"From Sugar Mills to Sustainable Markets: A Circular Economy Model for Converting Sugarcane Bagasse into Bioplastic Granules and Its Comparative Sustainability Assessment Against Conventional Petrochemical Plastics"

Abstract

The global packaging industry faces increasing pressure to reduce dependence on petroleum-derived plastics due to environmental pollution, health concerns, and regulatory restrictions. This study investigates the feasibility of converting sugarcane bagasse, an abundant agricultural residue, into biodegradable bioplastic granules and evaluates its technical, economic, environmental, and health performance relative to conventional petrochemical plastics. A novel Circular Sustainability Performance Framework (CSPF) is proposed integrating Life Cycle Assessment (LCA), Health Risk Assessment (HRA), Economic Viability Analysis (EVA), and Regulatory Readiness Assessment (RRA). Secondary data from industrial reports, scientific literature, regulatory databases, and case studies from India, Brazil, Mauritius, Europe, and North America were analyzed. Findings indicate that bagasse-based bioplastics reduce lifecycle carbon emissions by 65–80%, eliminate exposure to phthalates and heavy metals, decompose within 60–90 days under industrial composting conditions, and align with emerging global packaging regulations. Although current production costs remain higher than conventional plastics, economies of scale, technological advancements, and regulatory incentives are expected to significantly narrow the cost gap by 2030. The study concludes that sugarcane bagasse bioplastics represent a viable pathway toward circular economy development, rural industrialization, and sustainable packaging transformation in India and other sugar-producing nations.
