ABSTRACT:
A carbonaceous material and a nitrogenous material are mixed in combination with activated carbon ash and perlite fines. The activated carbon and perlite fines serve to limit the loss of ammonia nitrates as well as to lock nitrogen in the biomass and to limit fly larva and odors. The nitrogenous material comprises fish scrap and the carbonaceous material may include wood sawdust, wood pulp or agricultural by-products. All of the ingredients of the product may comprise industrial waste products. The process is conducive to forming large batches of the process comprising depositing an elongated windrow on the ground and making a full length groove in the top surface. The activated carbon and perlite dust are then layered in the groove and the nitrogenous material deposited on the activated carbon and perlite dust. The ingredients are mixed under selected moisture and temperature conditions to form the end product.
