METHOD AND PROCESSING SYSTEM FOR REDUCING VOLATILE ORGANIC COMPOUNDS FROM WOOD CHIPS
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.
Bonding wood or other plant products using ultrasound energy
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.
Casket and Method Of Construction
A casket and method for manufacture of a casket is described, and more particularly, for a casket having walls constructed of fiberboard such as medium density fiberboard (MDF). The walls have outside cladding of MDF that is molded or extruded to provide surface contours such as raised and/or recessed features without having to attach such features as separate trim pieces to the walls. The resulting casket provides aesthetic characteristics and strength for use in funeral ceremonies.
METHOD FOR PRODUCING A BIOFUEL BY STEAM CRACKING
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.
Wood Chip Material and Method of its Production
A wood chip material, especially a fireproof water resistant wood chip material, especially a fireproof water resistant wood chip material to make oriented strand boards which consists of a mixture containing 30 to 43 weight percent of wood chips, 53 to 61.9 weight percent of an aqueous solution of silicate, 2 to 5 weight percent of aluminium hydroxide, 1 to 3 weight percent of water, 0.1 to 1 weight percent of a stabilizer of the aqueous solution of silicate, and a hardener of the aqueous solution of sodium silicate in the concentration of 0.5 to 5 weight percent to the pure aqueous solution of sodium silicate providing always that the density of the aqueous solution of sodium silicate ranges from 1370 to 1400 kg/m.sup.3 and the SiO.sub.2 to NA.sub.2O molar ratio in the aqueous solution of sodium silicate ranges from 3.2 to 3.4. A method of production of a wood chip material, especially method of production of a fireproof water resistant wood chip material, especially method of production of a fireproof water resistant wood chip material to make oriented strand boards according to which, as the first step, the aluminium hydroxide is mixed with water, then wood chips are added into the mixture and everything is stirred thoroughly in such a manner that a wood chip mixture is formed, then the stabilizer of the aqueous solution of sodium silicate is added in the aqueous solution of silicate and after that the hardener of the aqueous solution of sodium silicate is admixed in this solution. Then the solution is stirred for 1 to 10 minutes until a binding solution is formed. Then the wood chip mixture is poured, at continuous stirring, in the binding solution and everything is stirred thoroughly again. Then the resulting mixture is poured in the place of application.
Process for producing smooth strand-based siding or structural panels using secondary pressing
A process for producing a smooth-sided strand-based siding or wood structural panel using a secondary pressing process. The secondary pressing process is performed after the primary process completes pressing and consolidation of the substrate/board. The secondary process applies and cures the overlay after applying a water spray on the hot board immediately out of the primary process press, and before overlay application. The application of the water spray causes the surface of the board to swell and cure. A settling period follows to allow the top surface particles and strands to swell along with absorption and evaporation of the moisture. This is followed by surface sanding to remove the telegraphing and produce a smooth surface, which is then followed by lamination of the overlay(s). The process is completed by post-lamination treatment and coating of the board.

METHOD FOR PRODUCING MATERIAL BOARDS IN A PRODUCTION PLANT, PRODUCTION PLANT, COMPUTER-PROGRAM PRODUCT AND USE OF A COMPUTER-PROGRAM PRODUCT
A method for producing material boards in a production plant in which apparatuses form a material into a mat that is pressed to obtain the material board which has specific quality parameters. The production plant and/or the apparatuses are controlled in an open- or closed-loop manner by a controller, which preferably includes a programmable logic controller, and input parameters are received, processed and/or output by the controller. The input parameters are formed at least from settable product parameters for the material board to be produced, from settable and/or recorded plant parameters of the production plant and/or the apparatuses and/or from recorded material parameters. A quality value of at least one quality parameter of the material board to be produced is determined based on the input parameters by an algorithm based on artificial intelligence. The algorithm is trained or formed by a database which has at least one quality parameter and input parameters correlating with the quality parameter.
