Metal Recycling

Metal Recycling

Scrap metal makes up one of the two largest exports that the U.S. sends to China. In fact, according to the Institute of Scrap Recycling Industries (ISRI) there are “150 million metric tons of scrap materials recycled annually including: 81.6 million tons of iron and steel, 5 million tons of aluminum, 1.8 million tons of copper and 2 million tons of stainless steel.” In addition to these metals, others metals can also be recycled including:

  • Brass and Bronze
  • Zinc
  • Magnesium
  • Tin
  • Lead

The amount of energy saved in using recycled metals is extensive. The ISRI reports an energy use reduction of 95 percent for aluminum, 85 percent for copper and 74 percent for iron and steel. As far as conservation goes, using recycled goods for metal products can make a big impact. Steel conserves 2500 lbs. of iron ore, 1400 lbs. of coal and 120 lbs. of limestone, while aluminum conserves up to 8 tons bauxite ore and 14 megawatt hours of electricity.

How to Recycle Metal

Scrap metal includes ferrous metals (iron and steel) and nonferrous materials (aluminum, copper, tin, brass). Many of our home appliances are made of metals. This includes our washers & dryers, refrigerators, ovens & stoves and water heaters. Waste from unwanted appliances can be categorized in two main types: refrigerants (Freon) and non-refrigerants.

The Process

The recycling process for metal is similar to those of other materials. It is best described in four stages:

  1. Collection
  2. Processing
  3. Shredding
  4. Selling

After collection and proper sorting, the scrap is compacted. It is then sold to minimills, which process them to steel. According to RecycleMetal.org, “processing scrap metal to steel instead of virgin ore require about 74 percent less energy.”

Tips for Recycling

  • Have the delivery company for your new appliance, take the old with them. These companies can either recycle the unit or properly dispose of it
  • Have a professional disassemble your appliance and take the appropriate materials to recyclers in your area
  • If the appliance is still working, sell it on online, donate it to ta charity or give it to a friend
