The data incorporates CO2 emissions associated with treating and transporting of waste as well as the emissions which are potentially mitigated where future resource and energy consumption is reduced (e.g. recycling). Depending on the disposal method selected, therefore, the disposal of some waste types results in a negative value for CO2 emissions within CarbonKit - these values represent CO2 emissions saved. All data represents the aggregate global warming effect of six greenhouse gases (CO2, CH4, N2O, PFC's, HFC's, CFC's) expressed as CO2 equivalents (CO2e).
To use this category select the type of waste using drill downs, then enter the quantity of waste and a disposal method. If no disposal method is entered CarbonKit will return a value associated with landfill disposal.
Disposal methods should be selected and entered as follows:
- landfill: this calculates the CO2e emissions associated with the disposal of waste in landfill sites.
- recycling: this calculates the net CO2e emitted in the recycling of waste material (including potential emissions savings where future production is mitigated).
- thermal: this calculates the CO2e emitted in the combustion of waste products.
- embodied: these data represent the total CO2e emissions which are embodied within specific waste materials. These values therefore reflect the unit CO2 emissions of future production for a given material and can be considered to represent the CO2 emissions which are saved by choosing not to dispose of a particular waste product.
