TURNING CHIP INDUSTRY WASTE INTO BIOPLASTICS: A GREEN AND SUSTAINABLE TECHNOLOGY

Abstract

This study focuses on producing eco-friendly bioplastics from chips industry waste, mainly banana and potato peels, as a sustainable alternative to petroleum-based plastics. The dried, powdered peels were dissolved in an alkaline solution, blended with glycerol as a plasticizer, and bio-based binders for casting, then oven-dried at 50–70°C. Sodium hydroxide (NaOH) facilitated lignin and cellulose degradation, while sodium alginate and carboxymethyl cellulose (CMC) improved flexibility. The resulting black bioplastic (without bleaching agents) showed resistance towards strong heat, water, and microbial attack. FTIR analysis confirmed proper blending and structure. Banana peels added flexibility, while potato peels enhanced tensile strength. The study supports India’s Mission 2047 by promoting waste valorisation and biodegradable material development.
