The current Ceramic Manufacturing Industry Best Available Techniques (BAT) Reference document, the so-called Ceramic BREF, was published in 2007 and is going to be reviewed officially in 2017. The BREF has gained more importance as it becomes, with the IED Directive, the legal base for the factory permits in the EU. To be prepared for this 2017 revision, the CU BREF Task Force needs to collect data related to the emissions and abatements systems used in the ceramic production sites.  For this purpose a data collection is taking place. The national associations are involved in this exercise and translated versions of the questionnaires are being circulated to the factories. It is important for companies to take part in this data collection.
