Abstract (en)
[origin: WO2021110540A1] There is provided an aerosol-generating article (10; 100; 310) for producing an inhalable aerosol upon heating, the aerosol-generating article comprising: a rod of aerosol-generating substrate (12; 114; 312); a filter segment (18; 122; 314) formed of fibrous filtration material, the filter segment arranged in longitudinal alignment with the rod (12; 114; 312); wherein the filter segment (18; 122; 314) comprises at least about 85 percent by weight based on the total weight of fibrous filtration material of a polyhydroxyalkanoate (PHA) polymer or copolymer.
