EDO is ECO Rule#6

DESIGN PRODUCTS SO IT CAN BE RETURNED TO NATURE

This way of thinking is attracting attention these days, especially since the epoch making book on production design, "Cradle to Cradle". Products should be designed so that it doesn't become or leave "trash". The 20th century was the age of mass consumtion, mass deposal. Consumers felt satisfaction by buying, possessing, and throwin away. However, we cannot survive the next century wasting resource like that. Packaging should be less, of course, but also the product itself should be designed so the material can be reused many times. According to "Cradle to Cradle", natural material such as wood should be returned to the naturlal ecosystem, while artificial material such as plastic and certain metal should be reused repeatedly. And this can be possible only if the producing companies design their products so they can be taken apart and reused.

People were doing this naturally in the Edo period. Kimonos were all natural materials so returned to the ecosystem as ash fertilizer. Metal were precious material, so they were taken apart and used repeatedly. Recycle is good, but not the best. If you know any Cradle-to-cradle, or EDO product around you, please tell us!
