- Development of a sustainable bioplastics synthesis route from agricultural waste using catalyzed polymerization and valorization of by-products.

Project Abstract

This study presents a comprehensive approach to producing sustainable bioplastics by converting agricultural waste into high-value polymers through a catalyzed polymerization process while valorizing associated by-products. The research integrates feedstock pretreatment, catalytic polymerization, polymer characterization, and lifecycle assessment to develop a scalable route that minimizes environmental impact and maximizes economic feasibility. Agricultural residues such as lignocellulosic biomass are subjected to optimized pretreatment methods to liberate fermentable monomers and functionalizable oligomers. A tailored catalytic system—comprising a heterogeneous catalyst with tunable acidity and metal sites—is employed to facilitate polymerization under mild conditions, enabling control over molecular weight, polydispersity, and polymer architecture. The produced bioplastics are anticipated to exhibit competitive thermo-mechanical properties, enhanced processability, and improved biodegradability relative to conventional petrochemical-derived plastics. In parallel, by-products from pretreatment and polymerization, including lignin fragments, waxes, and catalyst fines, are valorized into value-added products such as aromatic compounds, bioenergy, carbon materials, and chemical intermediates, thereby improving the overall process economics and waste footprint. The methodology encompasses design of experiments to optimize feedstock ratio, catalyst loading, temperature, pressure, and solvent systems, followed by comprehensive characterization using FTIR, NMR, GPC, DSC, TGA, DMA, and mechanical testing to establish structure-property relationships. A life cycle assessment (LCA) and techno-economic analysis (TEA) are conducted to quantify environmental benefits, energy consumption, greenhouse gas emissions, and cost competitiveness against conventional plastics. The research also investigates the scalability of the process through pilot-scale reactions and process simulation, addressing mass and heat transfer limitations, catalyst recyclability, and end-of-life scenarios including compostability and recycling options. Antibacterial and barrier properties are evaluated to determine suitability for packaging applications, with emphasis on permeability to gases, moisture resistance, and mechanical integrity under real-world conditions. The study aims to deliver a robust, reproducible workflow from agricultural waste to high-performance bioplastic products, supported by a techno-economic model that demonstrates viability in a circular economy framework. Expected outcomes include a validated catalytic system capable of producing polymers with tailored properties, a valorization pathway for lignin- and wax-derived by-products, and quantified environmental and economic advantages that position the technology as a sustainable alternative for packaging and durable goods. The research contributes to advancing green chemistry, waste valorization, and materials science by bridging biomass processing, catalysis, polymer science, and sustainability assessment.

Project Overview
