Development of a green synthesis pathway for biobased polymers using biomass-derived monomers and catalysis optimization

Project Abstract

The project presents a comprehensive investigation into a green synthesis pathway for biobased polymers by leveraging biomass-derived monomers and optimizing catalytic processes to achieve sustainable, high-performance materials. The study integrates feedstock valorization, catalytic design, and process engineering to address environmental and economic challenges associated with conventional petrochemical routes. We begin by mapping biomass streams (cellulose, lignin, and polysaccharide-derived platform chemicals) to versatile monomer precursors through green pretreatment and selective catalytic transformations that minimize energy input, solvent use, and waste generation. A key objective is to establish a modular synthesis framework that can be adapted to produce a range of biopolymers, including polyesters, polycarbonates, and polyurethanes, with tunable properties for applications in packaging, textiles, and automotive components. Catalysis optimization is central to enhancing reaction efficiency, selectivity, and scalability. We explore both heterogeneous and homogeneous catalysts, emphasizing earth-abundant metals and recyclable catalyst systems to reduce environmental impact. Reaction networks are examined through kinetic modeling and design of experiments to identify optimal conditions (temperature, pressure, solvent systems, and catalyst loading) that maximize monomer yield while suppressing unwanted side reactions. Green metrics such as atom economy, E-factor, and life cycle assessment (LCA) are incorporated to quantify improvements over traditional routes. We also investigate solventless or solvent-minimized processes and the use of bio-based solvents to further reduce ecological footprints. The materials characterization phase assesses molecular weight distribution, crystallinity, thermal stability, mechanical properties, and biodegradability of the resulting polymers. The study evaluates process sustainability by analyzing energy consumption, water usage, waste streams, and end-of-life scenarios, including recycling potential and compostability. A pilot-scale demonstration is conducted to validate laboratory findings, with emphasis on process robustness, catalyst recyclability, and polymer quality consistency. Life cycle considerations extend to feedstock supply security, regional availability of biomass, and economic feasibility under current and projected market conditions. Cross-disciplinary collaboration among chemists, chemical engineers, and environmental scientists ensures that the synthesis pathway aligns with regulatory frameworks and consumer safety standards. The research also explores integration with existing biorefinery infrastructures, enabling cascading use of biomass to maximize value recovery. Expected outcomes include a library of green, high-performance biopolymers derived from renewable resources, a set of catalytic protocols offering high selectivity and turnover numbers, and a scalable process design that demonstrates economic viability and reduced environmental impact. The study aims to contribute actionable guidelines and quantitative benchmarks for the advancement of sustainable biopolymers, promoting circular economy concepts and reducing dependence on fossil-based polymers.
