Cellulose nanocrystals (CNCs) synthesized from microcrystalline cellulose by acid hydrolysis were added into poly(lactic acid)-poly(hydroxybutyrate) (PLA-PHB) blends to improve the final properties of the multifunctional ...
[EN] Poly(lactic acid) (PLA) is the most used biopolymer for food packaging applications. Several strategies have been made to improve PLA properties for extending its applications in the packaging field. Melt blending ...
[EN] Fully bio-based materials based on thermoplastic starch (TPS) were developed starting from corn starch plasticized with glycerol. The obtained TPS was further blended with five pine resin derivatives: gum rosin (GR), ...

Edible active films based on sodium caseinate (SC) and calcium caseinate (CC) plasticized with glycerol (G) at three different concentrations and carvacrol (CRV) as active agent were prepared by solvent casting. Transparent ...
[EN] Lignocellulosic wood flour particles with three different sizes were used to reinforce
Solanyl® type bioplastic in three compositions (10, 20, and 30 wt.%) and further processed by
melt-extrusion and injection molding ...
In this work poly(lactic acid) PLA, and poly(hydroxybutyrate) PHB, were blended and plasticized with a natural terpene d-limonene (LIM) with the dual objective to increase PLA crystallinity and to obtain flexible films ...
[EN] In this work, the effect of the addition of different amount of nanosized hydroxyapatite (nHA) on the shape memory behavior of blends based on poly (lactic acid) (PLA) and poly (epsilon-caprolactone) (PCL) has been ...
[EN] This research reports the manufacturing and characterization of green composites made from recycled polypropylene obtained from the remnants of polypropylene non-woven fabrics used in the textile industry and further ...
[EN] Spent coffee grounds have been successfully used as an alternative infusion for kombucha fermentation (spent coffee kombucha, SCK). The obtained by-product of this fermentation consists of a kombucha bacterial cellulose ...
