United Kingdom
| 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. | |
