emissions from plastics during melting processes.3-8Most of these studies have indicated that the emitted VOCs originated from polymer degradation. However, there might be additional mechanisms responsible for the VOC emissions. For instance, plastic additives such as antioxi- dants and plasticizer are expected to affect the composi-

processes, these emissions are discussed in Sections 6.6, "Plastics", and 6.10, "Synthetic Rubber". Examination of VOC pollutant emissions from the synthetic fibers industry has recently concentrated on those fiber production processes that use an organic solvent to dissolve the polymer for extrusion or that use an organic solvent in some other

Plastic and Resin Industries Emission Control has successfully addressed emissions from a broad variety of plants in the plastic and resin industries including at rigid packaging, flexible packaging, resin production, pultruded products, foam products, thermoplastic roofing, specialty film and sheet, and other plants.

The factors used to estimate the emissions of CO2, CH4 and N2O resulting from the combustion of natural gas (which represents approximately 85 percent of the plastics product sector direct emissions) are shown in Table 3-2. The CH4 and N2O emissions are minor compared to the CO2 emissions.

Emission factors for selected volatile organic and particulate emissions were developed over a range of temperatures during extrusion of polyethylene resins 

Emission factors for selected volatile organic compounds (VOCs) and particulate emissions were developed over a range of temperatures during extrusion of three mixtures of ethylene-vinyl acetate (EVA) copolymers and two mixtures of ethylene-methyl acrylate (EMA) copolymers. A mixture of low-density polyethylene (LDPE) resins was used as a control.
