This review article aims to identify current research areas in nanocellulose production from various agricultural waste materials. In the arena of sustainable materials, nano-sized cellulosic materials have achieved great curiosity from scientists and researchers. Nanocellulose is embellished with some remarkable properties like biodegradability, renewability, low density, low weight, high strength and high stiffness. Nanocellulose is a versatile material and show pertinence towards variety of applications such as heavy metals, pharmaceuticals, medicines, textiles, barrier, reinforcing polymers etc. This review is an effective tool to introduce numerous agricultural waste materials used for the extraction of different forms of nanocellulose viz. cellulose nanofibres and cellulose nanocrystals. The most common preparation methods of nanocellulose are oxidation, high pressure homogenization, refining, electrospinning, steam explosion, acid hydrolysis, enzymatic hydrolysis etc. This review emphasize upon acid hydrolysis as one of the most prominent approach to synthesize nanocellulose by utilizing agricultural waste. This strategy to materialize nanocellulose provides an outlook for the future perspectives in overcoming the global issues like stubble burning, curbing air pollution etc. in a facile manner.
本文旨在从各种农业废料中确定纳米纤维素生产的当前研究领域。在可持续材料领域，纳米纤维素材料引起了科学家和研究人员的极大兴趣。纳米纤维素具有生物降解性、可再生性、低密度、低重量、高强度和高硬度等一些显著特性。纳米纤维素是一种多功能材料，适用于多种应用，如重金属、制药、医药、纺织品、阻隔、增强聚合物等。本文综述是一种有效的工具，可介绍用于提取不同形式的纳米纤维素（即纤维素纳米纤维和纤维素纳米晶体）的多种农业废料。纳米纤维素的最常见制备方法是氧化、高压均化、精炼、静电纺丝、蒸汽爆破、酸水解、酶水解等。本文综述强调酸水解是利用农业废料合成纳米纤维素的最突出方法之一。这种实现纳米纤维素的策略为未来以简单的方式克服全球问题（如秸秆燃烧、遏制空气污染等）提供了前景。
