Abstract: A method for recycling and reusing corrugated paper comprising the steps of: pulverizing the waste corrugated paper into a plurality of scraps; adding viscose to mix with the scraps; agitating viscose and the scraps so that a surface of each scrap is stuck with a thin layer of viscose; filling the scraps with viscose into a model; compressing the scraps for solidifying the scraps so as to form a shaped product; and drying the shaped product. The size of the corrugated paper is less than 10 cm. The viscose is water-solvable viscose. The compressing pressure is larger than 15 tons. In agitating step, recycling short fiber for waste paper can be added.

Abstract: A method of treating solid containing material derived from effluent or sludge from a plant for de-inking paper, the material containing calcium in the form of one or more insoluble calcium compounds, the method including the steps of treating the material with an acid to cause dissolution of the calcium thereby forming a calcium ion-containing solution in which insoluble solids are suspended, separating the solution from the insoluble solids and incinerating the separated solids. The solution containing calcium ions may be treated by adding one or more reagents to form a calcium compound precipitate, eg calcium carbonate. The particulate solids produced following the incineration step and following the precipitate formation may be employed as pigments or fillers in paper making or paper coating.

Abstract: This invention relates to an environmentally friendly insulating material, or more specifically an insulating mat for insulating buildings, houses etc. and a method for the manufacture thereof. The mat is non-allergenic and almost 100% recyclable, and is characterized in that it consists of fabric remnants which are shredded into shoddy, mixed with a fibrous polyester with a low melting point and flax fibres to form a homogeneous mass, which is then moulded into the desired shape and then heat-treated until the polyester fibres melt, bonding the fabric and flax fibres together.

Abstract: A pulper for producing paper pulp from waste paper containing undesired scrap particles includes a container (1) forming a chamber (4) defined by a bottom wall (5) and a cylindrical circumferential wall (6). A paper tearing member (7) is arranged in the chamber closed to the bottom wall and is rotatable in a horizontal direction of rotation about the centre axis of the cylindrical wall. The bottom wall and the circumferential wall forms a substantially circular peripheral reject chute (11) situated under the paper tearing member for collecting reject including undesired scrap particles. The reject chute extends helically in the direction of rotation of the paper tearing member from an upper end (12) of the reject chute downwardly to a lower end (13) of the reject chute. The circumferential wall (6) has a substantially cylindrical shape and extends vertically to the reject chute (11). A discharge element (2) is adapted to discharge reject in batches from the reject chute.

Abstract: A method of processing papermaking fiber includes characterizing the initial color of the pulp and the color of the pulp after treatment with a phloroglucinol stain. The color response of the pulp to the stain has been found to be a better indicator of processing needs for secondary pulps in particular and in any event is selective for untreated groundwood as opposed to conventional groundwood identification methods. The color difference is used to target a suitable product for the pulp, to aid in bleaching/deinking strategy or to enable optimization of fiber blending for particular products. In a preferred embodiment the process includes determining changes in CIE L*, a*, b* and brightness values before and after staining of the pulp.

Abstract: A product and process of making an absorbent paper article such as paper products, towels, napkins and the like is disclosed. In the invention, one may supply a single furnish, or slurry, of cellulose fibers. Then, it is possible to separate or fractionate the slurry into at least two portions based upon fiber length in the slurry. Fines are employed in the process of manufacturing the products, and fines are specifically incorporated into an inner layer of the final paper products. Fines, short fibers, and/or fibrils are used in the process so they may contribute in a positive manner to the final paper product, rather than acting in a negative manner as a chemical nullspongenull or waste material. This use of fines in the inner layers of the product reduces the manufacturing cost and waste produced in the process. A soft paper product with good strength characteristics results from the process.
