Bike-Powered Shredder Makes Short Work of 3D Printer Waste

A team in the Netherlands developed a bike-powered shredder to process 3D printer waste, converting human effort into mechanical energy to break down plastic into small pieces. The device includes a gear reduction system, a heavy flywheel, and a sturdy frame to handle the force required for shredding. The project aims to demonstrate the initial steps in recycling plastic and highlight the challenges of large-scale recycling. The shredder serves both an educational purpose and as a practical tool for repurposing waste into usable materials.
