Development of a Bioplastic from Banana Peel

The problems caused by synthetic plastics have motivated the use of other materials. This research consisted taking advantage banana peel and cellulose from pseudostem this plant to obtain a bioplastic. Dry milling was applied extract flour an acid-alkaline treatment for cellulose. elaboration thermoplastic material did with mixture design where fixed amounts shell (5 g), 15% NaOH mL), water (4 varying concentrations plasticizers, which were glycerol sorbitol. In two formulations, added as filler 0,5 g bioplastic obtained characterized according its thickness, vapor permeability (WVP), tension force (TF), break time (bt), biodegradability. type plasticizer content not affect thickness bioplastic, but it WVP, TF, bt. WVP decreases when glycerin is used increases addition best result 1,83 x 10-9 g/Pa.s.m in formulation only glycerol, while values bt, biodegradability 2,4 MPa, 17 seconds, 37,77%, respectively, 75% sorbitol 25% glycerol. Expanding study formulations would allow their replacement plastics.
