Hampden Papers, Inc. - Reduction of VOC Emissions Leads top Savings. OTA 1998.

  In an ongoing effort to limit emissions and reduce use of hazardous chemicals, Hampden Papers spent four years researching, developing, testing and implementing a new coatings formulation used in over 70% of the company's manufacturing capabilities.
