|Volatile Organic Compounds (VOCs) and odors are natural by-products of many chemical manufacturing processes. The manufacturing of powdered and liquid flavorings & fragrances involves production phases where VOCs and odors can escape into the ambient air. Recapture of the VOCs is important in the prevention of air pollution and smog. Smog is formed when VOCs react with nitrogen oxides (NOx) in the presence of sunlight. The reaction forms ground level ozone, airborne particulates, and some other pollution.
Ozone has been selected as the standard to measure ground level pollution, a precursor under EPA’s criteria pollutant program. Areas of the country that have ozone readings above EPA guidelines are ruled nonattainment areas and have stricter regulations for VOC, CO, and NOx emissions. This proves that although the compounds that create offensive odors may not be present in sufficient concentrations to present a health risk, they can diminish the quality of life for the community surrounding the manufacturing process.
