Abstract
The generation of potato waste and the continued use of conventional plastics have driven the search for materials derived from renewable resources. This study aimed to produce and evaluate bioplastic films obtained from a starch-rich dry fraction recovered from potato peels collected from food service establishments. A quantitative, experimental, and applied approach was employed using a Completely Randomized Design (CRD) with three treatments and three replicates per treatment. A total of 12 kg of potato peels were processed, and nine films were produced using 9 g of dry material per experimental unit. Mass, nominal thickness, and breaking load were measured using laboratory instruments, whereas mechanical performance was evaluated through an adapted, non-standardized manual procedure. A total of 0.498 kg of dry material was recovered, corresponding to a yield of 4.15%. Treatment M2 exhibited the greatest nominal thickness (0.350 ± 0.003 mm), whereas M3 achieved the highest nominal breaking stress (0.982 ± 0.007 MPa). Analysis of variance (ANOVA) and Tukey’s post hoc test revealed significant differences among the three treatments (p < 0.001). It was concluded that M3 exhibited the highest mechanical performance under the experimental procedure employed, although these values require confirmation through a standardized testing method.
