La presente investigación tiene como objetivo analizar la biodegradabilidad de los bioplásticos elaborados a partir de cáscaras de Mangifera indica y Musa paradisiaca, para lo cual se dividió la investigación en dos partes: elaboración del bioplástico y ensayo de biodegradabilidad. En la primera etapa se utilizó una metodología basada en la adición de plastificantes como el agua y glicerol, es aquí en donde se elaboraron bioplásticos con distintos volúmenes de glicerol, para obtener características físicas desiguales. En la última etapa, se utilizó humus de lombriz como medio de degradación, el rango de tiempo utilizado para estimar la biodegradabilidad de las láminas fue de 1 a 4 semanas. Finalmente se determinó que el bioplástico elaborado con cáscara de mango tuvo una reducción del 93,06 % en su peso inicial y el bioplástico elaborado con cáscara de plátano un 73,16 % de reducción en su peso inicial al finalizar el estudio. Con base a los diferentes volúmenes en la adición de glicerol para la preparación del bioplástico se determinó que tiene una relación directa con la biodegradabilidad de la lámina ya que, al aumentar la cantidad de glicerol, aumenta la biodegradabilidad de las láminas.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT Bioplastics have been created as an eco-efficient alternative to traditional plastic. They are obtained from natural polymers extracted from cellulose or starch, and are 100 % biodegradable. The aim of this research is to analyse the biodegradability of bioplastics made from Mangifera indica and Musa paradisiaca peels for which the research was divided into two parts: preparation of the bioplastic and biodegradability test. In the first stage, a methodology based on the addition of plasticizers such as water and glycerol were used. It is here where bioplastics were elaborated with different volumes of glycerol, to obtain unequal physical characteristics. In the last stage, worm humus was used as a degradation medium, the time range used to estimate the biodegradability of the sheets was 1 to 4 weeks. Finally, it was determined that the bioplastic made from mango peel had a reduction of 93.06 % in its initial weight and the bioplastic made from banana peel had a 73.16 % reduction in its initial weight at the end of the study. Based on the different volumes in the addition of glycerol for the preparation of the bioplastic, it was determined that it has a direct relationship with the biodegradability of the film, since the greater the amount of glycerol, this will increase the biodegradability of the films.]]></p></abstract>
