The present invention relates to a process for producing an aqueous slurry comprising a blend of surface modified calcium carbonate comprising particles (MCC) and precipitated calcium carbonate comprising particles (PCC), an aqueous slurry comprising the blend, as well as the blend obtainable by drying the aqueous slurry and their uses in paper, paper coating, tissue paper, digital photo paper, paints, coatings, adhesives, plastics, waste water treating or waste water treating agents.

The present invention relates to a method of producing precipitated calcium carbonate (PCC) where a retention/strength enhancing chemical is added to milk of lime to form a mixture thereof prior to adding the mixture of the retention/strength enhancing chemical and milk of lime to paper making stock in a pipeline leading to a headbox of a paper making machine, whereafter carbon dioxide is introduced to the paper making stock, and the carbonation reaction between milk of lime and carbon dioxide is allowed to proceed in the presence of both fibers and the retention/strength enhancing chemical.

A nanocomposite material with antimicrobial properties, based on cellulose packed with a mineral filler (zeolite) exchanged with silver, characterised in that the mineral filler is made up of Y-type zeolites, while silver occurs in a form bound with the zeolite matrix in the form of cations and, optionally, nanoparticles of reduced silver, as well as a method for preparation of such a material and its application for the wrapping of plants, works of art, archives and antique objects, as well as food, pharmaceuticals and animal fodder.

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.

Disclosed are methods, systems, and articles of manufacture for molded fiber beverage containers capable of containing a variety of fluids, including beverage cups for drinkable beverages, such as hot or cold beverages, carbonated beverages, and/or alcohol beverages. In some aspects, a method for producing a physical barrier to liquids for fibers usable in manufacturing of paper-based beverage containers includes dosing a fiber with a stearate or a saturated long chain fatty acid salt; dispersing undissolved stearate or undissolved saturated long chain fatty acid salt to allow for preparation of a homogenous mixture including the dosed fiber; and adding a divalent or trivalent metal salt to precipitate the stearate or the saturated long chain fatty acid salt from the homogenous mixture, wherein the precipitate is on the surface of the fiber and forms a physical barrier to liquids into the fiber.
