Method

Activity data

The yearly production figures were taken from the annual statistical report of the German association for non-ferrous metals [Lit. 1]. In 2022 the primary and secondary zinc production amounted to 134.9 kt.

Emission factors

The emission factor for SOx is a tier 1 default value according to the EMEP/EEA air pollutant emission inventory guidebook 2023 [Lit. 2] and is supposed to be constant. All other emission factors are tier 2 level factors, have a decreasing trend and were determined in research projects. The EF for the heavy metals (HM) are taken from a research project [Lit. 3].

Table 1: emission factors applied for primary and secondary zinc production (4 digits rounded off)

EF (primary) EF (secondary) Unit
SO2 1350 g/t
PM2.5 38.5 g/t
PM10 61.3 g/t
TSP 100 g/t
As 123.9 30 mg/t
Cd 1085 230 mg/t
Hg 500 1.5 mg/t
Pb 19.605 950 mg/t
Zn 51.968 9 g/t
PCB 1 mg/t
PCDD/F 0.15 µg/t

Recalculations

With activity data and emission factors remaining unrevised, no recalculations were carried out compared to Submission 2022.

Planned improvements

No category specific improvements are planned.
