Industrial Cleaning

Bio Based Floor Stripping

The purpose of this project was to evaluate bio-based replacements at a VA Hospital against products currently in used at that facility. The first phase evaluated a heavy duty floor finish stripper. The second phase evaluated hard surface cleaning products. Both phases were based on the preliminary laboratory testing previously at the facility. Read more...

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)

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)

Smith & Wesson - 1,1,1-Trichloroethane Elimination. OTA 1995.

  Smith and Wesson implemented process changes to reduce the use of l,1,1-Trichloroethane (TCA) in its cold degreasing operations. The installation of agitating parts washers and drum top washers which use an aqueous solution has eliminated the use of TCA and saves the firm at least $6,870 annually. Download PDF file (21.35 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)
