Saving the Planet

Buying a refurbished phone is a smart way to reduce your environmental footprint

With over a billion of new smartphones produced annually—many of which eventually end up in landfills—choosing refurbished helps break the cycle of waste. Every device we restore and resell keeps valuable materials in use longer, cutting down on harmful electronic waste and promoting a more sustainable future.
