The present invention discloses a composition that may be extruded or injection moulded, comprising a chemically modified hardwood lignin and a polyester. The chemically modified hardwood lignin constitutes 10 to 50 weight-% of the total weight of the composition.

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).

The present invention provides a chitosan-based composition that can be converted into a self-supporting casted object having good tensile and compressive strength that can also biodegrade at the end of its lifecycle. The composition comprises entirely bio-based or bio-sourced reagents that can be converted to the final product via a polymerization process that does not require the addition of inorganic catalysts, synthetic materials, or otherwise hazardous chemicals to strengthen or modify its water resistance.

The present invention includes methods of making a nanocellulosic composition comprising one or more nanocellulosic components, wherein the one or more nanocellulosic components comprise a micron-scale cellulose or cellulose nanofibrils (CNF), the method comprising the steps of: creating a nanocellulosic slurry by combining the one or more of nanocellulosic components with a liquid component; and exposing the nanocellulosic slurry to a drying condition, wherein the drying condition comprises microwave radiation, thereby creating a nanocellulosic composition. The present invention also includes compositions comprising cellulose (nanocellulosic compositions), wherein the nanocellulosic compositions have an internal void space of about 5% to about 95% by volume.

A composition suitable for making edible films or coatings, the composition comprising a conjugate of bio fiber gum and whey protein isolate and at least one food grade antimicrobial.

A microfibrillated cellulose-loaded foam is indicated, comprising microfibrillated cellulose, at least one thickening agent and/or at least one adhesive biopolymer. Furthermore, a method for producing such a microfibrillated cellulose-loaded foam and a use of such a foam are provided.

A wood polymer composite additive includes at least one maleic anhydride grafted polymer coupling agent, a second coupling agent that is at least one of a silane and siloxane, at least one peroxide crosslinking agent; and an amine compound. A wood polymer composite includes the additive, a thermoplastic polymer and cellulosic material. A wood polymer composite article is formed by extruding the composite material.

The present invention relates to a process for preparing a modified wood product wherein the wood is treated with low-molecular weight resin based on lignin degradation products. The present invention also relates to a modified wood product produced using said process.

A process for the production of particle board, MDF board or HDF board includes the step of recycling particle board material, MDF and/or HDF board material in which recycled chips and/or recycled wood fibers are produced. The process includes the step in which the particle board material, the MDF and/or HDF board material is wetted, heated and pressurized, such that this material is kept under pressure and at an elevated temperature for a certain time. The process involves the step of supplying the recycled chips and/or the recycled wood fibers as base material in a production process of particle board, MDF board or HDF board.

The disclosure is directed to methods of manufacturing protective packaging materials, as well as the protective packaging materials produced using the disclosed methods. These packaging materials can be biodegradable, compostable, and/or recyclable.
