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.
