Olympic Medals
Love that Canada is using recycling electronic waste in it's medals, here is a quote from the article in Scientific American:
The more than 1,000 medals to be awarded at the Vancouver 2010 Olympic and Paralympic Winter Games, which kick off today, amount to 2.05 kilograms of gold, 1,950 kilograms of silver (Olympic gold medals are about 92.5 per cent silver, plated with six grams of gold) and 903 kilograms of copper. A little more than 1.5 percent of each gold medal was made with metals harvested from cathode ray tube glass, computer parts, circuit boards and other trashed tech. Each copper medal contains just over one percent e-waste, while the silver medals contain only small traces of recycled electronics.
