ITEM 2. PROPERTIES
Our principal executive offices are in Norwell, Massachusetts. We own our primary executive office building in Massachusetts which occupies 104,000 square feet. We also currently lease 59,300 square feet of additional office space in Norwell, Massachusetts under arrangements which do not expire until 2042. We have regional administrative offices in Texas, Canada and India. Our properties are sufficient and suitable for our current needs.
We have over 870 operating locations housed at approximately 630 properties covering all 50 states, nine Canadian provinces, Puerto Rico and Mexico. These operating locations include service centers, branches, satellite locations, active hazardous waste management properties and oil processing, blending and packaging facilities. Many of our properties offer multiple capabilities. The following sets forth certain information regarding our key properties as of December 31, 2024.
Service Centers, Branches and Satellite Locations
We have more than 580 service centers, branches and satellite locations, across approximately 462 locations throughout the United States and Canada. These serve as principal sales and service centers from which we provide our environmental, industrial and Safety-Kleen branch core services for our Environmental Services business as well as oil collection and product sales locations for our Safety-Kleen Sustainability Solutions (“SKSS”) business.
Active Hazardous Waste Management Properties
Incinerator Facilities. We own and operate five incinerator facility locations that have a total of ten incinerators, including our new incinerator at Kimball, Nebraska which opened in late 2024. The nine incinerators that were operational during the full year had an overall average utilization of 87.6% on an annual practical capacity of 561,721 tons. Our practical capacity is not based on a theoretical 24-hour, seven-day operation, but rather is determined as the production level at which our incinerators can operate with an acceptable degree of efficiency, taking into consideration factors such as longer term customer demand, permanent staffing levels, operating shifts, holidays, scheduled maintenance and mix of the waste processed. Capacity utilization is calculated by dividing actual production tons by practical capacity at each incinerator. The following table summarizes the practical capacity and utilization for each incinerator for the year ended December 31, 2024:
# of Incinerators Practical Capacity (Tons) Utilization Rate
Year Ended
December 31, 2024
Arkansas (1)
3 160,072 95.9%
Nebraska (2)
2 58,808 86.2%
Utah 1 66,815 97.3%
Texas 3 165,500 77.6%
Ontario, Canada (1)
1 110,526 85.6%
10 561,721 87.6%
_____________________
(1) In 2024, following a review of the waste streams processed at our Arkansas and Ontario facilities, we have increased the capacity in Arkansas by 15,000 tons and reduced the capacity in Ontario by the same amount. These updated amounts are reflected in the table above.
(2) Excludes any tonnage disposed of at our second incinerator which opened in late 2024. For 2025, this incinerator’s practical capacity will increase by 70,000 tons.

Our incinerators offer a wide range of technological capabilities to customers through this network. In the United States, we provide incineration through one fluidized bed thermal oxidation unit and four solids and liquids-capable incinerator facilities, including the new incinerator in Kimball, Nebraska and we operate one active hazardous waste liquid injection incinerator in Canada.
Commercial and Non-Commercial Landfills. In the United States and Canada, we operate seven commercial landfills with approximately 26.4 million cubic yards of remaining highly probable airspace. Six of our commercial landfills are designed and permitted for the disposal of hazardous waste and one landfill is operated for non-hazardous industrial waste disposal and, to a lesser extent, municipal solid waste. In addition to our commercial landfills, we also own and operate one non-commercial landfill that only accepts waste from our on-site incinerator. See “Landfill Accounting” within Note 2, “Significant Accounting Policies,” to our consolidated financial statements included in Item 8 of this report for additional information on our commercial and non-commercial landfills.
Wastewater Treatment Facilities. We operate a total of eleven facilities, of which nine are owned and two are leased, that offer a range of wastewater treatment technologies and services. Wastewater treatment consists primarily of three types of services: hazardous wastewater treatment, sludge dewatering or drying and non-hazardous wastewater treatment.
Treatment, Storage and Disposal Facilities. We operate 33 TSDFs in the United States and Canada, of which 30 are owned and three are leased. Our TSDFs facilitate the treatment and movement of materials among our network of service centers and treatment and disposal facilities. Transportation may be accomplished by truck, rail, barge or a combination of modes, with our own assets or in conjunction with third-party transporters. Specially designed containment systems, vehicles and other equipment permitted for waste transport, together with drivers trained in transportation and waste handling procedures, provide for the movement of customer waste streams.
Other Hazardous Waste Management Properties. We also operate eight facilities specializing in solvent recovery, seven owned and one leased, and we own and operate two autoclave facilities specifically designed to treat medical waste.
Oil Processing, Blending and Packaging Facilities
Oil Terminals. We operate a total of 90 oil terminals, of which 53 are owned and 37 are leased, which collect or process used oil prior to delivery to our re-refineries or distribution as recycled fuel oil.
Oil Recycling and Re-refining Facilities. We own nine oil re-refineries, eight in the United States and one in Canada. Currently our re-refinery in Newark, California is idled; however the location continues to operate as a co-located wastewater treatment, TSDF and oil terminal. The remaining re-refineries have sufficient capacity to continue processing our used oil collections into new re-refined oil, lubricants and byproducts.
Oil Packaging and Blending Facilities. We operate a total of four oil packaging and blending facilities, of which three are owned and one is leased.
