For example, catalytic converters use platinum which slowly gets lost through exhaust fumes. These chemicals can be extracted from road dust and reused, according to researchers at Cardiff University. This is good news in two ways; energy and land will be saved because of a reduced need to <A href="http://www.treehugger.com/files/2007/03/coal_mining_ret.php">mine</A> for platinum, and because the process will remove these materials from the roads.</blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://www.treehugger.com/files/2007/07/all_sorts_of_na.php"><P>Dr Hazel Prichard of Cardiff University estimates that many kilogrammes of platinum are being sprayed on to streets and roads every year. “Platinum is a vital component not only of catalytic converters but also of fuel cells. Fuel cells are an important new source of clean energy. Platinum is a precious metal and resources are scarce and expensive. Our research is looking at ways of recycling platinum and other precious metals.”</P></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/8F5D5E8F-DB9F-4F4E-987D-4D82A0230FE0/blog/" title="blog or email this clip"><img src="http://content8.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
