It's become a habit of mine to collect/salvage interesting bike parts. This is probably something that I picked up in university. Our student-run bike collective had a deal with a local bike shop; they let us climb in their dumpster and take home any bike parts that we wanted. As a business, it was their job to put new parts on bikes at their customer's request. Sometimes perfectly good parts would get thrown away simply because shops can't sell used stuff. Thankfully lots of bike collectives have a similar deal with a local shop. Many bike shops recycle their rubber and metal already. Some even send away their old bike tubes to organizations like Green Guru or Alchemy Goods. (Encourage your local bike shop to recycle their parts if they aren't!)

I've got my own use for broken and discarded bike parts. 

Use 1: I collect parts for class demos and tactile tools. (I'll write about my teaching philosophy and whyI think people need tactile tools to fiddle with to help lessons sink in in another post.)
Use 2: Jewelry and bike art! That's what this is all about.
