Synthesis and Characterization of Hydrogel from Sago Pith Waste Derived Cellulose for Agricultural Application

The large amount of sago pith waste (SPW) produced by the growing sago industry has become an environmental concern. Instead of being disposed of, SPW could be converted to hydrogel and used for water hydration. In this study, the hydrogel was prepared from SPW cellulose fibers via crosslinking with...
