Development of Emission Factors for Polyethylene
2018-11-14 The emissions were measured over a 30-minute period and were related to the weight of resin extruded. The emis-sion factor for each substance measured was reported as pounds evolved to the atmosphere per million pounds of polymer processed (ppm[wt/wt]). Processors using similar equipment can use these emission factors as relative refer-

Development of Emission Factors for Polypropylene
2018-6-7 An emission factor was calculated for each substance measured and reported as pounds released to the atmo-sphere per million pounds of polymer processed [ppm (wt/wt)]. Based on production volumes, these emission factors can be used by processors to estimate emission IMPLICATIONS This study provides quantitative emissions data that were

Emission Factors for Abrasive Materials
2015-9-10 Emission factors are often used to estimate emissions from such industrial operations. Since the development of the emission factors for uncontrolled abrasive blasting operations, prepared for US EPA in 1995, several attempts were made to derive emission factors for particulates.
