Step-by-step explanation:
Municipal Solid Waste in the United States
In the United States, the largest single component of municipal solid waste (MSW) is typically food waste. According to the Environmental Protection Agency (EPA), more than 40 million tons of food waste were generated in 2017, making up 15.2% of all the trash sent to landfills. The composition of MSW can vary, but for a well-developed waste recycling system, the waste stream primarily consists of intractable wastes such as plastic film and non-recyclable packaging materials. Other common components include plastics, paper, yard wastes, and other miscellaneous solid wastes from various sources. Strategies for waste management are crucial for controlling ground pollution and include reducing, reusing, and recycling to minimize the impact on landfills and facilitate a safer, cleaner environment.
