This winter’s Olympic medals contain recycled material from junked electronic equipment like circuit boards and cathode ray tubes that would otherwise occupy a dump. “When Olympic champions are crowned at this year’s winter games in Vancouver, these elite athletes will be taking home more than just gold, silver or bronze medals—they will be playing a role in Canada’s efforts to reduce electronic waste. That’s because each medal was made with a tiny bit of the more than 140,000 tons of e-waste that otherwise would have been sent to Canadian landfills. 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.”
Most electric car charging is done at night. A grid powered mostly by renewable energy might not be able to meet demand, but there is a solution.
