Google is committed to deploying and maintaining sustainable data center systems. While there are no industry-wide accepted server retirement standards today, Google's approach has been to find innovative ways to maximize the useful life of servers through dedicated reuse and recycle methods. The program has proved to be both operationally cost-effective and environmentally responsible by extracting incremental value out of retired server hardware. The program is designed to follow a serial reuse and recycle path with a focus on maximizing value without compromising environmental or social responsibility.
