Planet-friendlyrefurbished = less e-waste

Every device is graded for cosmetic condition and tested for full function against our TrueGrade 25-point inspection. Buying refurbished keeps a working phone out of landfill — better for your wallet and the planet.

Better for your wallet & the planet

Every refurbished phone is a win for the planet

Choosing refurbished over new keeps a working device out of landfill — and skips the carbon, water and raw materials it takes to build a brand-new one. A small choice with real impact.

Less carbon

Most of a phone's lifetime emissions come from manufacturing. Reuse skips nearly all of it.

Less e-waste

Millions of devices are trashed every year. Every reused phone is one less in a landfill.

Fewer raw materials

No new mining of rare metals, no manufacturing water use — the device already exists.

Circular by design

When a device truly can't be saved, we harvest its working parts and recycle the rest responsibly.

Refurbished is not a compromise. It is the smarter, greener way to buy tech, and every TrueGrade device ships tested, graded and ready for its second life. See how we do it →
