Collects and processes hazardous and non-hazardous waste while providing industrial cleaning, maintenance, field, and emergency-response services. A smaller Safety-Kleen business gathers used oil and re-refines it into base oil and lubricants, while route-based parts-cleaning services and owned processing assets anchor the broader North American network.
Collects, transports, treats, recycles, and disposes of hazardous and non-hazardous waste through Environmental Services, which also provides industrial cleaning, maintenance, field services, and emergency response across North America.
Safety-Kleen Sustainability Solutions collects used oil and related automotive fluids, re-refines them into base oil and blended lubricants, and provides parts-cleaning services. Environmental Services supplies most revenue, while the Safety-Kleen network adds route-based collection and circular oil processing.
Execution rests on route density and the ability to direct collected material into owned treatment, disposal, and re-refining assets. Operations depend on permits, environmental compliance systems, specialized labor, and safe facility maintenance; Safety-Kleen results also respond to base-oil and blended-oil pricing and collection economics.
