Abstract: A method of recovering the metal from automobile scrap and electronic waste. It includes separating the automobile scrap and the electronic waste to provide some metal pieces, washing and/or shredding and/or selecting said metal pieces to provide some groups of metal pieces having the same metal element, making a full-elemental analysis, comparing the weight of different metal pieces having the same metal element and attaining different combinations of value, weighted averaging the combination of value to calculate the full-elemental weighted average according to the different combinations of value, comparing the different full-elemental weighted averaging to different composite material, and finding a optimal set or some optimal sets, further disposing metal pieces according to the optimal set, and manufacturing alloy. Present invention has a lot of advantages, such as reducing pollution and cost, and processing more waste.

Abstract: A method of using scrap rubber, such as tires, parts of tires or shredded tires, to manufacture or melt steel and other metals in a furnace is disclosed. The scrap rubber may be used as a carbon source for the manufacture of steel and other metals, and may be used as an energy source to melt the scrap metal used to make the steel and other metals. The net benefit of this method includes reducing the amount of scrap rubber, such as tires, to be sent to waste disposal facility or landfill, thereby improving the environment. In addition, by increasing the use of scrap rubber as a source of energy for steel or metal production, less energy is required from other sources.
