In Germany, soda ash is produced in three production facilities, all of which use the Solvay process.
Methodology
Activity data
The Federal Statistical Office determines the total amounts of soda ash produced in Germany, but only regarding confidentiality.
Emission factor
Emission factors (for TSP and NH3) are confidential regarding activity data restrictions.
Discussion of emission Trends
The steep reduction especially for NH3 at the beginning of the 1990s was due to closures in the eastern German industrial sector. For year 1990 for eastern Germany is in case of TSP pointed out the summary figure for the Chemical Industry as a whole. However, after 1992, emissions of NH3 occur at a lower level.
All trends in emissions correspond to trends of emission factors. No rising trends are to identify.
Recalculations
With EF and AD remaining unrevised, recalculations were not necessary.
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
At the moment, no category-specific improvements are planned.
