Wastewater treatment and discharge

Emissions from Danish wastewater treatment plants from anaerobic sludge treatment.

This sector report present a verification of the country-specific methane emissions factor of 1.3 % of the reported methane recovery in terms of biogas production at Danish wastewater treatment plants from anaerobic sludge treatment.

The verification is based on a combination of national level COD balance, as recommended by the UNFCCC review team, supplemented by plant level reported data. Secondary, the correctness of the percentage of the Danish population not connected to the collective sewer system is documented. Lastly a first approach for including direct N2O emissions from separate industries is presented.
