This study developed emission factors for volatile organic compounds (VOCs) and particulate matter during polycarbonate (PC) and PC/ABS blend processing. These factors help estimate industrial emissions from polymer extrusion operations.

Area of Science:

  • Polymer Processing
  • Environmental Science
  • Chemical Engineering

Background:

  • Polycarbonate (PC) and PC/ABS blends are widely used polymers.
  • Industrial processing of these polymers can release volatile organic compounds (VOCs) and particulate matter.
  • Accurate emission factors are needed for environmental impact assessments and regulatory compliance.

Purpose of the Study:

  • To quantify emission factors for selected volatile organic compounds (VOCs) and particulate emissions.
  • To provide data for estimating atmospheric releases during commercial polycarbonate processing.
  • To support environmental management in the polymer processing industry.

Main Methods:

  • Processing eight commercial grades of polycarbonate (PC) and one PC/ABS blend using a small commercial-type extruder.

  • Maintaining a constant extrusion temperature of 304 degrees C.
  • Calculating emission factors as pounds released per million pounds of polymer resin processed (ppm (wt/wt)).

    • Main Results:

    • Emission factors were determined for specific volatile organic compounds (VOCs) and particulate emissions.
    • Data were collected for various PC and PC/ABS formulations.
    • Calculated emission factors are reported in ppm (wt/wt).

    Conclusions:

    • The developed emission factors are applicable to similar PC processing operations.
    • Processors can use these factors to estimate emission quantities from their operations.
    • This research contributes to better environmental stewardship in polymer manufacturing.
