REVIEW ON : AGRICULTURAL WASTE BASED HYDROGELS

Abstract

The majority of farm wastes are high in cellulose, hemicellulose and lignin. This are basically biodegradable ,economical and completely environment friendly. There is vast mount of agricultural waste generated everyday . Superabsorbent hydrogels can be made by extracting nanocellulose using chemical or mechanical methods. When used to agricultural fields as soil amendments, superabsorbent hydrogels serve as reservoirs for water and nutrients. This article explores the potential effects of using superabsorbent hydrogels made from agricultural waste and covers current developments in this field. It also looks for its future prospects like uses in agricultural realm and human health. A comparison is made between the advantages and disadvantages of various existing methods and technologies for hydrogel production and nanocellulose extraction. It is discovered that while physical procedures are more expensive and complex, they are environmentally benign, chemical approaches are often more cost-effective but may endanger ecosystems. Given that these new superabsorbent hydrogels have the ability to decrease irrigation, the economic feasibility of applying them as soil amendments is also covered.
