Apple's 2017 Environmental Responsibility Report, covering fiscal year 2016, states that the company will establish a “closed-loop supply chain” and stop mining the earth altogether in order to make its products from 100 percent renewable or recycled materials, including aluminum, copper, tin and tungsten.
An industry-changing objective, indeed, but Apple has yet to completely figure out how to do it. “One day we’d like to be able to build new products with just recycled materials, including your old products,” said the Cupertino firm.
