Greenhouse Gas Reporting Program (GHGRP)

GHGRP 2011: Waste

The waste sector consists of municipal solid waste (MSW) landfills, industrial waste landfills, industrial wastewater treatment systems, and facilities that operate combustors or incinerators for the disposal of nonhazardous solid waste. Emissions from fossil fuel combustion at facilities with industrial waste landfills, and industrial wastewater treatment systems are included in other industrial sectors.

MSW landfills. The category consists of landfills that accepted MSW on or after January 1, 1980 and generated methane in amounts equivalent to 25,000 metric tons of CO2e or more per year. A MSW landfill comprises the landfill, landfill gas collection systems, and destruction devices for landfill gases (including flares).

Industrial Waste Landfills. The category consists of industrial waste landfills that accepted industrial waste on or after January 1, 1980 and that have a total landfill design capacity of 300,000 metric tons or more. The category excludes landfills for hazardous waste and those that receive only construction and demolition or inert wastes. An industrial waste landfill comprises the landfill, landfill gas collection systems, and destruction devices for landfill gases (including flares).

Industrial Wastewater Treatment. The category consists of anaerobic processes used to treat nonhazardous industrial wastewater and industrial wastewater treatment sludge at facilities that perform pulp and paper manufacturing, food processing, ethanol production, or petroleum refining.

Solid Waste Combustion. The category consists of combustors and incinerators for the disposal of nonhazardous solid waste.

Emissions from industrial waste landfills and industrial wastewater treatment systems were reported in 2011 but not in 2010. These emissions are included in the table above. Total emissions from these source categories in 2011 were 12.2 MMT CO2e.

CO2 emissions from the combustion of biomass are NOT included in emissions totals provided above.
