Some examples of recyclable resources are newspapers, cardboard, office paper and glass. Other recyclable resources include plastic, aluminum and steel. Many major cities in the United States have recycling programs as well as programs to collect yard and hazardous waste.
Besides paper, plastic, glass and metal, many other resources can be recycled. Some less commonly known recyclable resources are bricks, asphalt, concrete, oil and sand. These less commonly known resources should be taken to special centers that recycle them and placed in the blue bins that cities provide for regular recycling purposes.
Many major U.S. cities also have programs to collect and recycle organic materials, as when collecting yard waste for composting. Composting speeds up the decomposition process in organic materials with the resulting materials used to feed plants. Santa Barbara, California, for example, collects yard waste in green bins it provides to its residents, and then composts the materials. Yard waste includes leaves, twigs and dried-up plants. In addition, as of 2013, Staten Island, a small municipality in New York City, began collecting food waste to turn it into fertilizer. As of 2015, New York City is working to expand the program due its environmental and economical benefits. San Francisco leads the nation with its own organic waste recycling programs as of 2013; an estimated 78 percent of San Francisco's organic waste is recycled.
