  • Method and system for controlling biodegradation and temperature in an aerobic or anaerobic subsurface or partially enclosed waste mass
    Publication number: 20100032371
    Abstract: This invention is a new and useful method for controlling the temperature and biodegradation rate of an anaerobic or aerobic landfill or other enclosed or partially enclosed waste mass. The heat generated by a waste mass is carried away by air and moisture within the air resulting from evaporation of liquid within the waste mass as air passes through the waste mass. With the invention, the resulting exhaust gases are passed through a system acting as a heat exchanger and an exhaust gas director.
