The most significant pollutant from the asphalt plants is particulates. The emission, factors (without controls) are 18 kg/0.91 metric ton (40 lb/short ton) for the hot-mix plants and 4 kg/0.91 (2 metric ton (8 Ib/short ton) for the roofing segment. These quantities represent about 0.65 percent of the national total of particulate emissions.
