Clean Harbors, Inc. provides environmental and industrial services to commercial, industrial, and government customers in North America. The company operates through segments including Environmental Services (hazardous waste disposal, emergency response, industrial cleaning, waste management) and Safety-Kleen Sustainability Solutions (parts cleaning, used oil collection and re-refining, containerized waste services). Clean Harbors collects, treats, and disposes of hazardous and non-hazardous waste, provides emergency spill response, industrial cleaning and maintenance, and operates waste treatment and disposal facilities. Founded in 1980 and headquartered in Norwell, Massachusetts, Clean Harbors has built North America's largest environmental services network through organic growth and strategic acquisitions including Safety-Kleen. The company benefits from essential services, regulatory requirements driving demand, recurring customer relationships, integrated disposal capabilities, and high barriers to entry including permits and specialized assets. Clean Harbors generates stable revenues across economic cycles with growth tied to industrial production and environmental incidents. The company faces regulatory risks, competitive pressures, waste volume variations, and capital intensity. Clean Harbors continues to invest in capabilities, expand services, and pursue operational efficiencies.
