In its annual Environmental Responsibility Report for fiscal year 2015 released last Thursday, tech giant Apple has revealed that nearly 90 million pounds of unwanted or broken electronics were processed by the company over the last one year.

According to the details shared by Apple in the report, recyclable materials - including steel, cobalt, aluminum, copper, and silver, among others - comprised approximately two thirds of the 90 million pound scrapheap processed by the company.

Apple also revealed that the worn-out or dumped Mac computers and Apple's mobile devices included almost 2,204 pounds of gold, which was worth approximately $40 million.

Other than recycling $40 million worth of gold from its old and abandoned devices, Apple also -- as per Cult of Mac estimates -- extracted nearly $6.4 million worth of copper from the devices, as well as $3.2 million worth of aluminum, $1.6 million worth of silver, and $40,000 worth of lead, among other reusable materials.

In its latest Environmental Responsibility Report, Apple reiterated its commitment to "conserving precious resources;" and said: "In 2015, we diverted more than 89 million pounds of e-waste from landfills."
