Abstract
This report covers a project for the Division of Product Development at Lund University to build and further develop a plastic shredder. It was based on open-source blueprints from the Precious Plastic machine series, a nonprofit project by Dave Hakkens to reduce plastic waste. Its purpose is to shred common plastic waste so that the shreds can be remelt to create new products by students in the subsequent machines of the series. The main goals of the project were to build the shredder at minimum cost and to develop an improved version after testing it. It was built using in-house machines at the schools workshop and is powered by a gearmotor build from parts found at a local junkyard. Minor modifications were made of the original designs... (More)

Its purpose is to shred common plastic waste so that the shreds can be remelt to create new products by students in the subsequent machines of the series. The main goals of the project were to build the shredder at minimum cost and to develop an improved version after testing it. It was built using in-house machines at the schools workshop and is powered by a gearmotor build from parts found at a local junkyard. Minor modifications were made of the original designs to improve handling and assembling of the machine. The gearmotor and its electronics were also built on a separate platform to create a modularized unit that is easily detached if desired to be used in other applications.
The shredder worked as intended but caused some difficulties during assembly. The redesign addressed this issue aswell as increased the rate of cutting action by modifying the knives and counterknives. Due to lack of time and restricted funds, an actual version of this redesign was never built and tested. (Less)
