Design of an Electro-Mechanical Shredding Machine for Emerging Technologies and Investment Opportunities in Plastic Recycling Technology
AI summary Read the abstract
Researchers designed a machine that shreds plastic waste (PET, HDPE, PP) at 100 kg per hour, using a 7.5 horsepower electric motor, as a step toward recycling. The paper includes design drawings, material choices and cost estimates, and recommends building and testing a physical prototype to confirm the design works safely and effectively.
Plastic pollution poses a critical challenge globally, necessitating the adoption of sustainable recycling technologies. Among the various processes in plastic recycling, shredding is a key pretreatment operation that reduces waste plastic size for easy handling and further processing. This paper presents the design and analysis of an electro-mechanical plastic shredding machine with a capacity of 100 kg/hr suitable for PET, HDPE and PP plastics. The design integrated an electromechanical drive system powered by a 7.5 HP electric motor for reliable and energy-efficient operation. Detailed CAD models, electrical schematics, and bill of materials for ease of fabrication and replication were included in this design. The study integrates theoretical design calculations, material selection, and economic evaluation, highlighting its relevance for emerging technologies and investment opportunities in the plastic recycling sector. The design focuses on energy efficiency, cost-effectiveness, and adaptability for small to medium-scale recycling industries in developing economies. This researcher therefore recommends immediate prototype development and testing to validate the design assumptions, optimize performance, and test for safety and reliability under real operating conditions.
