20.500.12556/DiRROS-18389 Weathering effects on cellulose acetate microplastics from discarded cigarette butts Cellulose acetate, commonly used in cigarette filters, poses environmental concerns due to its questionable (bio)degradability and prevalent presence in nature. This study compares the weathering effects on two types of cigarette filters: traditional and newer filters used in heated tobacco devices (HTP). Microplastics were derived from used cigarette parts and then subjected to artificial aging. Analytical techniques (Thermogravimetry-Differential Scanning Calorimetry TG/DSC, Fourier-Transform Infrared Spectroscopic Analysis (FTIR)) and loose bulk density measurements were employed pre- and post-aging cellulose acetate of both types of samples. Despite increasing evidence influencing European Union (EU) directives on tobacco product disposal, there's a lack of systematic analysis on the weathering impact, especially concerning the touted environmental benefits of newer filters. Results indicate decreased particle size in cellulose acetate filters post-aging. Variances were observed in thermal behavior, yet FTIR spectra remained unchanged. cellulose acetate cigarette filters microplastics artificial weathering polymer degradation celulozni acetat cigaretni filtri mikroplastika umetno pospešeno staranje degradacija polimera true false true University of Ljubljana Press Angleški jezik Slovenski jezik © 2024 by the authors.
