Mixed waste can also be defined as a type of waste which includes recyclable materials and organic materials. [21] Some examples of mixed waste in this context include a combination of broken glassware, floor sweepings, non-repairable household goods, non-recyclable plastic and metal, and clothing and furnishings. Additionally, ashes and soot ...
Landfill fire. A landfill fire occurs when waste disposed of in a landfill ignites and spreads. Two types of landfills fires are generally recognized – surface fires and deep-seated fires.

Incineration is a waste treatment process that involves the combustion of substances contained in waste materials. [1] Industrial plants for waste incineration are commonly referred to as waste-to-energy facilities. Incineration and other high-temperature waste treatment systems are described as "thermal treatment". Incineration of waste ...
'Repurpose' and 'Recycle' involve maximum usage of the materials used in the product, and 'Recover' is the least preferred and least efficient waste management practice involving the recovery of embedded energy in the waste material. For example, burning the waste to produce heat (and electricity from heat).
Combustibility and flammability. A combustible material is a material that can burn (i.e., sustain a flame) in air under certain conditions. A material is flammable if it ignites easily at ambient temperatures. In other words, a combustible material ignites with some effort and a flammable material catches fire immediately on exposure to flame.
