Revised BAT conclusions for waste treatment published
Following a long revision process (more info here), 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.
The document contains 53 individual BAT conclusions. Of these, 24 apply to the sector as a whole and 29 apply to the most common waste treatments, including mechanical, biological and physico-chemical treatments and treatment of water-based liquid waste. They also apply to temporary waste storage and independent waste water treatment plants whose main share of treated effluent originates in waste treatment installations.
We have prepared a summary for members of the BAT conclusions that relate to composting and AD sites, please see here.
BAT-associated emission levels
The BAT conclusions include BAT-associated emission levels (BAT-AELs) which have the potential, through their translation into emission limits, to drive a sizeable reduction in emissions from the waste treatment sector.
In addition to covering the emission levels and other environmental performance aspects of several (production) techniques, they include standards for how the technology is used and the way in which the installation is designed, built, maintained, operated and decommissioned.
