Municipal solid waste (MSW) management is a major problem in world today. Current global MSW generation
levels are approximately 1.7-1.9 billion metric tonnes per year, and are expected to increase to approximately 2.8
billion tonnes per year by 2025. MSW generation rates are influenced by economic development, the degree of
industrialization, public habits, and local climate. A significant amount of debris resulting from various activities is
currently disposed of in landfills. Landfilling of this debris results in a large burden on the world’s natural resources
and an increasingly expensive problem for solid waste management. Currently, the transportation industry is under
increasing pressure to use alternate or secondary materials because of its high-volume consumption of bulk materials
(such as natural fine and coarse aggregates) in road construction. Materials including industrial by-products,
concrete aggregates, old asphalt pavement, scrap tyres, fly ash, steel slag, and plastics are often used as alternate
materials for natural aggregates.
