# Commission Implementing Decision (EU) 2015/2119 of 20 November 2015 establishing best available techniques (BAT) conclusions, under Directive 2010/75/EU of the European Parliament and of the Council, for the production of wood-based panels (notified under document C(2015) 8062) (Text with EEA relevance), Division BAT 21: In order to reduce emissions of volatile organic compounds to air from the drying ovens for the impregnation of paper, BAT is to use one or a combination of the techniques given below.

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

Description of the technique is given in Section 1.4.1.
Technique
Applicability
a
Select and use resins with a low formaldehyde content
Generally applicable
b
Controlled operation of ovens with balanced temperature and speed
c
Thermal oxidation of waste gas in a regenerative thermal oxidiser or a catalytic thermal oxidiser
d
Post-combustion or incineration of waste gas in a combustion plant
Applicability may be restricted for existing installations where a suitable combustion plant is not available on site
e
Wet scrubbing of waste gas followed by treatment in a biofilter
Generally applicable
