"Cradle to Cradle Certification provides a company with a means to tangibly, credibly measure achievement in environmentally-intelligent design and helps customers purchase and specify products that are pursuing a broader definition of quality." (MDBC)

Rather than having a system that generates trash the idea behind Cradle to Cradle is to create a closed loop so that products are reused in another form after their "initial lifecycle."
