TECHNOLOGY FOCUS - ENVIRONMENT - Preferred Method: The step of receiving municipal solid waste is performed using a feeder line with mechanical sorting device, which after weighing, removes any bulky materials. The mechanical sorting of the dry and wet fractions occurs through the screening grates of rotating trommels with self-cleaning device, after performing the plastic refuse bags-opening by slow-rotation bag-splitters. The treatment of the dry fraction and preparation of the WSRF involves removal of the metallic items, sizing by a shredder with extendable grating, wind sifting, and cleaning and quality enhancement. The recovery of the metals involves using electromagnetic and eddy currents actions. The treatment of the wet fraction is an aerobic consisting of a bio-oxidation comprising accelerated decomposition of the organic substances for 2-3 weeks, separation of the inert processing residues from the bio-mass, and maturation and stabilization of the organic fraction for 5-6 weeks. The bio-oxidation is maintained aerobic using forced mechanical overturning. The forced aeration occurs by a capillary air distribution network, while the mechanical overturning is obtained by screw augers. The refining of the stabilized organic fraction is achieved on a mechanic line where inert fragments like glass and stones are rejected and WSRF mainly consisting of plastic fragments and stabilized organic fraction are obtained. The volume reduction of the bulky materials occurs by shredding and contemporary recovery of the ferrous materials. The process air treatment comprises suction of air from every process stage and maintenance of negative-pressure conditions, and sending part of the sucked air to the combustion cycles of the WSRF and the rest to an air treatment system. The gasification of the WSRF comprises feeding continuously and homogeneously the WSRF into the reactor, gasification of the WSRF by oxygen-biogas-burners (11), cleaning of the obtained gas, conversion by melting the inorganic components present in the WSRF into vitrified non-leachable mineral and metallic granulate. The biogas used by the burners derives from the process of anaerobic digestion of the organic fraction. The gas coming from the upper part of the reactor undergoes quenching with water, acid washing, basic washing, initial elimination of sulfuric acid, elimination of fine particulate by wet electrostatic filter, catalysis for the elimination of the organic compounds of sulfur, and elimination of the residual sulfuric acid. Preferred Condition: The reactor and the gas treatment stages operate in a slight over-pressure condition at the pressure of up to 450 bar. The carbonious fraction of the WSRF falls into a crucible in the lower part (9) of the reactor where the temperature is 1500-1700 (preferably 1600)degreesC, and gasified after the volatile fraction. The temperature of the gasses exiting the reactor comprises 800-1200 (preferably 1100)degreesC.    TECHNOLOGY FOCUS - MECHANICAL ENGINEERING - Preferred Component: The system for the continuous and homogeneous feeding of WSRF comprises a WSRF storage silo, a conveyance system of the WSRF from the storage silo to a dosing receiver, conveyance system of the WSRF from the dosing receiver to an inlet system into the gasification reactor, a double sealing system with valves, an inertization system with nitrogen, a conveyance system for feeding the WSRF into the gasification reactor, and an excessive capacity recovery system. The reactor comprises an upper part and a lower part provided with a melting crucible. The granulate collection tank is connected to the crucible by a channel. The section for the elimination of fine particulate comprises a wet electrofilter. An hydraulic guard directly connected to an emergency flare is provided between the section for the elimination of fine particulate and the catalyst for the elimination of the organic compounds of sulfur. The system for the production of electric energy comprises gas turbines and engines. The system for the production of hydrogen comprises a carbon monoxide clean-up unit, membranes separation unit, pressure swing adsorption unit, hydrogen compression, and storage unit.
