The European Commission Implementing Decision establishing the best available techniques (BAT) conclusion for the slaughterhouses, animal by-products and/or edible co-products industries has been made public. The BREF document was under review, and the latest draft was published in March 2023. The final text of the BREF has not been published to date.
On December 18, 2023, the Official Journal of the European Union published the Commission Implementing Decision of December 11, 2023, establishing conclusions on the Best Available Techniques (BAT) under Directive 2010/75/EU of the European Parliament and of the Council on industrial emissions, for slaughterhouses, animal by-products and/or edible co-products industries. This directive is very interesting because it brings the second panaeuropean odour limit after the one published in 2018 for Waste Treatment. These are some key points on this new regulation, regarding odours.
The conclusions are binding for the affected activities, and they are published in the form of the European Commission Implementing Decision. As mentioned, this would be the second sector-specific BREF to establish odour emission limits after the BREF for waste treatment.
This BREF brings several innovations regarding odours, with one of the most significant being the imposition of emission levels associated with BAT (BAT-AEL) for channelled emissions to air of odour from rendering, fat melting, blood and/or feather processing. This also applies to for channelled emissions to air of odour from fishmeal and fish oil production. Although both BAT-AELs include some exceptions in their application, the emission levels in this BREF are quite restrictive. However, they do not take into account the location of the activities concerning potential receptors of odour annoyance.

Additionally, as has been customary since 2016 in all updated BREFs belonging to any Potentially Odour-Generating Activities, the Odour Management Plan (OMP) has been included as one of the BATs (BAT 18). However, it is clearly stated that "The applicability is restricted to cases where an odour nuisance at sensitive receptors is expected and/or has been substantiated".
In the conclusions of the 2006 BREF, the mention of odours goes no further than good practices and proposals for using odour control systems, such as "to duct air from the installation and the pre-combustion equipment to combustion chambers, operate odour arrestment techniques, when the incinerator is not working, when odour prevention is not reasonably practicable and use a carbon filter for odour abatement, when incinerators are not operating."
