Water pollution from industrialization and urbanizationpresents an escalating global concern, necessitating advanced, sustainable treatment strategies. Nanocellulose, a renewable and biodegradable nanomaterial derived from lignocellulosic biomass, has emerged as a promising candidate for water and wastewater remediation due to its high surface area, tunable surface chemistry, and ability to be functionalized. This chapter provides an overview of nanocellulose types cellulose nanocrystals, cellulose nanofibrils, and bacterial nanocellulose and their synthesis, functionalization, and application in water treatment. The mechanisms of contaminant removal, including adsorption, ion exchange, and filtration, are explored in detail, highlighting nanocellulose’s efficacy in removing heavy metals, dyes, oils, and emerging organic pollutants. Functionalization strategies, such as carboxylation, amination, and nanoparticle embedding, further enhance removal capacities and introduce antimicrobial and photocatalytic functionalities. The chapter discusses the development of nanocellulose-based membranes and composite materials, their regeneration potential, and their environmental impact, including toxicity and biodegradability. While nanocellulose holds immense potential for sustainable water treatment, challenges such as high production costs, scalability, and regulatory assessments must be addressed to enable commercial deployment. © 2026 Elsevier Ltd.
