Which statement about incineration as a treatment method is true?

Which statement about incineration as a treatment method is true?

• A. It is true that incineration thermally destroys organics and reduces waste volume, and includes air emissions controls.
• B. It always produces more waste volume.
• C. It requires no permits.
• D. It does not require monitoring.

Answer: (A)

Incineration uses high-temperature combustion to destroy organic components in waste, which both chemically neutralizes the organics and significantly reduces the volume of waste that remains as ash. Because burning can release pollutants, the process must include air emissions controls to limit releases of substances like particulates, acid gases, and other contaminants. In addition, hazardous waste incinerators operate under regulatory permits and are subject to ongoing monitoring and testing to ensure compliance with emission limits and proper waste-feeding and operation. That combination—thermal destruction of organics, substantial volume reduction, and required emissions controls—is what makes this statement true. The other options are incorrect because incineration does not always increase waste volume, and it does require permits and monitoring.
