Volatile Emissions
FRP industries benefit by reducing
volatile emissions. These benefits include:
- Fewer emissions implies better
raw materials use, improving the bottom line.
- Less concern about Occupational
Safety and Health Administration (OSHA) regulations
related to worker exposure to chemicals, especially
styrene.
- Less concern about regulation of
air pollutants as a result of the 1990 Clean Air Act
Amendments (CAAA), especially the recently proposed
Maximum Achievable Control Technology (MACT) standards.
- Reduced disposal cost of spent
solvents as hazardous waste.
- Reduced risk of fires caused by
high concentrations of chemicals in the workplace.
Most FRP processors
are major sources of volatile emissions. The emissions
from FRP processing facilities include styrene, the
volatile component of polyester resin and gelcoat; and
acetone, a solvent used to clean tools and other surfaces
contaminated with resin.
Emissions
Estimating The American Composites Manufacturers
Association (ACMA) Styrene Emissions Test Project produced
a comprehensive body of information on emissions from
open molding, including technical support guides and
information on emissions factors.
Reducing
Volatile Emissions in the Fiber Reinforced Plastics
Industry Most FRP processing facilities are
major sources of volatile emissions. Their emissions
include styrene, the volatile component of polyester
resin and gelcoat; and acetone, a solvent used to clean
tools and other surfaces contaminated with resin. This
fact sheet discusses opportunities for reducing these
emissions.
Spray Gun Pressure and Emissions
Higher spray pressure leads to higher styrene emissions
through greater atomization and increased overspray.
Proper spray gun selection and calibration reduce emissions.
