Clean Harbors (CLH)

The business is organised around two main segments: Environmental Services and Safety-Kleen Sustainability Solutions. Environmental Services is the larger contributor and includes waste collection, transportation, treatment, recycling, disposal, emergency response, and industrial maintenance. These services are used by manufacturers, chemical companies, refineries, utilities, healthcare organisations, and other customers that must handle regulated materials safely and reliably. Clean Harbors’ network of disposal and treatment assets is a key competitive advantage because such facilities are difficult to permit, build, and replace.

Safety-Kleen Sustainability Solutions focuses on used oil collection, re-refining, parts cleaning, and related products. Through this unit, the company collects used motor oil and other fluids, processes them into base oils, vacuum gas oil, and lubricants, and provides services to automotive shops, fleet operators, and industrial customers. This gives Clean Harbors exposure to circular economy and resource recovery trends, as well as traditional environmental compliance demand.

Clean Harbors is distinctive because it combines field services, waste infrastructure, recycling capabilities, and specialised environmental expertise under one platform. Its performance is influenced by industrial activity, regulatory enforcement, waste volumes, energy markets, and customer demand for sustainable waste management and materials recovery services.
