An active moisture control material comprising a fiber based material and at least one active additive, wherein said active additive is adapted to control moisture transfer in the active moisture control material, and wherein said moisture control material is produced in a paper or board making process, wherein the active additive is incorporated into said active moisture control material.

The present invention relates to the use of an activated carrot fiber for preparing products in the food or non-food area. The invention also relates to products containing the activated carrot fiber.

The invention provides a method of producing a filler comprising calcium carbonate (PCC), preferably to be used in paper or paper board production or in fibre based composites. The method of the invention comprises the steps of; —providing fly ash generated in paper or paper board production; —fractionating said fly ash in at least one step, whereby a coarser fraction is separated from a finer fraction; —forming a suspension of said coarser fraction; —adding carbon dioxide to said suspension to form precipitated calcium carbonate. The method of the invention avoids problems with high amounts of arsenic and heavy metals in the production of filler comprising PCC, when using ash generated in paper or paper board production as a raw material. It has been shown that harmful elements, such as arsenic and heavy metals, are primarily accumulated in the finer fractions of the fly ash. Thus, by using the coarser fraction in the step of carbonation, the amount of arsenic and heavy metals in the final product is reduced.

A board including a plurality of layers having a different composition. At least one of the layers is based on MgO and MgChloride and/or at least one of said layers is based on MgO and MgSulphate. Methods for manufacturing such boards, and methods for manufacturing coated panels include such board.

A computer-implemented method for estimating at least one quality parameter of paperboard produced in a paperboard production subprocess of a paperboard processing pipeline by a data-driven module having a preprocessing module and a machine-learning module. Sensor data is acquired along the processing pipeline. Features are extracted from the sensor data by the preprocessing module. The machine-learning module is trained to reproduce target quality values from historical features. After training, the machine-learning module processes real-time features and estimates at least one quality parameter. A system implements the computer-implemented method and to a paperboard production machine includes such a system.
