Abstract: The method according to the invention for producing a grass fibre-containing liquid packaging board has the following steps, specifically: providing a fibre suspension formed from at least a first and second pulp type, wherein the first pulp type is constituted by grass fibres, and the second pulp type is selected from a group of pulps which comprises primary fibres such as chemical pulp, for example sulphate pulp or sulphite pulp, in each case based on long-fibre wood or short-fibre wood, wood pulp, and synthetic fibres or recycled fibres based on one or more recycled paper classifications, mixing and/or swelling the fibres in the pulp suspension under predefined conditions with respect to material density and temperature, grinding the at least two pulp types together in a pulp suspension to a degree of dewatering between 40° SR and 60° SR, adding starch and/or a sizing agent as an additive in the mass, diluting the pulp suspension and producing a board on a paper machine, surface sizing the board using a

Abstract: The present invention relates to a method for processing grass or hay as paper pulp having the steps of pre-reducing the grass or hay with a bale breaker and/or a shredder to an average fiber length between 500 mm and 10 mm, preferably between 120 mm and 10 mm, removing impurities and foreign or extraneous substances by means of a cyclone; reducing and fibrillating the grass or hay in a fiber mill, fraying the grass or hay; and screening and/or sifting the grass or hay by means of a circulating-air separator and/or a cyclone screener.

Abstract: The present invention relates to a fibrous material composition having a predefined fraction of fresh fibres and/or waste paper with a further fraction of sweet grass, sedge, seagrass and/or algae fibres and adjuvants and water, where the weight fraction of sweet grass, sedge, seagrass and/or algae fibres is greater than 1 and less than 100 wt. % of the total material mass, in each case calculated as oven-dry material fraction. The invention further relates to a method for producing the fibrous material mixture and its use for producing fibrous-material-containing products.

Abstract: A paper product (1), such as a greeting card, comprises two paper surfaces (2,3) glued to one another by means of an adhesive. Between said paper surfaces (2,3) at least one germinable seed-corn is arranged. According to the invention said germinable seed-corn is located in the area of a section (4). Said section (4) is separable from the paper product along a perforation (5).
