VOC removal from automotive waste by supercritical CO2 extraction
This study investigated the reduction of volatile organic compounds (VOCs) from waste polypropylene (PP) from automobile bumpers by supercritical carbon dioxide (scCO2) extraction. The scCO2 extraction was performed with varying temperatures, pressures, and times in the range of 313–353 K, 10–25 MPa, and 1–6 h, respectively. At 333 K, 25 MPa, and 6 h, highly efficient removal of xylene, styrene, and total VOCs were observed, with removal percentages of >98 %. Optimal condition for VOC removal using scCO2 based on response surface methodology was determined to be 313 K, 10 MPa, and 2.17 h. No differences in size and color were observed in the scCO2-treated PP pellets. Moreover, VOC removal using scCO2 did not induce noticeable changes in the chemical and thermal properties of the treated PP samples. This result demonstrated that scCO2 extraction is a promising method for the VOC removal from automobile plastic waste.
