High income group generate on average 1.91 kg/capita/day, middle income group generates 1.01 kg/capita/day and low income group 0.92 kg/capita/day.
How does the US process municipal solid waste?
In 2018, 11.8% of MSW generated in the U.S. was disposed of through waste incineration with energy recovery. Combustion reduces waste by 75-85% by weight and 85-95% by volume, leaving behind a residue called ash. A majority of this ash is landfilled, although recent attempts have been made to reuse the residue.
How is the generation of municipal solid waste likely to change in the next 20 years?
How is the generation of municipal solid waste likely to change in the next 20 years? ANSWER: Total municipal waste generation will continue at its current rate. Per capita generation of waste will continue to decline.
Why municipal solid waste is important?
SMM practices conserve resources, reduce wastes, slow climate change and minimize the environmental impacts of the materials we use. In 2013, Americans generated about 254 million tons of trash and recycled and composted about 87 million tons of this material, equivalent to a 34.3 percent recycling rate.
What is the most widely used form of municipal solid waste disposal used in the US?
Sanitary landfills provide the most commonly used waste disposal solution. These landfills are desired to eliminate or reduce the risk of environmental or public health hazards due to waste disposal. These sites are situated where land features work as natural buffers between the environment and the landfill.
What affects waste generation?
Research on factors that affect the rate of waste generation has been carried out by several researchers, the results of the study show that household waste generation is significantly influenced by household size, income, environmental concern, and willingness to separate waste .
What factors affect waste generation?

leaching of nutrients, heavy metals and other toxic compounds from landfills; • use of land for landfills; • emission of greenhouse gases from landfills and treatment of organic waste; • air pollution and toxic by-products from incinerators; • air and water pollution and secondary waste streams from recycling plants; • …
What happens to municipal solid waste?
Of the MSW generated, approximately 69 million tons were recycled and 25 million tons were composted. Together, almost 94 million tons of MSW were recycled and composted, equivalent to a 32.1 percent recycling and composting rate. An additional 17.7 million tons of food were managed by other methods.
What are the three main ways that solid waste is handled in the US?
There a several waste disposal methods available, including landfilling, recycling, and energy recovery. Of the roughly 300 million tons of MSW generated in the U.S. each year, 50 percent is disposed of at landfill sites while less than a quarter is recycled.
