Pollution Prevention Case Studies The Department of Environmental Management's Office of Customer and Technical Assistance (OCTA) provides assistance to businesses that are seeking to comply with environmental regulations and/or reduce wastes. In helping companies reach these goals, DEM and industry partners have reduced wastes, recycled materials, minimized pollution and, in many instances, increased company profits. The following is a list of 55 specific cases in which DEM was able to assist businesses reach their goals. No endorsements are implied nor should any be inferred for any products or companies identified within these success stories. The OCTA advises that prior to implementing environmental changes, the company consult with proper federal, state, and local regulatory agencies. Industry Type Waste/Material Project Description Boat Builder Acetone Fiberglass boat builder implements on-site reclamation and reduces virgin acetone purchases. Boat Builder VOCs Fiberglass boat builder incorporates infusion molding or the Seeman® Composite Infusion Molding Process (SCRIMP) on a 30 foot sailboat hull and cuts laminating resin usage and volatile organic compound (VOC) production. Boat Builder Acetone Fiberglass boat builder implements on-site solvent reclamation and doubles production without increasing acetone usage. Boat Builder Acetone Fiberglass boat builder switches solvents from acetone to Shipshape® Resin Cleaner and Thermaclean® Gun Flush and implements solvent reclamation. Boat Builder VOCs Fiberglass boat-builder uses a pressure fed roller instead of an air atomized spray gun for laminating applications and reduces volatile compound (VOC) emissions while increasing consistency of parts produced.
