  1. E-Scrap RecyclingCPU Dismantling - Precious Metals • Where found • Circuit boards • Mother board, peripheral cards, processors, memory cards • Constituents • Au, Ag, Pd, Cu, Ni, Pb, Sn, Be, Si, Fe, Bi • Material recovery • Copper smelter • Precious metals recovered at end of copper recovery • Only a few in the world that can handle circuit board scrap in an environmentally sound manner • None in the US.

  2. E-Scrap RecyclingCPU Dismantling - Precious Metals • Smelter • Concentrates come from upgrading ores from mines • 500 lbs ore  1 lb Cu (Value $3 or $0.0060/lb of ore) • 4,000,000 lbs ore  1 lb Au(Value $9300 or $0.0023/lb of ore)Source: Collapse, by, Jared Diamond • Scrap “secondary materials” important feed material • Energy savings – 80% savings compared to concentrates • Sustainability – Scrap replaces mined materials • Precious metals recovered at final stage of base metal process • Operate 24 hr/day –7 day/week –52 wks/yr. • Primary function – create pure base metals from concentrates and scrap.

  3. E-Scrap RecyclingPrecious Metals Materials Copper Smelter Pure Copper Annual Capacity 230,000 tonnes Cu Pure Silver Smelting Furnace

  4. E-Scrap RecyclingHard Drive Destruction • Shred Drives • Protect contained data • Recycle materials • Data erasure (alternative option) • Hard drive resale needed to justify • Time consuming process • Cost associated with software use.

  5. E-Scrap RecyclingSteel, Aluminum,Wire Source: • Computer cases, connection cables, etc. • Sort in to material type: Al, Steel, Cu, Cu wire… • Market through scrap metal dealers. • Major markets – Asia Pacific and India .

  6. E-Scrap Recycling Hazardous Materials Hazardous material • Batteries • Nickel Cadmium • Lithium Metal • Nickel Metal Hydride • Hazardous characteristic • Flammability • Location • Motherboard • Handling • Isolate to avoid shorting/fire • Processed at licensed facility • Metech audits facilities per ISO 9001 procedures.
