This chapter focuses on techniques that may be employed by fabricare operations to prevent pollution, reduce chemical consumption, and minimize waste, with significant emphasis on perchloroethylene (PCE) and hydrocarbon (HC) solvent technologies. Section 9.1 examines the pollution prevention options with the potential to achieve environmental improvements for facilities using PCE and HC solvent technologies. The most common operating and maintenance procedures, control devices, and their effects are presented, including options for recycling. Methods for extracting solvents are addressed, as are methods for treating spent solvents so that they may be reused. In addition, this section discusses the impact of facility conditions and remedial actions on PCE concentrations in co-located residences (i.e., residences located in the same building as a fabricare operation). Section 9.2 suggests practices and improvements that may help cleaners using machine wetcleaning reduce chemical releases and exposure. Section 9.3 provides a summary of the several major clothes cleaning trade and research associations, their contact numbers, and some of their initiatives and publications involving environmental improvement practices.
