CD Aero Eliminates Use of nPB

  After a change in ownership, CD Aero worked with the Toxics Use Reduction Institute (TURI) and the Massachusetts Office of Technical Assistance (OTA) to find a safer alternative cleaning process to the use of n-propyl bromide (nPB). With a new aqueous cleaning process, the company is now saving $46,000 per year, protecting health and safety and reducing its regulatory obligations. Download PDF file (317.67 kB)

Assabet Auto Tech Program. 2019

  The Assabet Valley Regional Technical High School Automotive Technology (Auto Tech) Program is creating a safer and healthier work environment for students by replacing harsh solvents with a microbe-based (bio-based) technology to clean dirty parts. Download PDF file (262.82 kB)

Morgan Advanced Materials Triumphs over TCE

  Morgan Advanced Materials is a global manufacturer specializing in advanced materials. The New Bedford, MA facility manufactures ceramic feedthroughs for medical and aerospace markets. The facility used trichloroethylene (TCE) for several tasks, including wax removal after ceramic grinding. After investing in a new vapor degreaser system and a new solvent mixture tested by the TURI laboratory, Morgan eliminated the use of TCE, thereby enhancing the health and safety of its workers, eliminating TURA reporting, and reducing costs.

Umicore Electrical Materials Eliminates Use of Perchloroethylene

  Umicore Electrical Materials USA Inc. manufactures contact materials, including clad metals, tapes, buttons, absorber rods, and brazing materials for the electronics industry. The facility had been using a vacuum degreaser with the cleaning solvent perchloroethylene (PCE). EHS staff at the facility wanted to eliminate the use of PCE entirely. Umicore identified and purchased a new vacuum degreaser to be used with a new, modified alcohol-based cleaning solvent blend, Metalnox M6386. Download PDF file (280.57 kB)

Riverdale Mills Innovates to Reduce Chemical Use

  The manufacturing process employed by Riverdale Mills historically required the use of hydrochloric acid, ammonium hydroxide and sodium hydroxide. To reduce the amount of chemicals used, the company designed, fabricated, and installed a two-part dual brush roll system to remove excess water and acid at two points in the galvanizing process. Riverdale immediately realized a significant reduction in toxics use, an improved work environment, and increased cost savings. Download PDF file (956.56 kB)

Free Wheelers Bike Shop. 2019

  The Toxics Use Reduction Institute (TURI) Cleaning Laboratory provides performance testing for safer cleaning products. The lab partnered with the UMass Lowell Free Wheelers bike shop, located on campus, to evaluate its current cleaners. Free Wheelers and the lab were interested in identifying cleaning products and processes that would protect the health and safety of the shop workers and enhance the shop's contribution to the University's sustainability efforts. The lab conducted a comprehensive evaluation of cleaners and degreasers currently used by the shop to remove common contaminants found on bike frames, chains, and wheels. Products were screened for effectiveness and safety; some cleaners were removed from inventory. Download PDF file (812.25 kB)

912 Auto Center - Switching to Water Based Paint and Paint Gun Washers. 2014.

  912 Auto Center made a number of changes to their operations when they moved their location to Dorchester from Mattapan. These changes were spurred by the owner's commitment to improving the quality of both his product and the working environment. The success he has experienced as a result of switching from primarily solvent-based painting and paint gun washing to primarily water-based painting and paint gun washing systems has been significant. Operating costs are reduced, performance and productivity are improved, and worker satisfaction is enhanced. Download PDF file (2.16 MB)

BOC Edwards - Enclosed Automated Wash System. OTA 2001.

  To improve quality of service and environmental, health and safety performance, BOC Edwards installed an enclosed, automated wash system and closed-loop wastewater treatment unit at its pump-remanufacturing center in Wilmington, MA. The new system recycles nearly 100% of the process water used to clean pump components and decreases waste sludge by approximately 80% compared to previous operations. Download PDF file (118.17 kB)

Inner-Tite Corporation - Closed Circuit Degreaser and Other Changes Improve Environmental Health and Safety. OTA 2001.

  Inner-Tite Corporation replaced its existing parts degreasing equipment with two entirely enclosed Forenta degreasing units. The new degreasing equipment has reduced air emissions of trichloroethylene (TCE) by 97% and will save the company over $12,000 annually in avoided chemical purchases. Download PDF file (148.58 kB)

Cleaning Urethane, Ink and Paint Manufacturing Vessels - Alternatives to Toxic Solvents in Cleaning Systems. 1997.

  In 1995, Raffi and Swanson, Inc. received a $20,000 grant from the Massachusetts Toxics Use Reduction Institute (TURI) to examine alternatives to toxic solvents in the company’s cleaning operations. Raffi and Swanson set a project goal of reducing chemical use and byproducts from these cleaning operations by 50%. Raffi and Swanson met this goal, reducing chemical use and emissions by roughly 50% (roughly 46,000 lb.) and chemical byproducts 50% (roughly 200,000 lb.). These reductions were achieved through the implementation of over thirty worker-identified changes to cleaning practices. These changes included redesigning equipment and procedures to eliminate the need for solvent cleaning, methods to increase solvent reuse, and more careful management of solvent distribution and application throughout the site. These changes have saved Raffi and Swanson approximately $18,000/yr. During the course of the project, Raffi and Swanson worked closely with the TURI Surface Cleaning Lab to evaluate alternatives to N-methyl pyrrolidone in the company’s urethane reactor vessel cleaning operation. The Surface Cleaning Lab evaluated seven aqueous cleaners and four semi-aqueous cleaners as replacements for N-methyl pyrrolidone. Two semi-aqueous cleaners were the most promising substitutes but the inability to recycle the cleaners makes them cost-prohibitive. Download PDF file (1.34 MB)
