A novel green manufacturing process for medium and high-density fiberboard (MDF and HDF) production is disclosed, where the green manufacturing process refers to a novel low-emitting manufacture of MDF and HDF in terms of HAP emission. The novel manufacturing process comprises a preconditioning unit operation for raw wood furnish material, where blends comprising two or more woody materials having disparate moisture contents are held in a preconditioning vessel for up to 48 hours under controlled temperature conditions, where the moisture content is homogenized to produce a blend having substantially uniform moisture content. The blend is preconditioned in the novel manufacturing process to facilitate moisture homogenization kinetics, and to uniformly increase the material temperature above the lignin glass transition temperature. Subsequent process steps, such as defibration and fiber drying, require lower temperatures to produce and dry wood fiber, thus lowering HAPs emission.

The invention relates to a method for foaming chipboard with tubes including a board body interspersed by tubes and having an upper and a lower face includes the steps of providing a corresponding chipboard with tubes, defining one or more machining regions on the upper and/or lower face of the chipboard with tubes, machining the machining regions.

In order to provide a method for foaming chipboard with tubes and a chipboard with tubes having foamed tubes that can be used in a simple, flexible, and cost-effective manner while also being highly robust, a foam-forming material is introduced at least in portions of at least one of the above-mentioned tubes in the machining region in order to locally reduce the difference in density between the tubes and the board body. The invention further relates to the use of a device for foaming tubes of a chipboard with tubes.

A filler material is applied to a plurality of wood elements. The plurality of wood elements is bonded into a composite wood product, where the bonding includes delivering ultrasound energy to the plurality of wood elements. The ultrasound energy has a frequency within a frequency range of 10 kHz-20 MHz.

A blended wood interior trim molding assembly (e.g., a blended wood interior door stop assembly) can include a first layer of engineered wood material having a first, generally rectangular cross-sectional thickness, and a second layer of wood material having a second, generally rectangular cross-sectional thickness. The second layer of wood material is joined to the first layer of engineered wood material at a planar interface. Together, the first layer of engineered wood material and the second layer of wood material have a total thickness, with the second, generally rectangular cross-sectional thickness being greater than or equal to at least about fifteen percent (15%) of the total thickness of the first layer of engineered wood material and the second layer of wood material.

The present invention relates to a multi layer particle board comprising at least one core layer and two surface layers, the core layer particles being bonded by a resin binder other than a carbohydrate based binder resin, and the surface layer particles being bonded by a carbohydrate based resin, and to a process for making same.

The present invention relates to a composition for increasing the retention of a biocide in a glueline-treated glued-wood product, a method for increasing the retention of a biocide in a glueline-treated glued-wood product, a glueline-treated glued-wood product, a glue for producing a glueline-treated glued-wood product, and the use of a composition for increasing the retention of a biocide in a glued-wood product.

A process for making an animal litter from a woody biomass starting material is described, with the performance amendments substantially located entirely on the outside surface of the woody biomass particles. The process may include the steps of densifying the biomass starting material, crumbling the densified biomass material; screening the densified biomass material for size; optionally adding a zeolite containing a scent; spray coating the sized, densified biomass particles with a surface adhesion agent; and powder dosing the sized, densified biomass particles and zeolites with a performance amendment comprising equal parts bentonite and guar gum.
