Process for converting organic waste to humus

Abstract

Abstract A CONTINUOUS PROCESS OF COMPOSITING ORGANIC WASTE MATERIAL WHILE MAINTAINING A PH RANGING BETWEEN 6 AND 8, A MOISTURE CONTENT RANGING BETWEEN 40 AND 70%, AND A TEMPERATURE MAXIMUM OF NOT MORE THAN 65*C., THE PROCESS CONSISTING OF THE STEPS OF (A) FORMING A CENTRALLY DISPOSED SUBMERGED AIR SPACE WITHIN AND SUBSTANTIALLY INTERFACIALLY SURROUNDED BY A STATIONARY MASS OF SAID MATERIAL, (B) MAINTAINING EQUALIZED AIR PRESSURE IN THE SPACE CONCURRENTLY WITH SPRAYING SAID AIR THERFROM AT A UNIFORM VELOCITY INTO THE MASS JETS UNIFORMLY DISTRIBUTED OVER SAID INTERFACE TO THEREBY AERATE THE MATERIAL, PROVIDE OXYGEN FOR AEROBIC COMPOSITING, AND PREVENT A TEMPERATURE RISE ABOVE SAID MAXIMUM, (C) CONTINUING THE AREATION UNTIL MOST OF THE AVAILABLE NUTRIENTS FOR MULTIPLYING HEAT-PRODUCING THERMOPHILIC AND MESOPHILIC BACTERIA HAVE BEEN UTILIZED TO CAUSE THE TEMPERATURE TO FALL SUBSTANTIALLY, AND TO A LEVEL WHICH, WHEN INOCULATED WITH BENEFICIAL SOIL CULTUERS CONSISTING OF STREPHTOMYCES, AZOTOBACTER AND RHIZOBIUM AND OTHER BENEFICIAL SOIL ORGANISMS, THE TEMPERATURE OF THE HUMUS WILL ALLOW THE CULTURES TO MULTIPLY AND BECOME AN INTEGRAL PART THEREOF, AND (D) RECYLING A PORTION OF THE FINAL STABILIZED HUMUS OF WHICH THE SOIL CULTURES HAVE BECOME AN INTEGRAL PART TO A POINT IN THE CONTINUOUS PROCESS WHICH WILL ALLOW THE CULTURES TO GROW TO AN EVEN HIGHER CONCENTRATION.
