WRATT II Solvents - The Good, the Bad & the Banned Chapter 03: Case Study - TRW Ross Gear Division
Chapter Abstract: This is clip 3 of 6 for this video. TRW Ross Gear Division is a manufacturer of hydraulic motors, hydrostatic steering units and manual steering gears. They are recipients of the Governor's Award for Excellence in Hazardous Waste Management in recognition of their efforts to eliminate the use of trichloroethylene. They started by analyzing the soils on their product.. They ended up with an alkaline cleaning solution. A unique process had to be developed to meet their specific needs. The aqueous cleaning system has greatly improved the part cleanliness. The reduction of source soils has also helped their overall ability to clean. There are three types of washers used, a 3-stage immersion washer, a 2-stage spray washer and a single stage turbo washer. The new system has eliminated the health risks to employees, their hazardous waste has been reduced by 50% and disposal costs have been reduced.
