Scrap - An Excellent Raw Material

Abstract

As the dramatically increasing prize for energy and also for raw materials shows we all are familiar with the prognoses of the Club of Rome: All raw materials on earth are limited and have a more or less long period until they are exhausted. Another type of source for metals like iron, copper, nickel, silver or gold has grown up more and more within the last 10 years in Europe. Secondary raw materials as basis for the production of those metals are getting more significance in Europe and northern America as well as in Japan. But increasing amount of scrap leads to increasing environmental problems in terms of collection and process-ing of scrap.
