The principal advantage of incineration for municipal solid waste is that it:
Correct answer: B. Greatly reduces waste volume through controlled combustion
- A. Converts all waste into harmless drinking water
- B. Greatly reduces waste volume through controlled combustion
- C. Eliminates the need to control air emissions
- D. Produces compost without requiring biodegradable material
Explanation
Controlled combustion can substantially reduce the volume of municipal solid waste and may also recover energy. Incinerators still require air pollution controls, and their ash needs proper management.

About Environmental Engineering
Environmental engineering examines water supply, water quality, treatment processes, wastewater collection and treatment, solid waste management, air pollution and public health protection. It covers sedimentation, coagulation, filtration, disinfection, biological treatment and disposal methods, while distinguishing drinking-water treatment from sewage treatment and BOD from COD.
