NOVELTY - Recovery and exploitation of a substratum of biomasses, municipal wastes and/or carbonaceous matrices for the co-production of bioenergy and products, involves: using algal and lignocellulosic biomasses for the production of vegetable organisms; feeding the substratum to a press-extrusion system; using the liquid organic fraction as feed for a biogas generation system; using the energetic dry fraction as feed for a synthesis gas generation system; wetland bio-filtering of obtained water; and using biogas and/or synthesis gas to feed vehicles.    USE - The method is useful for recovering and exploiting a substratum of biomasses municipal wastes and/or carbonaceous matrices for the co-production of bioenergy and products. The purified water obtained as by-product from the biogas and syngas generation system is used to irrigate open field cultivations and/or intensified greenhouses (all claimed).    ADVANTAGE - The method easily and efficiently recovers and exploits the substratum of biomasses, municipal wastes and/or carbonaceous matrices with high conversion rate in an economical and environmentally-friendly manner.    DETAILED DESCRIPTION - Recovery and exploitation of a substratum of biomasses, municipal wastes and/or carbonaceous matrices for the co-production of bioenergy and products by synergic integration of different conversion processes and treatment of the emissions in closed-loop circuit, involves: using algal and lignocellulosic biomasses deriving from the exploitation of the by-products generated by primary conversion systems such as thermal and electric energy, digestate, biochar, water, carbon dioxide and nitrogenous and sulfurized compounds and ashes as nutrients for the production of vegetable organisms by intensifying the photosynthesis processes for the treatment of emissions and the sequestration of carbon dioxide; feeding the substratum to a press-extrusion system, provided of separation means, so that it is sub-divided into a liquid organic fraction and an energetic dry fraction; using the liquid organic fraction as feed for a biogas generation system by bacterial fermentation under anaerobic conditions; using the energetic dry fraction as feed for a synthesis gas generation system by a thermo-chemical conversion; wetland bio-filtering water obtained as by-product from the biogas and syngas generation system, obtaining purified water and primary biomass; and using biogas and/or synthesis gas produced by a co-generation system and/or biofuels deriving from biogas and/or synthesis gas to feed vehicles. An INDEPENDENT CLAIM is included for a gas flow enriched with carbon dioxide derived from fumes which are a by-product of primary conversion systems sent to greenhouses as air-conditioner for the intensification of the photo-synthesis of cultivations, preferably flowers and algal biomass subjected to cycles of artificial lighting, where the greenhouses are thermally controlled.
