While it’s better to reduce waste by refusing or reusing, recycling does conserve energy and natural resources and reduces air and water pollution. Extracting raw materials, processing them into components, and manufacturing new items is much more costly than recycling and reusing materials. In fact, recycling one ton of office paper can save the energy equivalent of 322 gallons of gas; recycling one ton of aluminum conserves the equivalent of 1,024 gallons of gas! Recycling just 10 plastic bottles saves enough energy to power a laptop computer for more than 25 hours. Recycling materials avoids emissions and saves water.
