Question

Which of the following is the method of controlled aerobic combustion of wastes inside chambers at temperatures as high as 900${}^0$-1300${}^0$C?

• A. Sludge burning
• B. Pyrolysis
• C. Incineration
• D. Source reduction

Answer 1

The correct option is C Incineration

Incineration is the process of oxidation of combustible substance present in the waste (which is heterogeneous material like minerals, metals etc.). The waste is treated to reduce its volume, convert that into useful form of energy. At a temperature of 900 to 1300${}^0$ C, the organic substances in the waste will burn and release energy. So, the correct answer is 'Incineration'.
