Recycled PLA key chains
We use the leftover material generated in the printing laboratory.We are studying the feasibility of creating key rings with recycled PLA without having a high environmental impact.
Every month, about 10 Kg of PLA (polylactic acid) material is used in the laboratory and due to printing errors, a considerable amount is wasted.

- We select material that can be easily converted into pellets and grind it with a blender at low speed.
- We fill silicone molds with pellets and melt them at 392ºF. At the end, we eliminate plastic bangs, polish and pierce the piece.
