No future without scarce metals
Date:1/31/2012

largest recycling companies involved in the recovery of precious metals from complex waste material. Recycling scarce metals demands the use of complicated recovery processes.

Furthermore, suitable recovery processes alone are not enough to guarantee high recycling rates. According to the experts it is necessary to keep an eye on the whole recycling chain, from collection, disassembly and sorting of the scrap to the actual recovery process itself. The greatest efforts are in vain if, as is the case in certain countries, end-of-life computers and other electronic appliances are exported to developing and threshold countries where the scarce metals are lost through the inappropriate treatment of the electronic waste, which also represents a danger to human health and the environment. Or, if with a mechanical disassembly - which is common today in Switzerland the scarce metals are dissipated into fractions from which they cannot be recovered.
