Abstract: Abstract: This study proposes a biotrickling filter-microbial fuel cell (BF-MFC) system as a bioreactor for processing ethyl acetate (EA) waste gas and generating electricity. The EA removal efficiency (RE) and kinetic characteristics of the BF-MFC system were also evaluated. The results revealed that the BF-MFC system in which conductive coke was used as packing materials exhibited a RE of 91.3–99.2% under organic loading (OL) of 34.3–65.1 g/m3/h and an empty bed retention time (EBRT) of 61–115 s; moreover, the average closed-circuit voltage was between 596 ± 14.8 and 538 ± 21.4 mV. When the EBRT of the BF-MFC decreased to 46 s and the OL increased to 85.9 g/m3/h, the maximum elimination capacity (EC) of the system was 69.8 g/m3/h and the maximum closed-circuit voltage reached 504 ± 12.0 mV. The kinetic analysis results revealed that the half-saturation constant (KS) was 0.0066 g/m3 and that the maximum substrate degradation rate per unit volume (rmax) was 0.038 g/m3/s. These results confirm that the proposed BF-MFC can effectively process EA waste gas and convert it into electricity to achieve the goals of removing pollutants while generating power.
