Waste management inspiration

As i develop my nano pits i have looked to the beating heart for inspiration, the wonders of the human heart and how each mechanism contracts to allow the flow of blood through the body supplying vital life to the extremities of the body is what i intend to develop my design upon. Bellow is a short film illustrating how the heart pumps old blood through the lungs, filtering it and supplying fresh clean blood to the rest of the body. 

I intend to transfer these biological systems into the design of my nano pit, i will be further exploring the waste management system which will collect, disassemble, sort and then distribute the broken down constituent parts of the waste to its storage facility until the constituent components are required for the use in 3D printing individual products.
