Answer 1

Answer: (A), (B), (C)

The correct options are
A Incineration is a waste treatment process that involves the combustion of organic substances contained in waste materials
B Incineration of waste materials converts the waste into ash, flue gas, and heat
C In some cases, the heat generated by incineration can be used to generate electric power.

Incineration is a waste treatment process that involves the combustion of organic substances contained in waste materials.

Incineration and other high-temperature waste treatment systems are described as "thermal treatment". Incineration of waste materials converts the waste into ash, flue gas, and heat.

The heat produced by an incinerator can be used to generate steam which may then be used to drive a turbine in order to produce electricity. The typical amount of net energy that can be produced per tonne municipal waste is about 2/3 MWh of electricity and 2 MWh of district heating.
