Single use water bottles are a prime example of a plastic that is not always recycled leading to environmental concerns. At WPI, students are constantly 3D printing plastic parts for different projects, frequently these parts add to the environmental problems since most prototypes are thrown away to be recycled. There is a need to repurpose this plastic waste which is where this project comes in. This project consists of a recycling system composed of a mechanical shredder, a filament extrusion machine and a filament winder in order to repurpose plastic waste into 3D printing filament. This is a system that has been prototyped at a small scale. It can be applied to larger scale applications.
