Desarrollo de un envase térmico biodegradable a base de harinas de cascarilla de (Oryza sativa), cáscara de mango (Mangifera indica) y almidón de yuca (Manihot esculenta).

Abstract

Bioplastic is a material similar to plastic made with plants or other biological materials instead of petroleum, it can be made from polylactic acids (PLA) present in plants or from Polylactic acid (PHA) produced from microorganisms. PLA is commonly used in food packaging and PHA in medical devices such as sutures and cardiovascular patches. The objective of this work is to develop a biodegradable thermal packaging (ETB) based on mango peel (CM), rice husk (HCA) and cassava starch (AY) as an alternative to the use of plastic, changing the concentrations of flours, evaluating their effect on physical properties, thermal conductivity coefficient and degradation time. It will be a descriptive investigation; the data will be evaluated with the analysis of variance, defining as independent variables the concentration of CM, HCA and AY with 3 levels of substitution (15 to 30 %) and a control (100 % mass of the bioplastic) methodology based on the authors Avalos and Torres. A completely randomized design with 14 treatments and four replications will be used, giving a total of 56 samples. For the selection of the best formulation, the best results of the mechanical and thermal properties and biodegradability will be considered to verify its compliance with the standards. The Benefit / Cost analysis will demonstrate the viability of the project.
