This percentage was determined by comparing the average amount of materials used and wastes produced at the old shop with the amount of materials used and wastes produced during the first months of operation at the new shop. Waste Reduction Measures To accomplish its waste reduction goals, Humes Collision Center installed specialized equipment and implemented operating procedures that reduced waste. In addition, these refrigerants are for sale only to licensed operators. Antifreeze Recycling Humes uses a mobile recycling service provided by Coolant Recovery Company of Minneapolis, Minnesota. By recycling the used antifreeze, Humes purchases smaller amount of new antifreeze, thereby reducing costs.
Recycling used antifreeze also eliminates generating antifreeze wastes.
The sanding system consists of a vacuum pump connected to a hose at each work station, and a sanding head attached to each hose. During the sanding process, the dust is pumped out and collected in a sealed container outside the shop. The sanding dust was tested as nonhazardous, and is disposed of as nonhazardous solid waste. The new contained sanding system prevents sanding dust from being emitted into the shop, and has greatly reduced employee labor costs for cleaning dust off cars and in the shop. The need to redo work on cars for damage from dust particles has almost been eliminated.
