Heating of air, gas, or gas mixture up to 9032 degrees F for the thermal destruction of hazardous wastes describes a process called:

The process described, which involves heating air, gas, or a gas mixture to extremely high temperatures (up to 9032 degrees Fahrenheit) for the purpose of thermally destroying hazardous wastes, is known as plasma technology.

Plasma technology utilizes high-energy arcs to create plasma, which can reach temperatures much higher than traditional combustion methods. This high-temperature environment enables the complete decomposition of hazardous materials, breaking them down into simpler, non-toxic components. The efficiency of plasma technology in destroying a wide range of waste materials, including those that are difficult to incinerate using conventional techniques, makes it an advanced method for hazardous waste management.

While rotary kiln incineration and fuel blending are also processes related to hazardous waste treatment, they do not involve heating materials to the extreme temperatures characteristic of plasma technology. Rotary kilns operate at lower temperatures and are primarily used for incineration, whereas fuel blending refers to the mixing of waste materials with fuels to optimize combustion rather than achieving the plasma state. This distinction highlights why plasma technology is the most fitting answer to the question regarding hazardous waste thermal destruction at such high temperatures.
