Coal Combustion Products and REACH

On 1st June 2007 the REACH-Regulation (Registration, Authorisation, Evaluation and Restriction of Chemicals) entered into force. Each producer of coal combustion products (CCPs) placed on the market as construction materials have to register the substances. In Europe, non registered substances can not be placed on the market after 1st June 2008 any more! For CCPs, since they are already registered in the European Inventory of the Existing Commercial Chemical Substances (EINECS) the deadline for registration is extended to 30 November 2010. This is only true if the producer pre-register in the period of June 1 to November 30, 2008! The registration requires i.a. comprehensive information about toxicology and ecotoxicology of the substances.
A project group is dealing with the details for the pre-registration of coal combustion products. Members of the project group are i.a. representatives of the associations BDEW, VGB, BVK, BV Gips, EuroGypsum and ECOBA. The work of the project group is aiming at the formation of European consortia for the common registration of calciumsulfate und ashes from power plants.
European producers of coal combustion products are invited to join the consortia for CCPs.
