Current situation
Metallic mercury in products and applications
Total consumption 320 - 530 t/a Most important
for the use of mercury Chlor- Industry
Dental amalgams Chemicals
COWI A/S Final report 2008

Regulation EC (No) 1102/2008
Purpose ? Phase out mercury exports by 2011 ?
Reduce demand and supply of mercury ? Reduction
of mercury levels in the environment ? Reduction
of mercury emissions Article 2. Metallic
mercury ? No longer used in the Chlor-alkali
industry ? Gained from cleaning of natural
gas ? Gained from non-ferrous mining /smelting
operations ? Extracted from cinnabar ore
From 15 March 2011 Considered as waste and has
to be disposed of
