Mankind has explored the natural resources of earth without limits, including extraction of raw material for industry. The planet’s capacity to absorb and convert the waste, resulting from modern life, seems to be inexhaustible. Situation has become a matter of great concern with the exponential increase in the population of planet. Consequently, waste production will increase by many folds. To counter this, alternatives such as substitution of conventional plastics for biodegradables are being studied. So, the main focus during the present work was the utilization of solid potato and wheat waste into biodegradable product such as starch, having various applications. For extraction of starch from waste potato and wheat, hydrothermal pretreatment was performed due to its high conversion efficiency and then compared it with the synthetic starch. Furthermore, kinetics of different starch were also carried out indicating that potato starch was the most suitable candidate and it follows the first order kinetics
