Composition of generated MSW can be categorized into organic and inorganic.
Organic fraction of the waste mainly includes food wastes (mixed), plant materials, paper and cardboard, textile and gunny bags, animals’ wastes and decomposed
garbage, etc. (Table 1, Fig. 2) [34]. Whereas, inorganic fraction of MSW encapsulates construction wastes, plastics, glass, metals, rubber, thermacole, electronic
wastes (e-waste), multilaminates, ashes, and other processed trashes having inorganic constituents (Table 1, Fig. 2). Percentage contribution of both organic and
inorganic fractions in MSW generated from different areas of the world is illustrated
in Table 2 [44]. Composition of MSW is greatly influenced by geographical locaTables 1 Sources of organic and inorganic constituents in municipal solid waste
