While in former times steel was produced exclusively from ore, steel today has a scrap content of more than 50 percent. And not only iron can be recycled. Refrigerators, mobile phones, radios, computers, fax machines, or washing machines, however, cannot be re-used as a whole, but only after they have been classified into mono-material fractions. High-performance separating and sorting systems are required to ensure that recycling provides best possible mono-fraction materials that can be profitably fed back into the material cycle.

End-of-life vehicles, either disassembled or as a whole, are shredded. The separation and sorting of the material mixture from car shredders makes it possible to recycle the used plastics, metals, and other materials.

In the EU region alone there are several million tons of waste electrical and electronic equipment that is no longer used and must therefore be scrapped every year. Due to increasingly shorter life cycles and to the trend to use more electronics equipment in private life and in the commercial sector, the amount of e-waste is permanently growing. Since electronic equipment contains many different materials, recycling requires highly sophisticated separation and sorting technologies. The recovery of precious metals, other kinds of metals, and plastics makes e-waste recycling profitable.

Metal is almost 100 % recyclable. Metal separators and sorting systems provide mono-material metal fractions. While many other materials show a clear deterioration of quality when they are recycled, the recycling of metal scrap again and again results in products of the same high quality.
