AB  - The textile industry is a major source of environmental pollution due to the discharge of highly colored and chemically complex wastewater containing toxic, mutagenic, and carcinogenic compounds that are often resistant to conventional treatment. Although conventional chemical coagulants and flocculants such as alum and synthetic polymers are effective, their application raises concerns about excessive sludge generation, residual toxicity, and long-term environmental impacts. This short review critically evaluates the potential of cassava pulp (onggok) starch modified by graft copolymerization with polyacrylamide (PAM) as a bioflocculant for textile wastewater treatment. The review synthesizes current knowledge on textile wastewater characteristics, coagulation-flocculation principles, and the development of starch-based bioflocculants, with particular emphasis on cassava-derived starch and starch-g-PAM systems. Special attention is given to the underlying flocculation mechanisms, including charge neutralization and polymer bridging, as well as to reported performance in turbidity, color, and chemical oxygen demand removal. Furthermore, the environmental and economic advantages of valorizing cassava pulp waste into high-value bioflocculants are discussed in relation to sustainable wastewater management and relevant Sustainable Development Goals (SDGs). Overall, this review provides a focused scientific framework and identifies key research directions to advance graft-modified cassava pulp starch as a low-cost and environmentally friendly alternative to conventional flocculants for textile wastewater treatment.
