# 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 6: In order to reduce raw material consumption and VOC emissions, BAT is to use one or a combination of the techniques given below.

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

Technique
Description
Applicability
(a)
Centralised supply of VOC-containing materials (e.g. inks, coatings, adhesives, cleaning agents)
Supply of VOC-containing materials (e.g. inks, coatings, adhesives, cleaning agents) to the application area by direct piping with ring lines, including system cleaning such as pig cleaning or air flushing.
May not be applicable in the case of frequent changes of inks/paints/coatings/adhesives or solvents.
(b)
Advanced mixing systems
Computer-controlled mixing equipment to achieve the desired paint/coating/ink/adhesive.
Generally applicable.
(c)
Supply of VOC-containing materials (e.g. inks, coatings, adhesives, cleaning agents) at the point of application using a closed system
In the case of frequent changes of inks/paints/coatings/adhesives and solvents or for small-scale usage, supply of inks/paints/coatings/adhesives and solvents from small transport containers placed near the application area using a closed system.
(d)
Automation of colour change
Automated colour changing and ink/paint/coating line purging with solvent capture.
(e)
Colour grouping
Modification of the sequence of products to achieve large sequences with the same colour.
(f)
Soft purge in spraying
Refilling the spray gun with new paint without intermediate rinsing.
