Abstract:
1. Method for the recycling of Municipal Solid Waste (M.S.W.), with minimal environmental impact and use of the Wasted Solid Recovered Fuel (W.S.R.F.), comprising the following steps: receiving M.S.W., mechanical sorting of dry and wet fractions, treating the dry fraction and preparation of WSRF, recovering metals, treating the wet fraction, refining a stabilized organic fraction, reducing the volume of bulky materials, treating process air gasifying the WSRF in a reactor with at least one combustion chamber, producing electric energy from gas derived from the process and/or producing hydrogen wherein the gasification of the WSRF comprises the steps of feeding continuously and homogeneously the WSRF into a reactor ( gasifying the WSRF by means of oxygen-biogas-burners, cleaning of the obtained gas, converting, by melting, the inorganic components present in the WSRF into vitrified non-leachable mineral and metallic granulate, wherein the biogas used by the burners derives from the process of anaerobic digestion of the organic fraction.
