# Commission Implementing Decision (EU) 2018/1147 of 10 August 2018 establishing best available techniques (BAT) conclusions for waste treatment, under Directive 2010/75/EU of the European Parliament and of the Council (notified under document C(2018) 5070) (Text with EEA relevance), Division 4.8.1: Overall environmental performance

Extent: E+W+S+N.I.

BAT 51. In order to improve the overall environmental performance and to reduce channelled emissions of PCBs and organic compounds to air, BAT is to use all of the techniques given below.
Technique
Description
a.
Coating of the storage and treatment areas
This includes techniques such as:
resin coating applied to the concrete floor of the whole storage and treatment area.
b.
Implementation of staff access rules to prevent dispersion of contamination
This includes techniques such as:
access points to storage and treatment areas are locked;
special qualification is required to access the area where the contaminated equipment is stored and handled;
separate ‘clean’ and ‘dirty’ cloakrooms to put on/remove individual protective outfit.
c.
Optimised equipment cleaning and drainage
This includes techniques such as:
external surfaces of the contaminated equipment are cleaned with anionic detergent;
emptying of the equipment with a pump or under vacuum instead of gravity emptying;
procedures are defined and used for filling, emptying and (dis)connecting the vacuum vessel;
a long period of drainage (at least 12 hours) is ensured to avoid any dripping of contaminated liquid during further treatment operations, after the separation of the core from the casing of an electrical transformer.
d.
Control and monitoring of emissions to air
This includes techniques such as:
the air of the decontamination area is collected and treated with activated carbon filters;
the exhaust of the vacuum pump mentioned in technique c. above is connected to an end-of-pipe abatement system (e.g. a high-temperature incinerator, thermal oxidation or adsorption on activated carbon);
the channelled emissions are monitored (see BAT 8);
the potential atmospheric deposition of PCBs is monitored (e.g. through physico-chemical measurements or biomonitoring).
e.
Disposal of waste treatment residues
This includes techniques such as:
porous, contaminated parts of the electrical transformer (wood and paper) are sent to high-temperature incineration;
PCBs in the oils are destroyed (e.g. dechlorination, hydrogenation, solvated electron processes, high-temperature incineration).
f.
Recovery of solvent when solvent washing is used
Organic solvent is collected and distilled to be reused in the process.
The associated monitoring is given in BAT 8.
