Manufacturing

• Glass
• Same type of glass used in the windshields of
  helicopters and high-speed trains
• Chemically strengthened to be 20 times stiffer
  and 30 times harder than plastic
• The glass is ultradurable, scratch resistant
• Recyclable
• Stainless Steel
• Regular stainless steel if formed by fusing
  chromium and nickel into an alloy with the steel
• Then its placed in a superheated salt bath to
  absorb the nitride
• This results in a coating 15 microns thick
• Hardness is increased by a typical Vickers
  Hardness rating of 140

8
Packaging

• Majority of packaging made from post-consumer
  recycled fiberboard and biobased materials

Sales, Distribution and Transportation

• Shipped from manufacturer, Foxconn, from China
• Distributed from China to all countries
  officially selling the iPhone 4
• ATT, Verizon, Best Buy
• Pre-orders weeks ahead
• 1.5 million devices sold on first day

Final Disposition

• PVC-free handset
• PVC-free headphones
• PVC-free USB cable
• Bromine-free printed circuit boards
• Mercury-free LCD display
• Arsenic-free display glass
• Hard to dismantle, thus hard to recycle
