The effects of urban solid waste on global climate change are indisputable. In particular, important greenhouse gas sources such as CO2, including methane emissions from landfills, have significant impacts on climate change. Besides the greenhouse gas effects of waste, it is also an area where doing the right things for the environment is politically popular. For example, it is much easier to establish the way many people manage solid waste than to persuade them to drive fuel-efficiently at a reasonable scale.
Waste management is therefore a promising area where a reduction in carbon emissions can be pursued and should be part of any comprehensive strategy for climate change mitigation.
Waste management has at least five types of impacts on climate change attributable to (1) landfill methane emissions; (2) reductions in industrial energy use and emissions from recycling and waste reduction; (3) energy recovery from waste; (4) carbon sequestration in forests due to reduced demand for virgin paper; and (5) energy used in long-distance waste transport.
After briefly mentioning how important solid waste management is for the whole world and our country, the definitions, management components, classifications, evaluation and management of solid wastes will be mentioned.
