Apple is offering free recycling of all its used products and vowing to power all of its stores, offices and data centers with renewable energy to reduce the pollution caused by its devices and online services.

The iPhone and iPad maker is detailing its efforts to cultivate a greener Apple Inc. in an environmental section on the company’s website that debuted yesterday.

The site highlights the ways that the Cupertino, California, company is increasing its reliance on alternative power sources and sending less electronic junk to landfills.

Apple had already been distributing gift cards at some of its 420 worldwide stores in exchange for iPhones and iPods still in good enough condition to be resold. Now, all of the company’s stores will recycle any Apple product at no charge.

Gift cards will not be handed out for recycled products deemed to have little or no resale value.

The offer covers a wide array of electronics that are not supposed to be dumped in landfills because of the toxins in them. In the past seven years alone, Apple has sold more than 1 billion iPhones, iPods, iPads and Mac computers.

The new initiative, timed to coincide with today’s annual celebration of Earth Day, strives to position Apple as an environmental steward amid the technological whirlwind of gadgets and Internet services that have been drawing more electricity from power plants that primarily run on natural gas and coal.
