Revised BAT conclusions for waste treatment published

Following a long revision process, the BAT (best available technique) conclusions from the waste treatment BREF have been published in the Official Journal of the EU. 

You can see the press release here and download the BAT conclusions here. This is an important document for all composting and AD sites that are operating as installations or with PPC permits (i.e. have a capacity of over 75t/day for composting or over 100t/day for AD). 

How soon do sites have to comply?

The BAT conclusions provide national authorities with the technical basis for setting permit conditions for installations. There is a 4 year period for member states to implement the conclusions for existing waste treatment installations (i.e. first permitted before the publication of the BAT conclusions). New installations (i.e. first permitted after the publication of the BAT conclusions) need to comply immediately with the new requirements.


While the main aim of these BAT conclusions is to reduce emissions from different waste treatments, other environmental issues – such as energy efficiency, resource efficiency (water consumption, reuse and recovery of materials), prevention of accidents, noise and odour, management of residues – are also covered.

We have prepared a summary for members of the BAT conclusions that relate to composting and AD sites, please see here

What about Brexit?

The Government have released a paper on what the plans are for Industrial Emission standard in the event of a 'no-deal' Brexit. Full details here but in essence the UK government would make secondary legislation to ensure the existing BAT conclusions continue to have effect in UK law after we leave the EU, to provide powers to adopt future BAT Conclusions in the UK and ensure the devolved administrations maintain powers to determine BAT through their regulatory regimes.

Please contact Jenny if you require any further information.
