The general inventive concepts relate to engineered wood products. The engineered wood products demonstrate improved properties including acoustic damping, fire resistance, and water absorption relative to similar engineered wood products that comprise only a single source of fibers. In contrast, the inventive engineered wood products include a combination of at least two types of fibers.

A manufacturing process is disclosed which relates to the technical field of the manufacture of wood panels, used in the manufacture of furniture, decorative pieces, floorings, partitions, stairs, doors and other applications in the construction industry, more specifically to a manufacturing process and products resulting from panels featuring structural edges made of pieces of wood and central core in a composition of branch/trunk stumps and resin. The invention presents as innovation, a manufacturing process (1) of decorative surface panels (2), using as raw material in their core and texture, tree branch and trunk stumps (3) originating from pruning or that were ripped off due to the action of the wind or natural causes, which have had resin applied (6) inside the structural base plates (4) of the desired shapes or part of them, consisting of ends or edges (5) made of pieces of wood, preferably reclaimed from the construction industry.

The present invention relates to a process for preparing a wood chip board comprising drying a cut raw material, classifying the dried material into several portions, gluing at least one of said portions with a resin and compressing the chip material under pressure and heat to form a board. The present invention also relates to a wood chip board and its use.

A cellulose-based fire resistant insulation and related method for making the same. The insulation includes a plurality of superstructures that establish voids in the insulation. The insulation may be blown in place while the superstructures maintain the void portion of the insulation. The insulation is made with fiber residuals, either alone or in combination with other cellulosic materials. The method of making the insulation includes the steps of treating the cellulosic materials with a fire retardancy chemical or chemicals and creating bonds between the fibers to form the superstructures.

Easy to use and store. an environmentally friendly binding agent for cellulose-containing materials, without animal products, particularly suitable for use in the production of wood composites. and a composite material product obtained with the use of this binder is disclosed.

A method for producing a biofuel by continuous or discontinuous steam cracking of lignocellulosic biomass, comprises: recording a digital model of the optimal steam cracking parameters as a function of the typology of the plant constituents of the biomass; supplying the steam cracking reactor with heterogeneous biomass; measuring at least once during the treatment the typology of the plant constituents of the biomass; and controlling the adjustment of the steam cracking parameters as a function of the typology of the plant constituents of the measured biomass and of the digital model.

Provided is a sheet manufacturing apparatus that can suppress deposited material from wrapping onto a roller. A sheet manufacturing apparatus according to the invention includes: an air-laying unit that lays material containing fiber and resin; and a humidifying unit that humidifies the deposited material laid by the air-laying unit; the humidifying unit including a first air flow generator that generates air flow passing through the deposited material in a direction intersecting the support surface supporting the deposited material, and supplies droplets or humidified air to the deposited material by the air flow produced by the first air flow generator.

A thermal insulation material is made of a plurality of insulating components. The plurality of insulating components includes a first insulating component made of wood shavings. The plurality of insulating components includes a second insulating component made of cellulose fibers, wherein the cellulose fibers are arranged in voids formed between the wood shavings. The cellulose fibers of the second insulating component are produced from decor paper or sanitary paper.

The process for the production of wood fiberboard includes the step in which refined material from recycled wood fiberboards is wetted, heated and pressurized using steam; the step in which this material is kept under pressure and temperature for a certain amount of time, followed by the step of reducing the pressure of this material by at least 3 bar. After this pressure reduction, the material is transformed into recycled wood fibers, possibly with a fraction of wood fiber clumps and any other impurities. The recycled wood fibers are supplied as feedstock in a production line for producing wood fiberboard.
