Aluminum Recycling Facts
Overview
Given the prevalence of curbside pickup and recycling dropoff centers, recycling the aluminum can that contains your soda or the aluminum foil that wraps your brownies often takes only a little effort, but the payoff is big. Because it saves energy, natural resources and money, recycling aluminum instead of consigning it to a landfill benefits consumers, manufacturers and the environment.
Volume
Americans do not recycle as much aluminum as they could. In 2008, 48 percent of the aluminum beverage containers that were created were later recovered, the U.S. Environmental Protection Agency reports. For aluminum containers and packaging, that proportion was lower: 38 percent. Every three months, Americans toss out enough aluminum to recreate all the commercial airplanes in the nation, according to the University of Colorado at Boulder.
Energy Savings
The University of Colorado at Boulder notes that making cans from recycled aluminum rather than virgin ore uses 95 percent less energy. You can power a television for three hours using the energy saved by recycling just one aluminum can. For the same amount of energy that it takes to make a single aluminum can from new ore, you can make 20 recycled aluminum cans.
Cycle
The aluminum recycling process, in which aluminum products from the waste stream are made into new aluminum products, often moves quickly. A can may be manufactured, filled, sold, used, recycled and used to make a new can in as brief a time as six weeks, the EPA notes. An average aluminum can contains about 40 percent recycled metal.
Sources
Aluminum is recycled from numerous sources. Soda and beer cans are the most well known, but aluminum from cars, appliances, doors and windows can also be recycled, the U.S. Geological Survey notes. According to the EPA, used beverage containers and other packaging provide the largest volume of aluminum scrap and diecasts from automobile manufacturing the second largest amount.
History
The process of recycling existing aluminum into new aluminum has been around since the beginning of the 20th century, according to the U.S. Geological Survey. However, aluminum recycling didn't begin to attract widespread public attention until the 1960s, when aluminum can recycling began to take root.
