Tech giant Apple's recycling efforts are paying off and paying off well. In 2015, the company minted one kg worth of gold from its own electronic devices worth $40 million. Translation: 2,66,36,18,000 in Indian rupees! And along came huge chunks of silver (3,000 kgs), copper (13,39,622 kgs), and zinc (1,04,78,437 kgs) from iPhones, iPads, and Macs.

The company, however, won't be taking the fortune to a bank. Instead, it plans to reuse the materials for its new products in a bid to prevent mining of resources. And of course, there will be financial gains to be reaped from the effort as well as Apple will no longer have to procure gold for its iPhone.

Also, according to New York Gold Spot Price, one kg of top quality gold is currently priced at £28,000.

That's Rs. 26,43,233. Per kg. Whoa!

What's even better is that the task of recovering the material has been assigned to Liam - Apple's recently invented robot that was unveiled at the company's spring event.

According to their report,

"Existing recycling techniques, like shredding, only recover a few kinds of materials and often diminish their quality. So we invented Liam, a line of robots designed to disassemble 1.2 million phones a year, sorting all their high-quality components and reducing the need to mine more resources from the earth."
