Hydrogels are hydrophilic networks of crosslinked synthetic polymers or grafted natural polymers. The latter type involves grafting of a monomer onto a natural polymer using initiator and crosslinker. The present paper comprises of hydrogel manufacturing processes for starch grafted acrylamide (St‐ g ‐Am) using three different grafting techniques (conventional, microwave (MW), and ultraviolet (UV) irradiation). The prepared hydrogel has been characterized using XRD, FTIR, TGA, and SEM. Grafting indicators are compared on the basis of reported typical international and national studies. Moreover, economics and environmental aspects are addressed using the investigated manufacturing procedures. Recommendations for clean technology applications pertinent to hydrogel manufacture are included.
