What is the main technique of refuse burning that involves burning without prior removal of recyclables?

The main technique of refuse burning that involves burning waste without prior removal of recyclables is mass burning. Mass burning is a method where the entire waste stream is fed directly into the combustion chamber of an incinerator. This process allows for the combustion of mixed solid waste, including materials that may contain recyclables, without any significant preprocessing.

The advantage of mass burning is its efficiency in processing large volumes of waste, reducing the need for extensive sorting and separation that can be time-consuming and costly. By directly burning mixed refuse, it not only helps in waste reduction but also generates energy, which can be harnessed for electricity or heat.

This approach contrasts with other methods that typically involve pre-sorting or preparation of waste before incineration. For example, preparation burning might imply some level of sorting, and controlled burning suggests a more regulated and possibly selective process. Incineration, while certainly relevant to waste management, does not inherently specify the condition of the waste being processed, thus being a broader term that encompasses various techniques, including mass burning.
