Air pollution is a hot topic globally and shows no signs of abating. According to EURACTIV, some 40 million people in the 115 largest cities of the EU are exposed to pollution exceeding World Health Organization (WHO) air quality guideline values (for at least one pollutant). The result is approximately 100,000 premature adult deaths each year.
Of course, one of the biggest contributors to air pollutants are gas streams from industrial processes containing volatile organic compounds (VOCs) and hazardous air pollutants (HAPs). Gas streams are produced by processes requiring ventilation and are commonly seen in paint booths, printing and paper mills.
