It's a great idea! I've seen magnets used in recycling facilities to select cans and other metal objects from the rest of the garbage, so I think this could be easy to implement. The part that i find more difficult is finding a recyclable material that does not affect the process of recycling plastics. Tell us wich one will work when you find it! Good luck!
Hi Lincoln! I love your project it's a great idea! I think it could help to have currency to those developing areas that are too poor or too far from a bank to have real currency. Have you ever calculated the aproximated value of each coin? There are a lot of things interacting in the value: the real value of the material, the savings in recycling, logistics, etc. Good work!
