There is no national law in the United States that mandates recycling, and state and local governments often introduce their own recycling requirements. In 2014, the recycling/composting rate for municipal solid waste in the US was 34.6%. A number of U.S. states, including California, Connecticut, Delaware, Hawaii, Iowa, Maine, Massachusetts, Michigan, New York, Oregon, and Vermont have passed laws that establish deposits or refund values on beverage containers while other jurisdictions rely on recycling goals or landfill bans of recyclable materials.
