A second life for technology

Refurbishing helps keep products in use longer.

When a NETGEAR product is suitable for refurbishment, we prepare it for a second life. When it can’t be refurbished, we send it to a certified e-waste recycler, where materials such as plastics, metals, electronics, and cables are separated and responsibly recycled.

From refurbishment through end-of-life recycling, we take the product lifecycle seriously.
