The present invention relates to a process for preparing a bonding resin, wherein lignin is provided in the form of a solution in ammonia and/or an organic base and mixed with one or more crosslinkers and optionally one or more additives. The bonding resin is useful for example in the manufacture of laminates, mineral wool insulation and wood products such as plywood, oriented strandboard (OSB), laminated veneer lumber (LVL), medium density fiberboards (MDF), high density fiberboards (HDF), parquet flooring, curved plywood, veneered particleboards, veneered MDF or particle boards. The bonding resin is also useful for example in composites, molding compounds and foundry applications.

The present invention relates to a process for preparing a bonding resin, wherein lignin is provided in the form of an aqueous solution and mixed with one or more of a crosslinker and optionally one or more additives. The bonding resin is useful for example in the manufacture of laminates, mineral wool insulation and wood products such as plywood, oriented strandboard (OSB), laminated veneer lumber (LVL), medium density fiberboards (MDF), high density fiberboards (HDF), parquet flooring, curved plywood, veneered particleboards, veneered MDF or particle boards.

The invention relates to a process for producing particle/polymer composites using a substrate S comprising shredded textile fabric products and a polymeric binder P, therewith providing a new method of recycling/upcycling textile waste. Furthermore, a process for the manufacturing of a molded article obtained from the textile-based particle/polymer composite and the use thereof are disclosed.

The present invention provides a moldable mixture containing large portion of agricultural fibers and small portion of a binding agent and a flow-promoting filler material. The moldable mixture is substantially free of formaldehyde, with low moisture content and high draw ratio. The present invention also provides methods of manufacturing molded products and related parts, based on the claimed moldable mixture. Molded products (830) and related parts such as runner (810) and plank (820) with light weight, high density and more complex profile are manufactured by the claimed methods including steps of providing required materials for a moldable mixture, mixing the provided materials to form a moldable mixture, shaking the moldable mixture in preparing for compression molding and compression molding the moldable mixture to form molded products and related parts.

The present disclosure provides an engineered wood precursor mixture. The mixture includes a wood substrate(s) and a binder reaction mixture present in a range of from 3 to 25 parts per one hundred (100) parts of the dry weight of the wood substrate. The binder composition includes an aqueous portion. The aqueous portion includes a carbohydrate-containing component, including glucose, fructose, sucrose, or mixture thereof, in a range of from 2 wt % to 85 wt % based on a dry weight of the binder reaction mixture. The aqueous portion further includes 1 wt % to 33 wt % of a base based on a dry weight of the binder reaction mixture, wherein a pH of the aqueous portion is greater than 10. The binder composition further includes a partially non-dissolved polypeptide-containing component, in a range of from 20 wt % to 85 wt % based on the dry weight of the binder reaction mixture.

The present invention concerns the field of binders suitable for wood panel manufacturing. In particular, the invention regards a composition of bio-binder comprising unrefined biological material and a reactive prepolymer. In a further aspect a method for producing bio-based binders is presented. In an even further aspect the present invention describes bio-based formaldehyde-free binders obtainable from the described methods and their uses. The invention further describes methods for gluing articles and products obtainable from the methods of the present invention.

The disclosure relates to a method for reducing volatile organic compounds (VOC) from wood chips for wood fibre production in a processing system, at least comprising the following consecutive steps: a first thermal treatment of the wood chips in a first thermal treatment device, which is designed to receive VOC-containing waste gases; cleaning the wood chips in a washing device; a second thermal treatment of the wood chips in a second thermal treatment device, which is designed to receive and separate VOC-containing waste gases; digesting the wood chips in a digester, which is designed to receive and separate VOC-containing waste gases; and crushing the wood chips in a refiner, which is designed to separate VOC-containing waste gases. This allows for an efficient, and thus energy-optimised or environmentally friendly and therefore also cost-optimised reduction of volatile organic compounds from wood chips.

A flame-retardant, waterproof and formaldehyde-free board is disclosed. The board includes raw material and a coagulant agent. The mass ratio of the raw material to the coagulant agent is 1:1-5. The coagulant includes Agent (A), Agent (B) and magnesium oxide at a mass ratio of 15:2:8-12. In addition, a method of manufacturing the flame-retardant, waterproof and formaldehyde-free board is disclosed.

A formaldehyde free adhesive composition and a plywood obtained from the adhesive composition is provided, and the plywood has a balanced performance, such as high adhesion strength, sufficient pot-life, and good workability.
