The present invention provides a process for producing paper or board, comprising slushing a stock of dried fibres in a slushing system comprising a pulper, and/or feeding a stock of never-dried fibres in a fiber line of an integrated paper mill; deflaking and/or refining the stock in a deflaker and/or a refiner, optionally diluting the deflaked and/or refined stock, directing the deflaked and/or refined stock to a headbox, forming a web, and drying the web, wherein a polymeric paper making additive is added to one or more of the stocks of dried fibres and never-dried fibres before deflaking and/or refining of the stock. The present invention further provides paper and board with improved properties.

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.

A process for producing a non-woven grass fibre product comprises providing a grass fibre biomass obtained by aerobic fermentation of a meadow grass slurry and removal of digestible elements released during aerobic fermentation, mixing and shaping the grass fibre biomass to form a non- woven grass fibre mat, and binding and drying the mat to form the non-woven grass fibre product. The process includes a step of addition of non-fermented grass to the grass fibre biomass prior to the mixing and shaping step in which the mixture of grass and grass fibre biomass contains 15-50% by weight of grass. The use of a non-woven grass fibre product of the invention as thermal and acoustic insulation material for a building or a vehicle, as a packaging material for industrial products such as engines, industrial machines, and parts thereof, and as a filler for a mattress, is also described.

Methods and apparatus for vacuum forming and subsequently applying topical coatings fiber-based food containers. The slurry includes one or more of an embedded moisture barrier, vapor barrier, and oil barrier, and the topical coating comprises one or more of a vapor barrier, a moisture barrier, an oil barrier, and an oxygen barrier. For food containers having deep sidewalls, a spray coating system includes a first nozzle for applying a full cone spray pattern to the bottom surface of the container, and a second nozzle for applying a hollow cone spray pattern to the inside surfaces of the side walls.
