EHS > CTP

Coal Tar Pitch

CTP-containing products are key raw materials for the smelting industry (Soderberg electrodes).

CTP, which had undergone a risk assessment, was  registered in 2010 by the REACH For Coal Chemical Consortium (R4CC).

The smelting Industry represents either the downstream users of high-temperature Coal Tar Pitch (htCTP) and/or the downstream users of articles (e.g. Søderberg electrodes/cylinders baking in situ) and preparations/mixtures like briquettes or various pastes (hot and/or cold) used for ramming, repair, grouting and tap hole plugging where htCTP is one of the components in the mixture.

CTP is on the candidate list for authorisation. In June 2010, the Member States agreed NOT to prioritise the CTP in the candidate list for authorisation and to address the related PAHs emissions via other pieces of legislation (Industrial Emissions, Water Directives). However, there is no guarantee that this substance will not be subject to an authorisation process in the future.

Coal Tar Pitch (CTP) contains polycyclic aromatic hydrocarbons (PAHs), which are poorly degradable substances that  can be released into the environment. The Netherlands are therefore requesting the classification of CTP as H400 (Very toxic to aquatic life) and H410 (Very toxic to aquatic life with long-lasting effects) within the framework of the next ATP to CLP Regulation. RAC agrees to this proposal in its published opinion.

EUROALLIAGES is concerned about this over-classification, which could,  if adopted, place an unjustified burden on the smelting industry based on a lack of robust scientific grounds.
