Clean Harbors, Inc. was incorporated in 1980 and is headquartered in Norwell, Massachusetts.

Clean Harbors, Inc. was founded in 1980 in Brockton, Massachusetts, a Boston suburb, by Alan S. McKim, who continues as the company's CEO and Chairman. The company had one truck and four employees who transported and disposed of hazardous wastes for local businesses. It soon began adding larger corporate accounts and grew to 18 employees and $1.5 million in revenues by the end of its second year. In year three its revenue increased to $4.2 million and 34 employees.

Clean Harbors expanded to offer emergency hazardous waste cleaning services and industrial waste disposal, as well as ongoing management of hazardous material sites. Revenues continued to climb approaching $50 million in 1986.

Expansion and diversification

Clean Harbors held its initial public offering offering of one million shares at $9 a share on the NASDAQ on November 24, 1987. Six months later Clean Harbors' stock had risen from $9 to more than $15. The company made a secondary offering at the higher share price. After the two tranches Alan McKim retained about 60 percent ownership of Clean Harbors.

Going public set the stage for expansion. Clean Harbors, still solely an environmental services company, purchased Occupational Safety and Health Administration Resource Conservation and Recovery Act certified hazardous waste incinerators in Arkansas, Nebraska, Ontario, Quebec, Texas and Utah, which it continues to own and operate to this day.

During this time Clean Harbors also developed its emergency response capabilities. Its first project came in 1984 when it removed oil from a tanker, which foundered off Cape Cod in a snowstorm. It participated in several cleanup projects in New England and expanded to respond to emergencies outside of the region as well as handling industrial and land-based cleanup and transportation projects.

During this time the company also greatly expanded its services for the industrial and chemical industry sectors. These services focused on collecting, packing and disposing of industrial and research laboratory and production chemicals, many of which were disposed of through Clean Harbors' expanding network of RCRA-certified landfills and incinerators. In 1998, Clean Harbors Industrial Services was established as division to handle in-plant cleaning and maintenance services, including chemical cleaning, vacuuming, steam cleaning and hydroblasting of chemical processing equipment.

Over the years Clean Harbors has continued to expand through organic growth and approximately 35 acquisitions. Most of the acquisitions were relatively small compared to Clean Harbors’ overall revenues. Major acquisitions, such as Eveready, Inc., Peak Energy Services, Teris LLC and most notably, Safety-Kleen Systems, their best acquisition to date, have substantially added to the company's assets and broadened its service lines to include industrial and energy services, solvent recovery/recycling, lodging and oilfield and environmental dewatering technologies.

Today, Clean Harbors has a substantial presence in oil and gas oilfields and refinery operations and used oil recycling and re-refining while maintaining and growing its environmental and industrial services business lines.
