\textbf{Abstract}
\begin{abstract}
\normalsize{
In the world, consumption per capita of potatoes was 34,\mbox{9\,kg} and bananas was 82 million of metric tons (To 2011 according to Food and Agriculture Organisation of the United Nations, FAO). Additionally, FAO estimates that up to a third of the food is wasted. In Colombia that proportion of wasted food is kept based on the data published in 2016 for the DNP (Planning National Department, from its acronyms in Spanish). The percentage of wasted food is up to \mbox{34\,\%} and from this percentage, around \mbox{80\,\%} belongs to fruits, vegetables and tuber. For banana and potato wastes, their peels are processed in order to make animal food with the condition that those wastes must have not started the decomposition process. One alternative to take advantage of those wastes is to obtain a bioplastic based on starch from banana and potato shells. These products are \mbox{100\,\%} biodegradables and researchers have been studying them for different applications, helping in the reduction of organic wastes and ordinary plastic wastes. Without petroleum affecting the prices of bioplastics, bioplastics market has a growing tendency and it is seen that it can keep this tendency in the medium term up to \mbox{350\,\%} (According to the European Bioplastic Conference in Berlin, 2015).



In this work, it will be shown the results for elasticity module and percent elongation for bioplastics obtained from a mixture of starch of bananas and potatoes with glycerol as plasticizer. The experimental variables were the plasticizer percentage and the mixture between banana starch and potato starch. The results show that the bioplastics obtained can be used in different applications such as plastic bags or sorbets, verifying their admissible degradation percentages for each one of these applications. The results also show that they agree with the data found in the literature due to the fact that mixtures with a major amount of potato starch had the best mechanical properties because of the potato starch characteristics.
