+ | In Germany, soda ash is produced in three production facilities, all of which use the Solvay process. The production data is thus confidential. | ||
- | In former years, facilities with higher ammonia emissions existed in the New German Länder. However, after 1992, emissions of NH,,3,, occur at a lower level. | ||
