Municipal solid waste management involves not only the reduction of environmental and health effects, but also the reduction of natural resources use. Therefore, reusing and recycling become important to reduce waste generation and its improper disposal, greenhouse gas emissions, and the use of energy and water for natural resources extraction. These actions result in significant economic, social, and environmental benefits.
As mentioned by the World Bank in its What a Waste 2.0: A Global Snapshot of Solid Waste Management to 2050 report, about 2.01 billion metric tons of municipal solid waste were produced worldwide in 2016. Moreover, the World Bank estimates that waste generation will increase to 2.59 billion metric tons by 2030 and to 3.4 billion metric tons by 2050.
