CO2 which derives from recently sequestered carbon sources and fossil sources are differentiated, since their net impact on atmospheric CO2 concentrations in distinct.
How to use this category
Selecting an emissions scenario
To use this category, select the waste type using the type drill choice.
Next, specify the burning method (continuous incineration, open burning, etc.) and technology (stoker, fluidised bed) using the method and technology drill choices. No technology choice is required for the 'open burning' combustion method.
Specifying activity data
Finally, set the quantity of waste burned using the mass profile item value. CarbonKit assumes that the weight specified is the dry weight of the waste burned. Users can alternatively use the wet weight by setting the isWetWeight profile item value to 'true', in which case CarbonKit will convert wet weight into dry weight using typical dry weight fraction data for each waste type.
Results and calculation
The values returned represent CO2 emissions associated with the waste quantity specified. The following discrete values are returned:
- fossilCO2: CO2 emissions which derived from fossil carbon
- biogenicCO2: CO2 emissions which derived from recently sequestered, biogenic carbon
- totalCO2: fossil and biogenic carbon
- CH4: CH4 emissions associated with the waste quantity specified
- N2O: N2O emissions associated with the waste quantity specified
- CO2e: fossil CO2, CH4 and N2O combined and expressed in terms of CO2e
Note: This category does not cover emissions associated with the burning of glass or metal wastes which are considered by the IPCC to be only rarely burned.
