A multicolor wood-plastic profile is made of a color master batch and a wood-plastic base material. The ratio λ of the tensile elastic modulus (Et) of said color master batch to that of said base material is 0.26-1.47. A manufacturing method for the multicolor wood-plastic profile includes mixing and melt extruding the color master batch and the base material. A wood-plastic board, including the multicolor wood-plastic profile. The outer surface and the interior of the multicolor wood-plastic profile have two or more colors, presenting a mixed gradual texture similar to natural wood.

A hybrid polymer-matrix composite is described, containing between 10.0% and 45.0% by weight of cellulosic fiber up to 3.0 mm long and with a maximum moisture content of 5.0%; between 5.0% and 40.0% by weight of synthetic fiber up to 4.0 mm long and compatibilizing additives, said constituents being homogenized directly in the twin-screw extruder, with each reinforcing fiber entering via a specific feeder, to be adjusted to the temperature and shearing applied to the reinforcing fibers, guaranteeing the correct dispersion of the fiber for encapsulation by the polymer matrix, optimizing interface interactions and perfect homogenization.

The invention relates to the technical field of composites, in particular to a high-toughness and high-strength wood-plastic composite and a preparation method thereof. The wood-plastic composite is prepared from the following preparation raw materials in parts by mass: 30-50 parts of wood flour, 11-20 parts of high molecular weight polyethylene, 30-52 parts of polypropylene and 2-10 parts of an interface modifier. Polypropylene is used as a main component of a plastic matrix; high molecular weight polyethylene is used as a secondary component of the plastic matrix and has a toughening effect; wood flour is used as a filler to improve the strength of the wood-plastic composite; the interface modifier can improve the interface bonding between the wood flour and the plastic matrix, and all components have a synergistic effect, so that the obtained wood-plastic composite has high toughness and high strength.

A process for recycling lignocellulosic fibers from a fiberboard (100) comprising compressed lignocellulosic fibers bonded together by a binding agent. The process comprises the steps of: —disintegrating (101) the fiberboard (100) to provide fiberboard pieces (110); —steaming (111) the fiberboard pieces (110) to decompress and release the lignocellulosic fibers by hydrating them, as well as hydrolyzing the binding agent; —releasing the overpressure; —removing excess water vapor to provide portions (120) comprising released lignocellulosic fibers; and—separating (121) the lignocellulosic fibers in the portions (120) comprising released lignocellulosic fibers to provide recycled lignocellulosic fibers (130).

Biodegradable drinking straws from date palm leaves as a substitute for plastic straws. The straws are made by washing the palm tree leaves with a solution of ascorbic acid, 99% ethanol and water, cleaning the palm tree leaves with abrasive sheets, soaking the palm tree leaves, drying the palm tree leaves, heating the palm tree leaves to a temperature selected from a range of 60° C. to 140° C., rolling the palm tree leaves, binding the rolled palm tree leaves using biodegradable food grade adhesive, drying the rolled palm tree leaves.
