Gary - Keeping in consideration the other responses, printing process and other related activities in the plant impact the amount of NOx and particulates from a plant. In terms of NOx gravure and large flexo operations many have NOx (and SOx) permitting and reporting requirements due to their gas fired drying systems. In terms of particulates - the majority are from cutting/trimming operations as well as cyclone/baler systems. In my experience, aside from reducing the volume of trim scrap from an operation there is little opportunity to reduce the amount of particulates from a plant. However they can, and are, controlled. Most scrap handling systems are equipped with a dust collection system (typically a bag house) which is 98% efficient in capture if properly maintained. Many plants opt for total enclosure of the scrap handling system as well so that particulates are further controlled within the plant. So to reply to inquiry about case studies and other information, I do not recall seeing any materials on these topics. I suspect that is because they have not been raised as a significant opportunity for change. Deb Jacobson
