Webb8 aug. 2024 · Starch, a biodegradable agro biopolymer, has certain properties like biodegradation, renewability, low cost. However in native form it cannot be used as adsorbent because of some unwanted properties like retrogradation, rupturing of granules, and weak adsorption functionalities. WebbThermoplastic starch (TPS) is one promising candidate due to wide availability from various renewable sources, low cost and biodegradability.
