Greenhouse Gas Reporting Program (GHGRP)

GHGRP 2012: 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 sectors.

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

Industrial Waste Landfills. This 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. This category includes emissions from the landfill, landfill gas collection systems, and destruction devices for landfill gases (including flares).

Industrial Wastewater Treatment. This 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. This category consists of combustors and incinerators for the disposal of nonhazardous solid waste.

Totals may not equal sum of individual GHGs due to independent rounding.

Emissions from industrial waste landfills and industrial wastewater treatment systems were reported beginning in 2011. These emissions are included in the table above. Total emissions from these source categories in 2011 and 2012 were 11 MMT CO2e.

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