Information on the waste category should include information of the origin of the waste (MSW, Industrial, Sludge or Other) and type of waste (Food waste
1or Garden and Park Waste).
2 If anaerobic digestion involves recovery and energy use of the gas, the emissions should be reported in the Energy Sector.
3 Information on whether the amount treated is given as wet or dry weight should be given.

4 Users may either enter all MSW incinerated in the MSW row or the amount of waste by composition by adding the appropriate rows.
5 All relevant fractions of fossil C should be included. For consistency with the CH4 and N2O sheets, the total amount incinerated should be reported here. However the fossil CO2 emissions from MSW should bereported either for total MSW or its components.
