What can be recovered from refuse by burning it in a refractory lined incinerator?

Burning refuse in a refractory lined incinerator effectively recovers energy from the waste material. Incineration transforms solid waste into heat, which can be utilized to generate steam for electricity production or to provide heating for buildings. The process reduces the volume of waste significantly while converting its mass into energy, making it a method that contributes to waste management and energy recovery.

Energy recovery from waste can significantly impact waste disposal strategies, especially in urban areas where landfill space is limited. By harnessing the heat produced during incineration, facilities can operate more efficiently and sustainably.

While the other options—glass, aluminum, and ferrous metal—can also be recovered from refuse, they typically require different recovery processes, such as recycling. In contrast, the primary product recovered by incinerating waste is energy.
