High-Temperature Hazardous Waste Incineration in the United States
There are 22 RCRA-permitted hazardous waste incinerators operating in the United States, with three also holding TSCA permits for PCB destruction. The market is heavily consolidated: Clean Harbors controls over 60% of North America's incineration capacity, while Veolia North America operates the only U.S. facility permitted to destroy all three categories — hazardous waste, PCBs, and dioxins.
Key Operators and Facility Profiles
| Operator | Facilities | Notable Capability |
|---|---|---|
| Clean Harbors | Deer Park TX, El Dorado AR, Kimball NE, Aragonite UT | 60%+ of North American capacity; Aragonite processes ~60,000 tons/yr via slagging rotary kiln |
| Veolia North America | Port Arthur TX, Gum Springs AR, Sauget IL | Only U.S. facility permitted for dioxin destruction (Port Arthur); 6 incinerators across 3 sites |
| Ross Environmental | Grafton, OH | One of the first commercial incinerators in the U.S.; operating since 1949 |
Operating Temperature Standards
RCRA-regulated incinerators typically operate between 1,200°F and 3,000°F in the primary combustion zone. The EPA's MACT (Maximum Achievable Control Technology) standards mandate both emission limits and operating parameters, including minimum/maximum temperature ranges. Facilities must demonstrate a 99.99% destruction and removal efficiency (DRE) for principal organic hazardous constituents — rising to 99.9999% ("six nines") for dioxin-bearing wastes.
Waste Streams and Selection Criteria
When selecting an incinerator operator, EHS managers should evaluate:
- Permit scope
- Not all facilities accept the same waste codes. TSCA-permitted facilities are required for PCB wastes above 50 ppm. Only Veolia Port Arthur holds a dioxin destruction permit.
- Logistics and proximity
- Hazardous waste transportation adds cost and DOT compliance burden. Clean Harbors' geographically distributed network (TX, AR, NE, UT) reduces average haul distance.
- Throughput and scheduling
- Capacity constraints can create multi-week queues. Facilities like Kimball (45,000 tons/yr fluidized bed) or Aragonite (13 tons/hr rotary kiln) serve different volume profiles.
