The build includes a large gear reduction, a 15 kg flywheel, and a heavy-duty frame to handle the torque from human pedaling. The shredded plastic is intended to be recycled into usable filament or used in compression molding. The project also serves as an educational demonstration of why large-scale plastic recycling remains a genuinely difficult challenge. ## Full article daily.dev links to this article rather than hosting it.
