-temperature combustion destroyed greater than 99.9999% of PFAS compounds, a level that meets the strict chemical destruction standards for many of the most dangerous and difficult to destroy hazardous wastes. As the prevalence of PFAS and the necessity to mitigate future harm from these “forever chemicals” becomes more widely understood and demand for services to properly handle and dispose of these materials increases, we believe this capability will become a differentiating factor for us. As mentioned, our Total PFAS solutions is a comprehensive program where our team can guide customers through the process of testing, treatment and final disposition and destruction of the PFAS contaminants.

When providing environmental services, we are committed to the recycling, reuse and reclamation of handled waste streams whenever practical using a variety of methods more fully explained in the sections describing our general operations. Many of our branded services exemplify our commitment to sustainability and providing environmental solutions to the marketplace. Where possible, liquids such as solvents, chemicals and used oil are continuously recycled to industry standards and made into useful and sustainable products. Tolling programs provide a closed-loop process in which the customer’s spent solvents are recycled to precise specifications and returned directly to the customer. Across our facilities we look for cost-saving and recycling initiatives to enhance efficiency of our waste-handling systems. For example, our El Dorado, Arkansas, facility now has the capability to recycle and reconstitute polycarbonate containers resulting in producing more than 400,000 recycled plastic containers at the site in 2024. Additionally, we are employing artificial intelligence and route optimization in our service delivery to save on fuel and reduce emissions.

Our Safety-Kleen OilPlus® Program is designed to help companies manage their oil related disposal and consumption needs in a more sustainable way. Environmental regulations prohibit the disposal of oil in sewers or landfills as improper disposal can lead to widespread environmental problems. To avoid the improper disposal of oil, we deploy our fleet of trucks, tankers, rail-cars and barges to collect used oil. In 2024, we gathered more than 253 million gallons of used oil in North America. This used oil is feedstock into our re-refining process which extends the life of crude oil resources. Not only does this outlet reduce the likelihood of improper oil disposal but also it decreases overall energy usage as, per the Department of Energy, it can take less energy to recycle used oil than to create new lubricating oil from virgin crude oil.

Our state-of-the-art re-refining processes enable us to fully realize oil’s remarkable
