Cradle to Cradle is a philosophy that
evaluates products for sustainability and efficiency during each stage of the
lifecycle: design, materials sourcing, manufacturing, consumer usage, and
post-consumer usage. The key element of this philosophy is to design products
that are reused, recycled, or composted, rather than those that end up in a
landfill (the latter being the more common alternative, referred to as “cradle
to grave,” with the landfill being the grave).
