This BREF addresses installations for the tanning of hides and skins with a treatment capacity exceeding 12 tonnes of finished products per day. The activity is included under point 6.3 of Annex I to the Industrial Emissions Directive 2010/75/EU (IED). The types of hides and skins are restricted to those of ovine and bovine origin because the production capacities for any other type of raw material for the production of leather and furs are far below the threshold value given in the Directive.
