Polyformer recycling machine by Reiten Cheng next to a plastic bottle

Dezeen Agenda newsletter features an open-source recycling machine for plastic bottles

The latest edition of our weekly Dezeen Agenda newsletter features Polyformer, an open-source recycling machine that can be used to turn PET bottles into filament for additive manufacturing. Subscribe to Dezeen Agenda now!

Developed by California-based industrial designer Reiten Cheng, Polyformer was designed to make it easier for independent makers to create products from repurposed waste materials instead of relying on virgin plastic.

The L-shaped gadget can be 3D printed using open-source instructions so that it can be used and adapted by others.
