• promising candidate for sustainable material development across various industries. This review focuses on the extraction and isolation of cellulose from different types of biomass waste, including agricultural residues, forestry byproducts, and industrial waste. Several conventional and advanced methods

• technologies. Keywords: biomass waste; cellulose; green technology; photocatalysis; sustainable materials; Introduction The utilization of biomass has gained a lot of interest among researchers; biomass materials for extraction of biopolymers originate from plants, wood, and waste such as fruit peels and
