Furthermore,addition to these requirements, a sustainable system for solid waste managementmust be environmentally effective, economically affordable and sociallyacceptable.1.Environmentally effective: the wastemanagement system should minimize as much as possible the environmental burdensof waste management (emissions to land, air, and water)2. Economicallyaffordable: the waste managementsystem should operate at a cost-effectively, which includes all stakeholder. However,the costs of operating of waste management system will depend on the incomelevel of the country, state or region.

But probably it should be less or nomore than current waste management costs.3. Sociallyacceptable: the waste managementsystem must operate in a manner that is acceptable for the majority ofstakeholders in the society.1.2.3       WastehierarchyThe Waste Hierarchy sets out a hierarchy of optionsfor managing waste in terms of minimize non-renewable resource depletion,improve air and water quality, to build up greener economy and as a solutionfor the climate change.
