closed loop system

This diagram depicts how i envisage my systems operation, facilitating a closed loop system I look at the life cycles of retail products in the context of the future scenario proposed.
In the scenario parasitic residential towers have become a part of the future Myer centre, the waste from the towers would go through a crushing process  before entering the nano pit chambers where the nano bots would break the materials into their constituent components to then be sorted and distributed to produce new 3D printed products.
