Abstract
Uncontrolled anaerobic bioreduction in landfills is a slow metabolic process that generates high levels of methane and trace amounts of other noxious gases. To determine the potential for using leachate recirculation and air injection as a means for converting anaerobic processes to more rapid aerobic processes, and to significantly reduce production of methane, a ±2.5 acre, 70000 yd ³ cell within a sanitary municipal solid waste landfill located near Atlanta, Georgia was selected as a test site where methane was used as the primary parameter indicating associative aerobic/anaerobic activity levels. Results indicate significant decreases in initial methane and CO₂ levels from 46% and 54% to averages of 10% and 20% respectively. Temperatures for the more exothermic aerobic reactions were kept under control through leachate recirculation while leachate quality was not negatively impacted. Respirometry data on bulk material indicated a high percentage of inert, high quality compost-like material after 10 months.
