Design and Modeling of Shredding Machine for Recycling Plastic Waste

Abstract

Coronavirus disease (COVID-19) pandemic affects plastic waste management all over the world. Plastic wastes from the medical field, such as surgical masks and personal protective equipment are massively dumped and affected human health and environmental. There are several strategies to improve medical plastic waste management, one of them is to do recycling. A plastic shredder is a machine used for cutting plastics into smaller parts called granules or pellets. The focus of this paper is to design a shredding machine used for recycling plastic waste. The outcome of this shredding machine can be used for subsequent plastic processing machines such as extrusion and injection machines. The proposed design is prepared using 3D computer-aided design (CAD) software and uses several sources on the market to make improvements. This paper covers the design, material used, and strength analysis of the machine.
