Apple's agenda to be more kind to the planet isn't just about getting Friends of the Earth off its back, it's also about saving bucketloads of cash. The company published its environmental responsibility report for last year that reveals that recovering precious metals from old iPhones is worth plenty of money. The firm pulled 61,357,800 pounds of raw materials out of discarded devices, including 2,204 pounds worth of gold. Cult of Mac consulted the day's metal prices and found that the gold alone was worth $40 million. In addition, the company pulled out 3 million pounds of copper (worth $6.4 million) and 4.5 million pounds of aluminum ($3.2 million).
