I created the ArcticMicroFactory sub-reddit to begin tracking various examples of applied methods for recycling aluminum, copper wire and plastic using proven designs.
The over-all concept behind the ArcticMicroFactory relates to stuffing a number of tools and hardware for processing plastic, aluminum and copper wiring into a 20 foot shipping container. That project is here.
The intent of this project is to condense several examples for recycling aluminum into a single small scale example designed specifically for processing a large volume of aluminum cans yourself at home.
The project will be borrowing a lot of hardware design principles from the Precious Plastic project.
You can download a number of CAD designs and plans for starting a plastic recycling operation at the Precious Plastic community page.
For the purposes of our design, this project will be borrowing the idea behind the shredder and scaling it down to a small enough size to fit in a 500mm x 290mm x 290mm backyard bulk aluminum processor.
