ATMI has developed eVolv, a very interesting technology for recycling e-waste, essentialy separating out the precious metals for reinserting back into the productive economy as raw materials:
The process is completed in a closed-loop system using a series of chemical baths, and desoldering techniques which reclaim much of the precious metal components for reuse. This technique is 99 percent sustainable, and can be implemented locally, directly in a manufacturer's warehouse. This approach also helps to relieve the global issue of e-Waste being broken down in poorer regions of the world where it affects human welfare, and the environment.
This was announced almost a year ago, however the eVolve website doesn't give any case studies of where the technology has been deployed. Perhaps something worth watching.
