The starch based biopolymers present several drawbacks like poor mechanical properties and very high density. In order to overcome these drawbacks two research lines have been set up: blending thermoplastic starch with biobased reinforcements from agricultural wastes like barley straw and grape wastes, and testing the foamability of these materials with a Microwave-foaming method.engBarley strawBiobased polymerBiodegradable polymersMicrowaveStarch foamsBio-based polymersBiobasedBiodegradable plasticsExpanded polystyreneFoamabilityFood packaging marketsGrape wasteHigh densityStarch-basedThermoplastic starchBiopolymersBlendingMaterials testingMechanical propertiesMicrowavesPlastic productsPolystyrenesStarchStrawTrabalho apresentado em eventoAcesso aberto2-s2.0-84857811241
