Cash For Scrap Metal

The most common metals to consider when discussing recycling are aluminum (Al) and steel. Some other metals–like Au, Ag, brass, and Cu–are so valuable that they are rarely thrown away. They do not create a waste disposal problem.

Aluminum and steel do. Americans use 100 million steel cans and 200 million aluminum beverage cans every day (300,000,000 metal cans). What should we do with this metal waste? Should we burn it in waste-to-energy plant? Should we landfill it? Or should we recycle it?

After source reduction (using less aluminum to make a can, for example), recycling is the most efficient way to reduce aluminum and steel waste.

Unlike paper and plastics, burning metal trash in waste-to-energy plants creates no energy. Instead, aluminum melts and steel just gets very hot. Magnets can be used to collect steel scrap at waste-to-energy plants, though, and then the scrap can be shipped to steel plants for recycling.

Landfilling is usually not a good alternative either. Aluminum, in particular, is so valuable as a scrap material that it simply does not make sense to bury it.

this saves 155% of energy and 95% of air pollution

Scrap metal includes ferrous metals (iron and steel) and nonferrous materials (Al, Cu, Sn, 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, “processing scrap metal to steel instead of virgin ore require about 74 percent less energy.”

  1. Cans are first divided from municipal waste, usually through an eddy current separator, and cut into little, equal pieces to lessen the volume and make it easier for the machines that separate them.
  2. Pieces are cleaned chemically/mechanically, and blocked to minimise oxidation losses when melted. (The surface of metal readily oxidizes back into metal oxide when exposed to oxygen.).
  3. Blocks are loaded into the furnace and heated to 2800 °F to produce molten metal.
  4. Dross is removed and the dissolved hydrogen is degassed. (Molten metal readily disassociates hydrogen from water vapor and hydrocarbon contaminants.) This is typically done with chlorine and nitrogen gas. Hexachloroethane tablets are normally used as the source for Cl. Ammonium perchlorate can also be used, as it decomposes mainly into chlorine, nitrogen, and oxygen when heated.
  5. Samples are taken for spectroscopic analysis. Depending on the final product desired, high purity metal, copper, zinc, manganese, silicon, and/or Mg is added to alter the molten composition to the proper alloy specification. The top 5 metal alloys produced are apparently 6061, 7075, 1100, 6063, and 2024.
  6. The furnace is tapped, the molten metal poured out, and the process is repeated again for the next batch. Depending on the end product it may be cast into ingots, billets, or rods, formed into large slabs for rolling, atomized into powder, sent to an extruder, or transported in its molten state to manufacturing facilities for further processing.
