A plasticization process was applied to starch extracted from peeled tubers and potato peelings of the "Spunta" variety, and the polymer obtained was characterized. The results obtained revealed: an extraction rate of 10.6% and 2% and a plasticization rate of 168% and 86.1% for peeled tubers and peelings respectively. A heterogeneous microscopic appearance was observed in peel-based bioplastics, with a higher calculated opacity. A calculated biodegradation rate for peel-based bioplastics was 1.6 times higher than for tuber-based bioplastics.enMémoire de Master
