Abstract: A method for the production of paper products, such as paper and cardboard, by recycling cellulose-based raw materials containing starch. The method includes the steps of pulping in water cellulose-based raw materials containing starch, particularly recycled paper products, obtaining a pulped mass; adding to the pulped mass of the previous step under agitation a mineral acid in a quantity that is suitable to obtain a pH of the pulped mass not lower than 4, and obtaining a pulped mass treated with acid. The method further includes the step of subjecting the pulped mass treated with acid obtained in the second step, optionally treated with other chemical additives, in succession, to filtration, pressing and drying, and obtaining a paper product. Paper products obtainable by this method are also related.

Abstract: The process for decorating the surface of a substrate comprises the stages of printing a three-dimensional decorative pattern on one surface of a polymer film using resin, placing the decorated surface of the film and at least one surface of the substrate in contact and providing thermal energy thereto, and detaching the film from the substrate onto the surface of which the three-dimensional decorative pattern has been transferred.

Abstract: A method for detecting human or animal blood traces on a surface is described. The method is fundamentally based on the reaction of luminol and includes the preliminary operation of atomizing an inorganic powder suspension, such as titania, silica, alumina, hydroxyapatite, or the like, onto the surface to be investigated, after which a composition of luminol, a peroxidic oxidizing agent and an alkaline agent in an amount providing a pH within the range of 10 to 14, is atomized on the surface. A kit for carrying out the detection method of the invention is also described.
