Abstract:
A method for accelerated biodegradation of organic matter, said method comprising the steps of:(a) substantially enclosing a stack of organic matter, the stack having a top side, a bottom side, and a pair of outer sides;(b) introducing a gas having an oxygen content of between 10% to 18% and a temperature of between 30.degree. C. to 45.degree. C. to the bottom side of the stack;(c) circulating the gas containing oxygen through the stack;(d) collecting the gas after it exits the stack;(e) cooling the gas to a temperature of between about 30.degree. C. to 45.degree. C. and adjusting the oxygen content to between 10% to 18% prior to recirculating the gas to the bottom side of the stack in a substantially closed loop system;(f) adjusting the recirculation rate and the amount of cooling of the gas to establish and maintain a temperature gradient between the bottom side and the top side and outer sides within the stack with a lower temperature at a gas input in the bottom side and a higher temperature at the top side and the outer sides of the stack; and(g) agitating the organic material in the stack periodically.
