I've been hand-punching these disc beads out of reclaimed materials for years at this point. One of my favorite things is telling you exactly what I made the beads out of: these are plastic fast food cups that I find during my clean-ups. I then pair them with gold-plated beads and gold-filled 50mm hoops to create these simple but statement-making oversized hoop earrings.
 
In many cases, there is no current method of recycling the plastics I use via traditional means. While there is no shortage of plastic fast-food cups where I live, there is nowhere locally that they can be recycled.  All plastics are cleaned and sanitized before use. And if you ever decide that you've had your jewelry long enough, you can send it back to me and I'll recycle it again!
