A smoking article (1) comprising a substitute filter for standard cellulose acetate filters with improved biodegradability. The smoking article (1) comprises a smokable tobacco rod (2), which includes tobacco and a wrapper, and a filter (3) having a first end (4) and a second end (5). The filter (3) comprises a first filter segment (11) extending to the first end (4) of the filter (3) and placed at an end of the tobacco rod (2) and a largely homogenous, i.e. non-variable along the longitudinal axis and across cross-sectional areas, second filter segment (12) having a length in the range of from 3 mm to 12 mm extending to the second end (5) of the filter (3). The first filter segment (11) comprises cut or shredded plant material. The second filter segment (12) comprises a cellulose material of white or whitish appearance selected from paper, paper containing an adsorbent, paper containing activated carbon, air-laid cellulose, regenerated cellulose, lyocell and/or viscose as filtering material and has a length in the range of from 3 mm to 12 mm. The filter (3) is bio-degradable according to OECD 201 B. |
