Most FRP processors are major sources of volatile emissions.
Because of these contaminants, used sorbents may be hazardous and require special handling. Inappropriate handling may impact employee health and safety. Source reduction falls under the pollution prevention umbrella, and includes any practice that reduces the amount of any hazardous substance or pollutant prior to recycling or treatment. The CFA Styrene Emissions Test Project has produced the most comprehensive body of information on emissions from open molding. During the course of the project, the project identified four types of variables, which effect the measurement process, or the determination of emissions.
