An anonymous reader writes: Apple released its latest annual environmental report yesterday with numbers detailing how much the company has been able to recover from old devices. Business Insider notes that Apple was able to recover over 61 million pounds of steel, aluminum, glass, and other materials from its computers and iPhones. This includes a total of 2,204 pounds of gold worth $40 million at current prices ($1,229.80 per troy ounce of gold). Cult of Mac ran the figures quoted by Apple through today's metal prices, and came up with individual figures for copper ($6.4 million), aluminum ($3.2 million), silver ($1.6 million), nickel ($160,426), zinc ($109,503), and lead ($33,999). Last month, Apple unveiled an iPhone recycling robot, named Liam, that salvages old parts.
