Aprovechamiento de la cáscara de jengibre para la elaboración de plásticos biodegradables.

Abstract

This research aimed to obtain a biodegradable plastic from the starch obtained from the peel of the ginger variety (Zingiber officinale) for use in the industry in various applications. In the first instance, starch extraction was carried out using the wet method, being the one with the best performance. With the starch reached, its physical and chemical particularization was given according to the INEN-1456 regulation, a suitable product suitable for use in the production of bioplastic. To identify the correct way to use this product in the generation, previous practices were carried out to know the correct values of starch and plasticizer to be used, resulting in 4 bioplastics under different formulations. To diagnose its quality, different tests were carried out. On the other hand, in the solubility assessment, the fourth formulation reached 36.11%, a value that exceeded the rest of the formulations. Regarding permeability, all reflected similar weightings. The degradability evaluation was carried out in 3 scenarios: water, soil, and environment; of which; in the fifth week, a degradation close to 97.41% was obtained in the water; however, it did not exceed 50% in the environment. Furthermore, the findings were positive regarding traction since a high resistance was perceived in each one, and its elongation exceeded 50%. It can be affirmed that, when analyzing the resulting data, it can be deduced that the product is of quality. However, trying them with other substances that optimize their quality is suggested.
