 toxic properties and other substances subject to federal, state and provincial environmental regulation. We provide final treatment and disposal services designed to manage waste which cannot be otherwise safely and/or economically recycled or reused. The waste that we handle comes in solid, sludge, liquid and gas form.

Incineration is the preferred method for the treatment of organic hazardous waste because it effectively destroys the contaminants at high temperatures. High temperature incineration safely and efficiently eliminates organic waste such as herbicides, halogenated solvents, pesticides and pharmaceutical and refinery waste, regardless of form as gas, liquid, sludge or solid. Federal and state incineration regulations require a destruction and removal efficiency of at least 99.99% for most organic waste and our incinerators meet or exceed these requirements.

As of December 31, 2024, we operated ten active incinerators at five facilities that offer a wide range of technological capabilities to customers. Our incinerator facilities in the United States are designed to process waste through the use of high-tech, high temperature incineration. Our technologies include rotary kiln incineration, which provides greater flexibility in destruction of hazardous waste, and fluidized bed incineration which helps promote a more complete organic combustion than other incineration technologies. Our incinerator facility in Lambton, Ontario, is a liquid injection incinerator designed primarily for the destruction of liquid organic waste. Typical waste streams at this location include wastewater with low levels of organics and other higher concentration organic liquid waste not amenable to conventional physical or chemical waste treatment. For 2024, our facilities operated with an annual practical capacity of 561,721 tons. With the opening of our new incinerator in Kimball Nebraska, this annual practical capacity will increase by 70,000 for 2025 and beyond.

Landfills are primarily used for disposal of inorganic waste. In the United States and Canada, we operate seven commercial landfills, six of which are designed and permitted for disposal of hazardous waste and one which is operated for non-hazardous industrial waste disposal. Of our six commercial hazardous waste landfills, four are located in the United States and two are located in Canada. Our non-hazardous landfill is located in the United States. In addition to our seven commercial landfills, we also own and operate one non-commercial landfill that only accepts waste from our Kimball on-site incinerator, as described above.

 As of December 31, 2024, the useful economic lives of our six commercial hazardous
