# Commission Implementing Decision (EU) 2019/2031 of 12 November 2019 establishing best available techniques (BAT) conclusions for the food, drink and milk industries, under Directive 2010/75/EU of the European Parliament and of the Council (notified under document C(2019) 7989) (Text with EEA relevance), Division 6.2: Emissions to air

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

BAT 26. In order to reduce channelled emissions of organic compounds to air from fish smoking, BAT is to use one or a combination of the techniques given below.
Technique
Description
(a)
Biofilter
The waste gas stream is passed through a bed of organic material (such as peat, heather, root, tree bark, compost, softwood and different kinds of combinations) or some inert material (such as clay, activated carbon, and polyurethane), where organic (and some inorganic) components are transformed by naturally occurring microorganisms into carbon dioxide, water, other metabolites and biomass.
(b)
Thermal oxidation
See Section 14.2.
(c)
Non-thermal plasma treatment
(d)
Wet scrubber
See Section 14.2.
An electrostatic precipitator is commonly used as a pre-treatment step.
(e)
Use of purified smoke
Smoke generated from purified primary smoke condensates is used to smoke the product in a smoke chamber.
Table 11
BAT-associated emission level (BAT-AEL) for channelled TVOC emissions to air from a smoke chamber
The lower end of the range is typically achieved when using thermal oxidation.
The BAT-AEL does not apply when the TVOC emission load is below 500 g/h.
Parameter
Unit
BAT-AEL (average over the sampling period)
TVOC
mg/Nm3
15–50
The associated monitoring is given in BAT 5.
