ABSTRACT The invention relates to a method for manufacturing a paper or cardboard product and to a product manufactured by the method. According to the invention, a cellulase enzyme is added to the product during manufacturing, said enzyme causing the product to decompose when exposed to moisture. The enzyme can be introduced into the product in connection with surface sizing, pigment coating or calendering, or it can be added in the form of a solution which is separately applied to the product in the dry end region of the paper or cardboard machine. Experiments have shown that a product manufactured as taught by the invention can be provided with a plastic coating without risk of destroying the enzyme. Cardboard produced by the method of the invention can be used in the manufacture of packages for liquids, of packing boxes or disposable containers, the cellulase enzyme serving to promote decomposition of the products after they have been brought as waste to dumping areas.
