Clean Harbors Inc Dossier
Qualitative Analysis
Business overview
Clean Harbors, Inc. (NYSE: CLH) is North America's leading provider of environmental, industrial, and waste management services. Founded in 1980, the company operates a vast network of waste disposal facilities, including commercial incinerators, landfills, wastewater treatment plants, and solvent recycling centers. Clean Harbors operates through two primary business segments: Environmental Services (ES) and Safety-Kleen Sustainability Solutions (SKSS). The Environmental Services segment collects, transports, treats, and disposes of hazardous and non-hazardous waste, alongside providing specialized industrial maintenance services. The Safety-Kleen Sustainability Solutions segment focuses on parts cleaning, containerized waste services, used motor oil collection, and the manufacturing and sale of high-quality base and blended lubricants. The company's extensive, highly permitted infrastructure represents a significant competitive moat, as permitting new hazardous waste facilities in North America is exceptionally difficult.
