Cardiff University: recycling road dust for precious metals
One potential source for the recovery of platinum is from our own roadways. The team from Cardiff is trying to figure out the best place to find the platinum which is slowly emitted from our own tailpipes from our catalytic converters. One possible source: road cleaners. Sounds a little far-fetched, I know... but it's worth a shot. Like I said, if a reasonable amount can be recovered and recycled, that much less needs to be found in veins in the earth. Now, the researchers say they are hoping to reduce the cost of fuel cells, but more immediate uses would obviously be in more catalytic converters and other exhaust treatment systems which require the metal.
