Abstract
A method for composting organic waste materials utilizing aerobic and anaerobic decomposition processes simultaneously is disclosed. The method of the present invention is carried out by forming a compost pile of organic waste material which will decompose aerobically by microbes indigenous to the waste material. A cavity of predetermined size is formed within the compost heap and filled with alternating layers of organic waste material which will decompose anaerobically followed by a layer of waste material which will decompose aerobically until the cavity is filled. The parameters of the decomposition processes including temperature, water content, aeration, and moisture percolation are monitored to ensure that adequate conditions are met for both decomposition processes to proceed simultaneously. After a predetermined time interval has passed, the organic waste materials deposited within the central cavity of the compost heap are harvested to obtain a nutrient rich, soil additive. Thereafter, the central cavity is refilled with alternating layers of organic waste material and the decomposition cycle is repeated. The composting method of the present invention is adaptable to a wi…
