The last meeting of the Technical Working Group that discusses the next BREF (Best Available Techniques (BAT) Reference Document ) on Waste Treatment (WT) will take place in the facilities of the IPTS from the 19th to the 23rd of March.
In the first draft the word "odour" appeared 251 times. This is a measure of the importance of the odour management in this BREF. After a few drafts and plenty of discussion it looks like this very important document will come up with a new text.
There are over 30 BREF documents published but the important thing about this new and revised text is that it will come with the new Emission Levels Associated with BATs (BAT-AELs) which are compulsory Emission limits for any installation pursuing an Environmental Integrated authorization. The key here is that in the previous BREF these limits were set as references but they were not obligatory for any facility.
The last IRPP BREF approved for large poultry and pig farms set limits only for ammonia and not for odours, which is not quite the same. We hope this BREF goes one step forward and starts to regulate the real odour impact (not the SH2 impact). It seems that there is a general fear to set limits in terms of odour units or meters of setback distance, in Europe at this stage. Once this BREF is ready and approved, any WT facility in Europe will have compulsory BATAELs... maybe also for odour emissions preventing future problems with the neighbours.
