Method

Activity data

The yearly production figures were taken from the annual statistical report of the German association for non-ferrous metals [Lit. 1].

Emission factors

The emission factors are either default values according to the 2019 EMEP/EEA air pollutant emission inventory guidebook [Lit. 2] or determined in several research projects or from companies environmental reports [Lit. 3].

Pollutant EF Unit Source
HCB 1 mg/t Emission guidebook 2019 [Lit. 2]
PCDD/F 2.9 µg/t Emission guidebook 2019 [Lit. 2]

As 2 g/t Emission guidebook 2019 [Lit. 2]
Cd 486.428 mg/t NE-G-K [Lit. 3]
Cu 46,088.62 mg/t NE-G-K [Lit. 3]
Hg 2.644 mg/t NE-G-K [Lit. 3]
Pb 21,977.15 mg/t NE-G-K [Lit. 3]

Recalculations

Due to the use of new data for emission factors [Lit. 4], recalculations have been carried out for the entire time series for TSP, SO2, As, Cu and Pb in Primary copper production. The new EF for TSP, As, Cu and Pb are based on actual plant specific data. They are significantly lower than the default values from the EMEP/EEA Guidebook. Only the EF for SO2 is slightly higher than the previously used default value.

For pollutant-specific information on recalculated emission estimates for Base Year and 2018, please see the pollutant specific recalculation tables following chapter 8.1 - Recalculations.

Planned improvements

No category specific improvements are planned.
