Development and characterization of gelatin-based biodegradable films incorporated with pistachio shell hemicellulose

This study aimed to incorporate pistachio shell hemicellulose into a film of gelatin and glycerol for the production of biodegradable films. The gelatin and glycerol are chosen because of their functional properties, which make it extensively used in food industry. The film composition was defined after a statistical optimization by central composite face-centered design and […]

Effect of thermal annealing and filler ball-milling on the properties of highly filled polylactic acid/pecan (Carya illinoinensis) nutshell biocomposites.

Biodegradable polymer composites reinforced with agri-food lignocellulosic biowaste represent cost-effective and sustainable materials potentially able to replace traditional composites for structural, household, and packaging applications. Herein, the preparation of polylactic acid (PLA)/pecan nutshell (PNS) biocomposites at high filler loading (50 wt.%) is reported. Moreover, the effect of two environmentally friendly physical treatments, namely ball-milling of […]

Studies of Resistance of PP/Natural Filler Polymer Composites to Decomposition Caused by Fungi

The article discusses the grain morphology of the natural filler from hazelnut and walnut shell flour. It was observed that the geometry of both meals is similar to each other and resembles uneven balls in shape. The heterogeneity and well-developed outer surface of the flour grains allow for filling the voids with the polymer matrix. […]
