Aprovechamiento del mucílago del moyuyo (Cordia lutea) para la elaboración de láminas de plástico biodegradables

This research work was carried out at the Escuela Superior Politécnica Agropecuaria de Manabí "Manuel Félix López". Its objective was to evaluate the usefulness of moyuyo (Cordia lutea) mucilage for the production of biodegradable plastic sheets and consisted of three phases. The first consisted of diagnosing the physical and chemical properties of moyuyo mucilage, where it was determined that it contains a pH of 5.07, a moisture content of 86.91 %, a viscosity of 3945 cP, 65.77 % solubility, 12000 Pt/Co color, 1.049 g/ml density and a total acidity of 0.30 %. The second phase allowed determining the best concentration of moyuyo mucilage for the elaboration of biodegradable plastic sheets, where 4 treatments were proposed with different doses of 10 ml, 15 ml, 20 ml and 25 ml of mucilage, using four additives such as cassava starch, distilled water, acetic acid, distilled water and acetic acid, distilled water, acetic acid and glycerol, where the most effective treatment was T4, which stood out for being the one that obtained the highest tensile strength (13.50 mPa), the highest resistance to water (filtration) (472.33 ml), the highest elongation (37.80 %) and the highest solubility (50.43 %). Finally, in the third phase, a degradability test was carried out in cultivated agricultural soil, under controlled conditions to obtain its degree of biodegradability for a period of 36 days, where T1 was found to have the highest percentage of degradation with 68.29 %.
