Clean Harbors, Inc. is a comprehensive provider of environmental and industrial services, operating primarily in the United States and Canada. The company's business model is built around managing the lifecycle of hazardous and non-hazardous waste, from collection and transportation to treatment, recycling, and disposal. Clean Harbors operates through two primary segments: Environmental Services (ES) and Safety-Kleen Sustainability Solutions (SKSS).
The Environmental Services segment is the core revenue driver, accounting for approximately 84% of total revenues (which reached $5.89 billion in 2024). This segment provides technical services such as hazardous waste management, incineration, and landfill disposal, alongside field services like emergency spill response and industrial cleaning. The company's extensive network of waste management facilities creates high barriers to entry and supports its competitive position.
The Safety-Kleen Sustainability Solutions segment generates the remaining 16% of revenues and operates as a large-scale collector, re-refiner, and recycler of used oil. This segment manufactures base oil, vacuum gas oil, and blended lubricants, providing a closed-loop model for automotive and industrial customers. Clean Harbors serves a highly diversified customer base across the chemical, manufacturing, refining, and automotive industries, as well as government agencies. The company's vertically integrated infrastructure and regulatory expertise make it a key partner for organizations navigating complex environmental compliance requirements.
