Municipal Solid Waste(MSW) contains a large amount of recyclable and reusable materials, such as high calorific value combustible materials that can be prepared into alternative fuels (RDF, SRF) to reduce the use of coal, organic materials that can be made into compost or used for digester fermentation, and high value recyclables such as plastics, glass, metals and waste paper that can be directly reused or made into raw materials.
