Biopolymers obtained from orange waste based on a decision tree

Organic waste is still of great value and its transformation into biodegradable polymers is part of the circular economy strategy. The main objective of this research was to evaluate different variables that were analyzed through a tree decision method in order to obtain a biomaterial developed through the conversion of orange peels into a biopolymer. The analysis and assessment include different particle sizes of the orange peel powder, different starch types, different cooling, and dehydration processes. The variables that resulted in the best biopolymer were as follows: particle size of the orange peel powder: 250 micrometers, potato starch and corn starch in a ratio of 0:100, cooling of the mixture at room temperature, and finally the application of a dehydration process.
