Biocomposite comprises starch-based foam fraction of defined particle size and bio-based binding agent formed as pressed structural component

Biocomposite comprises a starch-based foam fraction of defined particle size and a bio-based binding agent, where the foam fraction and the binder are formed as pressed structural component. Independent claims are also included for: (1) producing the biocomposite, comprising producing the starch foam particles or providing the recycled starch foam particles of defined particle size, mixing the starch foam particles and bio-based binding agent using a mixer, placing the resulting mixture of the starch foam particles and bio-based binding agent into a mold, and pressing and curing the resulting composite material; and (2) producing the starch foam core, comprising introducing a starch suspension formed from cornstarch and water into an extruder, foaming the starch suspension to a starch foam after removing from the extruder, and curing the starch foam. Die Erfindung betrifft einen Bioverbundwerkstoff, bestehend aus einer stärkebasierenden Schaumfraktion definierter Partikelgröße und einem biobasierten Bindemittel, wobei die Schaumfraktion und das Bindemittel als gepresstes Strukturbauteil ausgebildet sind.
