An alternative de-icer system consisted of biodegradable starch-modified KMnO4 (MS), and glycerol solution was proposed and testedwith the present study. Experiments were performed with varying KMnO4 (10, 15, 25%) percentages, MS particle (0.06, 0.12, 0.24 g),glycerol (20, 40, 60%) and solution amounts (3, 6, 12 ml). The main idea was to induce a miniscule exothermic reaction betweenglycerol and KMnO4 to enhance the melting of ice via heat release. The experiments were divided into two groups. Initially, the bestconditions to yield the highest temperature increase was statistically determined, and de-icing experiments were conducted based onthe interpretation of these results. Statistical analyses showed that the amount of $KMNO_4$ and MS had merely been responsible formaintaining an effective decrease in melting time. De-icing experiments conducted in the presence of MS particles indicated a decreasein melting time compared to control systems. This result indicated superior performance of the proposed system over traditional glycerolbased de-icers. The higher decrease in melting time was observed in the presence of spent MS particles indicating their repetitive useand economically sound production.
