Abstract
Currently there is a tireless search for sustainable solutions to minimize plastic waste in the environment. In this sense, this work aimed to develop a biodegradable packaging from mesquite pods (Prosopis juliflora), to act as a potential replacement for commercial packaging in the agro-industrial sector. To this end, mesquite pod flour (FV) was obtained to produce containers for plant seedlings. During processing, the flour was mixed with an adhesive solution of wheat starch, glycerol and NPK, molded manually and dried in an oven. The containers were evaluated by X-ray Diffraction (XRD), Fourier Transform Infrared (FTIR), Ultraviolet-Visible Spectrophotometry (UV-Vis), Mechanical Resistance, Contact Angle (AC) and Water Absorption. The packages obtained semi-crystalline behavior, due to the presence of lignocellulosic compounds and the addition of NPK did not influence the chemical interactions between the adhesive solution and the FV. With the increase in the concentration of FV in the containers, the ultraviolet light absorption properties were intensified, but resulted in packages with lower tensile strength and greater water absorption.
