Zusammenfassung:	Environmental concern about synthetic polymers and nanoparticles bring about development of the green bionanocomposite. Nanocellulose (NC) as safe nanofiller was prepared from beer industrial residues by acid hydrolysis in this study. ATR–FTIR spectrum showed no change in chemical structure of kefiran and NC after mixing. However, mechanical, visual, and WVP properties of kefiran/NC films improved with NC, but thermal properties and water sensitivity of them declined, simultaneously.
