V.H. Blackinton & Co. - Halogen Solvent Elimination, Chemical Reduction and Zero Discharge. OTA 2003.

  In the early 1990's V.H. Blackinton began a continuous improvement program to reduce chemical use and eliminate certain hazardous chemicals. By engaging company employees and working with vendors, along with the help of the Office of Technical Assistance (OTA), V.H. Blackinton eliminated the use of ozone depleting Freon, trichloroethylene (TCE), ammonia, and volatile organic compounds (VOC). The company made substantial investments to modernize their plating and finishing operations, leading to significant reductions in water use and in the use of acids and bases in waste treatment and plating operations. As a result, V.H. Blackinton is no longer required to report under the Toxic Use Reduction Act (TURA) and have closed the loop on their wastewater discharge. Download PDF file (25.88 kB)

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. The new formulation helps Hampden Papers reduce annual VOC emissions by 4-6 tons. More significantly, the change eliminates the use of ethylene glycol monobutyl ether and thereby frees the company from filing requirements under both the Massachusetts Toxics Use Reduction Act (TURA) and Superfund Amendments and Reauthorization Act (SARA) Section 313.
