# Commission Implementing Decision (EU) 2020/2009 of 22 June 2020 establishing the best available techniques (BAT) conclusions, under Directive 2010/75/EU of the European Parliament and of the Council on industrial emissions, for surface treatment using organic solvents including preservation of wood and wood products with chemicals (notified under document C(2020) 4050) (Text with EEA relevance), Division BAT 28: In order to reduce total VOC emissions, BAT is to use a combination of the techniques given below.

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

Technique
Description
Applicability
Material-based and printing techniques
(a)
Use of low-IPA or IPA-free additives in dampening solutions
Reduction or avoidance of isopropanol (IPA) as a wetting agent in dampening solutions, through substitution by mixtures of other organic compounds which are not volatile or have a low volatility.
Applicability may be limited by technical and product quality requirements or specifications.
(b)
Waterless offset
Modification of the press and the pre-press processes to enable the use of specially coated offset plates, eliminating the need for dampening.
May not be applicable for long print runs due to the need for more frequent changes of plates.
Cleaning techniques
(c)
Use of VOC-free solvents or solvents with low volatility for automatic blanket cleaning
Use of organic compounds which are not volatile or have a low volatility as cleaning agents for automatic blanket cleaning.
Generally applicable.
Off-gas treatment techniques
(d)
Web offset dryer integrated with off-gas treatment
A web offset dryer with an integrated off-gas treatment unit, enabling incoming dryer air to be mixed with a part of the waste gases returned from the off-gas thermal treatment system.
Applicable to new plants or major plant upgrades.
(e)
Extraction and treatment of air from the press room or the press encapsulation
Routing of extracted air from the press room or the press encapsulation to the dryer. As a result, a part of the solvents evaporated in the press room or press encapsulation is abated by the thermal treatment (see BAT 15) downstream of the dryer.
Generally applicable.
