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
Fiberglass boat builder implements on-site reclamation and reduces virgin acetone purchases.
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.
