Emission problem for paint booths
In 2010, international agreements were made on the reduction of harmful emissions per country. The National Emission Ceiling Directive (NEC) prescribes that countries may emit less NOx, SO2, NH3 and VOCs (Volatile Organic Compounds), now and in the future.
Currently, especially NOx and NH3 are very topical due to the current nitrogen crisis. There, compliance with the emissions ceiling has even been enforced by the courts. The VOC Ceiling seems to be less well known, but is certainly just as relevant for paint booths.
For example, these are the figures for the VOC Emissions Ceiling for the Netherlands:
2010-2019: 185,000,000 kg / year = 237,000,000 liters of solvent
2020-2029: 167,000,000 kg / year = 214,000,000 liters of solvent
From 2020, less VOCs may be emitted in total. But with the current way of working, that is an impossible task for paint booths. Until now, a good solution was not available.
