Cover Story: PLA biocomposites with lignocellulosic fibres (LFs) from Posidonia oceanica waste with different degrees of cellulose purification were obtained via melt blending and compression moulding. The LFs were obtained after removing part of the non-cellulosic components using subcritical water extraction at 150 or 170 °C and after bleaching the extracted residues with hydrogen peroxide or sodium chlorite. The LF composition had a noticeable effect on the composites’ optical, mechanical, and barrier properties. All LFs reduced the water vapour barrier capacity while promoting the oxygen barrier of the films. Bleached LFs enhanced the film stiffness and reduced extensibility and resistance to break, whereas non-bleached LFs had a lower impact on the tensile parameters. The fibres obtained at 170 °C and bleached with sodium chlorite exhibited the best performance. View this paper
