Method of converting waste material into fertilizer

Claim 1

THE METHOD OF CONVERTING ORGANIC WASTE MATERIAL INTO AN ORGANIC FERTILIZER, COMPRISING THE STEPS OF RECEIVING SAID WASTE MATERIAL IN A RECEIVING AREA, ADVANCING SAID WASTE MATERIAL FROM SAID RECEIVING AREA TO A GRINDING AREA AT A RATE NOT LESS THAN ABOUT THE RATE OF RECEIPT OF SAID WASTE MATERIAL IN SAID RECEIVING AREA THEREBY AVOIDING SUBSTANTIAL AGGLOMERATION OF SAID WASTE MATERIAL IN SAID RECEIVING AREA, GRINDING SAID WASTE MATERIAL DELIVERED TO SAID GRINDING AREA TO PRODUCE A GROUND PULP, ACCUMULATING SAID GROUND PULP IN A STORAGE ZONE, WITHDRAWING GROUND PULP FROM SAID STORAGE ZONE AT A RATE DEPENDENT ON THE FEED REQUIREMENTS OF A SUBSEQUENT DECOMPOSITION STEP AND INDEPENDENT OF SAID RATE OF ADVANCE OF SAID WASTE MATERIAL, DELIVERING SAID WITHDRAWN GROUND PULP TO A DIGESTION ZONE FORMED BY A PLURALITY OF ELONGATED SUPERPOSED STATIONARY SUPPORTING SURFACES, ADVANCING SAID DELIVERED GROUND PULP SUCCESIVELY ALONG SAID SURFACES IN A DIRECTION PARALLEL TO THE LENGTH THEREOF, MAINTAINING AIR SPACES ABOVE SAID GROUND PULP ON EACH OF SAID SURFACES, CONTINUALLY AGITATING SAID GROUND PULP WHILE ADVANCING THE SAME OVER SAID SURFACES TO PRESENT ALL PORTIONS OF SAID GROUND PULP REPEATEDLY TO THE AIR ABOVE SAID GROUND PULP WHEREBY SUBSTANTIALLY COMPLETE DECOMPOSITION OF SAID GROUND PULP OCCURS UNDER THE ACTION OF AEROBIC BACTERIA IN SAID GROUND PULP, PASSING AIR THROUGH THE SPACES ABOVE SAID GROUND PULP, THE VOLUME, TEMPERATURE AND RATE OF FLOW OF SAID AIR BEING SELECTED TO REMOVE SUBSTANTIALLY ALL VAPOR AND GASEOUS MATTER EVOLVED FROM SAID GROUND PULP AND TO ASSURE PROPER DECOMPOSITION OF SAID GROUND PULP, ADDING NITROGENOUS MATERIAL TO THE GROUND PULP IN SAID DIGESTION ZONE AT A POINT IN THE ADVANCE THEREOF OVER SAID SURFACES AT WHICH APPRECIABLE BUT NOT COMPLETE DECOMPOSITION OF SAID GROUND PULP HAS OCCURRED, SAID POINT BEING SELECTED TO AVOID CHEMICAL REACTION BETWEEN SAID NITROGENOUS MATERIAL AND SUBSTANTIALLY UNDECOMPOSED GROUND PULP, AND WITHDRAWING SAID GROUND PULP FROM SAID DIGESTION ZONE WHEN SAID GROUND PULP IS SUBSTANTIALLY COMPLETELY DECOMPOSED.

Claim 2

THE METHOD OF CONVERTING ORGANIC WASTE MATERIAL INTO AN ORGANIC FERTILIZER, COMPRISING THE STEPS OF RECEIVING SAID WASTE MATERIAL IN A RECEIVING AREA, ADVANCING SAID WASTE MATERIAL FROM SAID RECEIVING AREA TO A GRINDING AREA AT A RATE NOT LESS THAN ABOUT THE RATE OF RECEIPT OF SAID WASTE MATERIAL IN SAID RECEIVING AREA THEREBY AVOIDING SUBSTANTIAL AGGLOMERATION OF SAID WASTE MATERIAL IN SAID RECEIVING AREA, GRINDING SAID WASTE MATERIAL DELIVERED TO SAID GRINDING AREA TO PRODUCE A GROUND PULP, ACCUMULATING SAID GROUND PULP IN A STORAGE ZONE, WITHDRAWING GROUND PULP FROM SAID STORAGE ZONE AT A RATE DEPENDENT ON THE FEED REQUIREMENTS OF A SUBSEQUENT DECOMPOSITION STEP AND INDEPENDENT OF SAID RATE OF ADVANCE OF SAID WASTE MATERIAL, DELIVERING SAID WITHDRAWN GROUND PULP TO A DIGESTION ZONE FORMED BY A PLURALITY OF ELONGATED SUPERPOSED STATIONARY SUPPORTING SURFACES, ADVANCING SAID DELIVERED GROUND PULP SUCCESIVELY ALONG SAID SURFACES IN A DIRECTION PARALLEL TO THE LENGTH THEREOF, MAINTAINING AIR SPACES ABOVE SAID GROUND PULP ON EACH OF SAID SURFACES, CONTINUALLY AGITATING SAID GROUND PULP WHILE ADVANCING THE SAME OVER SAID SURFACES TO PRESENT ALL PORTIONS OF SAID GROUND PULP REPEATEDLY TO THE AIR ABOVE SAID GROUND PULP WHEREBY SUBSTANTIALLY COMPLETE DECOMPOSITION OF SAID GROUND PULP OCCURS UNDER THE ACTION OF AEROBIC BACTERIA IN SAID GROUND PULP, PASSING AIR THROUGH THE SPACES ABOVE SAID GROUND PULP, THE VOLUME, TEMPERATURE AND RATE OF FLOW OF SAID AIR BEING SELECTED TO REMOVE SUBSTANTIALLY ALL VAPOR AND GASEOUS MATTER EVOLVED FROM SAID GROUND PULP AND TO ASSURE PROPER DECOMPOSITION OF SAID GROUND PULP, ADDING NITROGENOUS MATERIAL TO THE GROUND PULP IN SAID DIGESTION ZONE AT A POINT IN THE ADVANCE THEREOF OVER SAID SURFACES AT WHICH APPRECIABLE BUT NOT COMPLETE DECOMPOSITION OF SAID GROUND PULP HAS OCCURRED, SAID POINT BEING SELECTED TO AVOID CHEMICAL REACTION BETWEEN SAID NITROGENOUS MATERIAL AND SUBSTANTIALLY UNDECOMPOSED GROUND PULP, AND WITHDRAWING SAID GROUND PULP FROM SAID DIGESTION ZONE WHEN SAID GROUND PULP IS SUBSTANTIALLY COMPLETELY DECOMPOSED.
