SAN FRANCISCO - 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 Monday. The site highlights the ways that the Cupertino, Calif., 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 won't be handed out for recycled products deemed to have little or no resale value.
