(FR) DISPOSITIFS BIODÉGRADABLES ET LEURS PROCÉDÉS DE FABRICATION
Abstract
(EN) A bioplastic blend is disclosed. The bioplastic blend may comprise a polylactic acid polymer and a lignocellulosic biomass. The lignocellulosic biomass may be a particulate and have an average particle size that is less than or equal to 60 micrometers, or less than or equal to 50 micrometers. The lignocellulosic biomass may be a particulate and comprise greater than or equal to 50 percent by weight of the bioplastic blend, or greater than or equal to 60 percent by weight of the bioplastic blend. In addition, the bioplastic blend may comprise a plasticizer.
(FR) L'invention divulgue un mélange bioplastique. Le mélange bioplastique peut comprendre un polymère d'acide polylactique et une biomasse lignocellulosique. La biomasse lignocellulosique peut être une matière particulaire et peut avoir une taille moyenne de particule inférieure ou égale à 60 micromètres, ou inférieure ou égale à 50 micromètres. La biomasse lignocellulosique peut être une matière particulaire et peut comprendre au moins 50 pour cent en poids du mélange bioplastique, ou au moins 60 pour cent en poids du mélange bioplastique. De plus, le mélange bioplastique peut comprendre un plastifiant.
