•  INCREASE scrap metal value.Scrap metal increases of 25% to 100%Steel shavings and cast iron are also more valuable in compacted form•  RECOVER machine cutting fluids.Scrap metal carries 20% to 30% of its weight in coolant. Scrap metal, steel and cast iron each carry about 10% coolant• MINIMIZE liability exposure from coolant

laden chips• REDUCE material handling cost.
