COOLANTS INEVITABLY BECOME CONTAMINATED BY METAL CHIPS AND FINES, TRAMP OILS, AND BACTERIA. THESE CONTAMINATED COOLANTS ARE CONSIDERED HAZARDOUS INDUSTRIAL WASTES AND THUS THEIR DISPOSAL IS EXPENSIVE, DIFFICULT, AND STRINGENTLY REGULATED. FACED WITH THESE SKYROCKETING COSTS, METALWORKING COMPANIES TURNED TO PACKAGED RECYCLING UNITS AND SOON FOUND THEMSELVES TAKING ON THE BURDEN OF AN ADDITIONAL BUSINESS--RECYCLING. ON-SITE RECYCLING UNITS REMAINED A FIXTURE IN THE METALWORKING INDUSTRY AND EVENTUALLY EVOLVED INTO A PORTABLE RECYCLING BUSINESS OPPORTUNITY. TODAY, MOBILE RECYLING PROVIDES A COST- EFFECTIVE SOLUTION TO THE DISPOSAL PROBLEM. ITS ABILITY TO RECYCLE COOLANTS FOR REUSE SAVES THESE COMPANIES THOUSANDS OF DOLLARS EACH YEAR ON COOLANT PURCHASES.
