost. The coprocessing of the jarosite and these organic wastes was successfully tested. This new approach can be extended to a wide variety of industrial solid wastes and organic residues
