B. 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.
