We sort waste by material, check any plastic we’re not sure about, and turn clean, single-type material into something useful: filament (the plastic thread 3D printers use), sheets from bottle caps, moulded pulp from cardboard. Dead electronics are taken apart for their motors, rails and screws.
The first machine is a small one that turns a drink bottle into filament. The long-term design is the universal recycler: one modular line that sorts by physics — magnets, air, water, static — into clean streams.
