There are many frameworks used in defining sustainability – one of the first being “Cradle to Grave”. Cradle to Grave is one of the initial models that addressed material conception and disposal. Though a linear framework, cradle to grave set the stage for a discussion on how to minimize “graves” (aka landfills). As the discussion evolved, the idea of developing closed loop systems became a central topic, and the word grave was dropped and replaced with cradle. Cradle to Grave is a system where material flows on a linear path from extraction to use to waste instead of the loop of cradle to cradle. The Cradle to Grave model takes, makes, and wastes.
