Production and Characterization of Microcrystalline Cellulose Particles From Cellulosic Fiber Wastes

Cellulose, the mostabundant natural polymer globally, is vital for sustainable applications. Thetextile industry's environmental impact, contributing to significant waste andemissions, demands innovative solutions. Utilizing cellulosic waste as a rawmaterial holds promise for eco-friendly recycling. This study focuses onfabricating micro-sized cellulose particles from waste jute yarns andregenerated cellulose (viscose) fibers. The particles exhibit appealingattributes such as strength and surface area. Comprehensive characterizationsinvolving microscopy, spectroscopy, and thermal analyses were performed. Notably,particle morphology and structure varied with the source material andprocessing conditions. The findings present a pathway for cellulose wasteupcycling and offer potential for reinforcing composite materials acrossdiverse industries.
