The amount of lost energy from throwing away recyclable commodities such as aluminum cans and newspapers is equivalent to the annual output of 15 power plants. The energy savings applies to all recycling sectors:

  • Aluminum. Recycling of aluminum cans saves 95% of the energy required to make the same amount of aluminum from its virgin source. One ton of recycled aluminum saves 14,000 kilowatt hours (Kwh) of energy, 40 barrels of oil, 238 million Btu’s of energy, and 10 cubic yards of landfill space.
  • Newsprint. One ton of recycled newsprint saves 601 Kwh of energy, 1.7 barrels of oil (71 gallons), 10.2 million Btu’s of energy, 60 pounds of air pollutants from being released, 7,000 gallons of water, and 4.6 cubic yards of landfill space.
  • Office Paper. One ton of recycled office paper saves 4,100 Kwh of energy, 9 barrels of oil, 54 million Btu’s of energy, 60 pounds of air pollutants from being released, 7,000 gallons of water, and 3.3 cubic yards of landfill space.
  • Plastic. One ton of recycled plastic saves 5,774 Kwh of energy, 16.3 barrels of oil, 98 million Btu’s of energy, and 30 cubic yards of landfill space.
  • Steel. One ton of recycled steel saves 642 Kwh of energy, 1.8 barrels of oil, 10.9 million Btu’s of energy, and 4 cubic yards of landfill space.
  • Glass. One ton of recycled glass saves 42 Kwh of energy, 0.12 barrels of oil (5 gallons), 714,000 Btu’s of energy, 7.5 pounds of air pollutants from being released, and 2 cubic yards of landfill space. Over 30% of the raw material used in glass production now comes from recycled glass.

  • Seattle economist Jeffrey Morris estimated that manufacturing one ton of office and computer paper with recycled paper stock can save nearly 3,000 kilowatt hours over the same ton of paper made with virgin wood products.
  • A ton of soda cans made with recycled aluminum saves an amazing 21,000 kilowatt hours by reducing the virgin bauxite (bozite) ore that would have to be mined, shipped, and refined. That’s a 95% energy savings.
  • A ton of PET plastic containers made with recycled plastic conserves about 7,200 kilowatt hours.
  • The San Diego County Office of Education has figured out that recycling one glass bottle saves enough energy to light a 100 watt light bulb for four hours.
  • The Steel Recycling Institute has found that steel recycling saves enough energy to electrically power the equilvalent of 18 million homes for a year.
