Abstract

Life cycle assessment (LCA) covering feedstock sourcing, polymer/composite production and recycling is increasingly essential for sustainable polymer development. This seminar presents LCA studies on polymers and composites involving lignocellulosic biomass, organic waste, and green solvents. Lignin and cellulose have been proposed as fillers to reduce the environmental impacts of biodegradable polymers. Food waste has been used as a feedstock in processes to produce biodegradable polymers and carbon materials for supercapacitors. In addition, γ-valerolactone is being applied to perovskite solar cell manufacturing to enhance device performance while reducing carbon emissions. More recently, vitrimer-based CFRP/NCM cathode and waste plastic recycling have been developed to increase recyclability and improve the life-cycle sustainability of polymer manufacturing. This presentation highlights advances in polymer life-cycle studies, guiding the sustainable development of polymers.
