CLH

Clean Harbors, Inc

A North American environmental and industrial services company that collects, treats, and disposes of hazardous and non-hazardous waste, and through its Safety-Kleen arm re-refines used oil into fresh base oil and lubricants for manufacturers, refineries, and others. It began in 1980 when Alan McKim started a four-person tank-cleaning business in the Boston area with a single truck. One of its early jobs was cleaning up the 1984 oil spill from the beached tanker Eldia off Cape Cod, helping launch its emergency-response reputation.
