Abstract |
The report gives results of a study to evaluate several pollution prevention techniques that could be used to reduce styrene emissions from open molding processes in the fiberglass-reinforced plastics/composites (FRP/C) and fiberglass boat building industries. Styrene emissions using standard industry techniques, materials and equipment were evaluated in a controlled environment and compared to a baseline condition to determine the effects of these pollution prevention techniques on styrene emission. The study found that using controlled spraying (i.e., reducing overspray), low-styrene and styrene suppressed materials, and nonatomizing application equipment can reduce styrene emissions by from 11 to 52%. The calculated emission factors were from 1.6 to 2.5 times the mid-range AP-42 emission factors for the corresponding gel coat and resin application. These results indicate that facilities using AP-42 emission factors to estimate emissions in open molding processes are likely to underestimate actual emissions. |
