Operators of well-run landfills for non-hazardous waste meet predefined specifications by applying techniques to: [1] confine waste to as small an area as possible; compact waste to reduce volume [2] They can also cover waste (usually daily) with layers of soil or other types of material such as woodchips and fine particles.
In 2010, Americans recovered almost 65 million tons of MSW (excluding composting) through recycling. [1] Despite an increase in population, the total amount of solid waste disposed in landfills has decreased since 1990.

[64] [65] [66] Los Angeles defines zero waste as "maximizing diversion from landfills and reducing waste at the source, with the ultimate goal of striving for more-sustainable solid waste management practices." Los Angeles plans to reach this goal by the year of 2025.
Energy recovery from waste is the conversion of non-recyclable waste materials into usable heat, electricity, or fuel through a variety of processes, including combustion, gasification, pyrolyzation, anaerobic digestion, and landfill gas recovery. [51] This process is often called waste-to-energy.
However, due to the dye used, black plastic food containers are typically considered non-recyclable, along with all takeout containers labeled #5 or #6. 4. Plastic Wrap and Storage Bags
Federal regulations in the United States require a minimum of six (6) inches of daily cover to be used at the end of each day.

Over 100 million computers, monitors, and televisions are disposed of yearly in the U.S. [8] Although there is an enormous amount of electronic waste in the United States, the Environmental Protection Agency found that in 2009 approximately only about 25% of all electronic waste is recycled in the United States.
