Clean Harbors

Alan S. McKim founded the company in 1980 and retains significant influence as a major shareholder and board member. Day-to-day operations are managed by an experienced executive team overseeing the Environmental Services and Safety-Kleen Sustainability Solutions segments. As a publicly traded company on the New York Stock Exchange, Clean Harbors is governed by a board of directors and follows standard SEC reporting requirements.

Environmental Services generates revenue through a vertically integrated chain of hazardous and non-hazardous waste collection, transportation, treatment, recycling, and disposal at company-owned facilities, alongside industrial and field services such as chemical cleaning, decoking, and spill remediation. Safety-Kleen Sustainability Solutions captures value by re-refining used oil into Group II+ base oils and blending finished lubricants, selling both the recycled base oil and Performance Plus branded products to fleet customers, distributors, and manufacturers.

The company operates more than 100 waste disposal facilities in the United States, including incinerators, landfills, wastewater treatment plants, and recycling centers, plus re-refineries that produce over 150 million gallons of base oil annually. These facilities require extensive environmental permits that are costly and time-consuming to replicate, giving Clean Harbors a structurally protected position in many regional markets.

Clean Harbors is a publicly traded corporation, not a family office or private investment vehicle. While founder Alan McKim holds a significant equity stake, the firm's capital allocation occurs through operational expenditures and corporate M&A rather than through a family office mandate or private fund structure.

Safety-Kleen is a wholly owned subsidiary of Clean Harbors, acquired to expand the company's footprint in used oil recycling and small quantity generator services. The Safety-Kleen Sustainability Solutions segment handles used oil re-refining and finished lubricant blending, while Safety-Kleen Environmental branches provide parts washing, containerized waste collection, and other services aimed at smaller customers that complement Clean Harbors' larger industrial waste management operations.
