    In a context of environmental protection, our aim was to replace petroplastic, which is harmful to the environment, with another polymer of biological origin (plant biomass), which has the same potential for use but is ecologically non-polluting. 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.
