<strong>Recycling</strong> <strong>critical</strong> <strong>raw</strong> <strong>materials</strong> <strong>from</strong> <strong>waste</strong> <strong>electronic</strong><br />

100 t/a and in the case of indium, around 600 t/a, UNEP 2009) and the generally dissipative<br />
applications i.e. relatively small quantities of these metals are contained per product unit.<br />
This places very high demands on recycling systems and technologies. Nevertheless, the<br />
recycling of gallium and indium <strong>from</strong> processing residues is established in e.g. Japan but<br />
also in Germany (UNEP 2009, PPM 2011). The recycling of gallium and indium <strong>from</strong> <strong>waste</strong><br />
<strong>electronic</strong> fractions studied in this project is currently not possible as the relevant<br />
technologies are lacking. However, suitable research and development projects are likely in<br />
the near future.<br />
