Each of the body, the cap, the striker, the spin wheel and the button is a molded plastic part, made out of mostly polycarbonate, which slide, snap, screw or rest in place, without the use of adhesives or fasteners. Also disclosed is a system for recycling a drug injection device having molded plastic parts made from mostly polycarbonates, comprising disassembling the drug injection device, separating the molded plastic parts from all other parts, and reprocessing the molded plastic parts together into recycled resin, which may be through regrinding, melting, and pelletizing.
