Packaging Materials Based on Polyhydroxyalkanoates and Lignin Derived from grape Pomace

Popis výsledku v původním jazyce

Polyhydroxyalkanoates are biodegradable thermoplastic polymers produced by microorganisms with a large applicability. This work suggests the utilization of grape pomace, which is the waste product of the winery industry as a cheap source of fermentable sugars from grape skins and polyphenolic compounds from grape seeds. It will be shown that various bacteria, producing PHA can grow on sugars derived from grape skins. Next, methods for the isolation of low molecular weight phenolics as well as lignin from grape seeds and bunches will be presented. The hypothesis that neutral isolated lignins without other impurities (e.g. sulfur) and with narrow polydispersity can be used as active filler for polyhydroxyalkanoates to prepare foils for packaging purpose has been proofed. In conclusions, the stabilizing and reinforcing activities of lignins have been proffed. This work was funded through the project SoMoPro (No. 6SA18032). This project has received funding from the European Union´s Horizon 2020 research
