<p>The present invention regards a chemical-physical process fertilizer production from organic waste, catalyzed by a catalyst composed by salts and organometallic complexes of transition metals in which the humid organic wastes, opportunely smashed in pieces of millimetrical dimensions, are shaked by means of opportune movement systems in presence of said catalyst up to the moment in which the water content present in the reacting mass becomes inferior to determined fractions of global mass. The invention regards also the production plant of said process characterized by the presence of at least: a) mills for the materials smashing; b) a feeding device of the reaction chambers which permits the balancing of different types of wastes so that the produced fertilizer obtains assigned chemical compositions; c) one or more than one reaction chambers in which the reacting mass can be opportunely shaked in order to favour the continuous mixing of the material and the fixing of the equal reaction conditions in the entire mass of reacting material; d) a sieve for the separation of plastic, glass or other undesirable materials with dimensions superior to those of produced fertilizer; e) devices for the heating and circulation of hot liquids acted to maintain the conditions of temperature settled for the best conduction of the processes; f) devices for the refrigeration and circulation of cold liquids acted to condense the water vapours eliminated during the drying process; g) traps for the reduction of gas emissions from the reaction environment; h) devices for gathering and bagging of produced fertilizer; i) wastes moving devices; 1) automation and process conditions control devices.</p> |
