<p>A system and method are provided for treating biodegradable waste material (16) in a landfill (12) by aerobic degradation. Waste material (16) is deposited in the landfill (12) and covered. The moisture content in the landfill (12) is increased from about 40 % to about 70 % and a source of oxygen is injected into the landfill (12) to drive and maintain primarily aerobic degradation of the waste material (16). The temperature in the landfill (12) is increased to substantially eliminate pathogens from the waste material (16). The temperature in the landfill (12) is controlled within a range of about 130 °F to about 150 °F to sustain the primarily aerobic degradation. Any combination of oxygen content, moisture content and temperature in the landfill (12) is monitored and varied to sustain and maintain the primarily aerobic degradation in the landfill (12).</p> |
