The company’s research concluded that recycled aluminum should come from Apple products rather than recycling facilities because of the high-grade quality required.
Apple has been encouraging customers to return used products for recycling and has melted down iPhone aluminum enclosures to make mini computers used in its factories.
“For tin, we took a different approach,” the company said. “Unlike aluminum, there is an existing market supply of recycled tin that meets our quality standards.” As a result, Apple has been using recycled tin for its iPhone 6s. The ultimate aim is “to one day end our reliance on mining altogether,” the company said, without specifying a date.
Apple did not disclose the amount of recycled products currently used in its products.
