A method for embossing a sheet of substrate, wherein the embossing is realized by providing means of at least a first embossing roller and a second embossing roller configured to emboss first structures and second structures, thereby embossing the sheet of substrate when this passes in a nip formed by the first and second embossing rollers, whereby the embossed sheet of substrate is configured to be used in a manufacturing of cigarette filters, and is further configured to be entirely biodegradable. The method comprises providing a sheet of substrate. The method further comprises any one of the embossing steps in a list comprising: embossing the sheet of substrate with first structures to form crimping lines; embossing the sheet of substrate with second structures to form chimney structures; embossing the sheet of substrate with a combination of first and second structures to form crimping lines and chimney structures respectively. The crimping lines have a first width at a surface level of the sheet of substrate, and a first height or depth measured from the surface level in a first range of 0.1 mm to 0.5 mm, thereby configured to be deformable when used in the manufacturing process of cigarette filters. the chimney structures comprise segments that have a second width at the surface level of the sheet of substrate, in a second range of 0.5 mm to 5.0 mm, and a second height or depth measured from the surface level in a third range of 0.1 mm to 1.5 mm, thereby configured to remain open when used in the manufacturing process of cigarette filters and influence a pressure drop of air in such cigarette filters.
