What is meant by combustible waste?

Combustible waste refers to solid waste materials that have the capability to burn. This includes various materials that readily ignite and undergo combustion when exposed to fire. Common examples are waste paper, cardboard, and many types of plastics. This type of waste is significant in the context of waste management because it can be used for energy recovery through incineration, which can help reduce the volume of waste sent to landfills while also generating energy.

Other options do not accurately describe combustible waste. For instance, while compostable waste is related to organic materials that decompose biologically, it is not classified as combustible in the traditional sense, as it does not purely relate to burning. Materials that are primarily recyclable may not necessarily be combustible, as their ability to be recycled does not imply they can burn. Lastly, the option that includes waste producing harmful fumes when burned addresses a different concern associated with combustion rather than focusing on the combustibility aspect itself. Thus, the definition of combustible waste is best captured by the materials that can be effectively burned, such as paper, cardboard, and plastics.
