# 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 2.1.1: Emissions to air

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

BAT 25. In order to reduce emissions to air of dust, and of particulate-bound metals, PCDD/F and dioxin-like PCBs, BAT is to apply BAT 14d and to use one or a combination of the techniques given below.
Technique
Description
Applicability
a.
Cyclone
See Section 6.1.
Cyclones are mainly used as preliminary separators for coarse dust.
Generally applicable.
b.
Fabric filter
See Section 6.1.
May not be applicable to exhaust air ducts directly connected to the shredder when the effects of deflagration on the fabric filter cannot be mitigated (e.g. by using pressure relief valves).
c.
Wet scrubbing
See Section 6.1.
Generally applicable.
d.
Water injection into the shredder
The waste to be shredded is damped by injecting water into the shredder. The amount of water injected is regulated in relation to the amount of waste being shredded (which may be monitored via the energy consumed by the shredder motor).
The waste gas that contains residual dust is directed to cyclone(s) and/or a wet scrubber.
Only applicable within the constraints associated with local conditions (e.g. low temperature, drought).
Table 6.3
BAT-associated emission level (BAT-AEL) for channelled dust emissions to air from the mechanical treatment of waste
When a fabric filter is not applicable, the upper end of the range is 10 mg/Nm3.
