The present study was undertaken to investigate the removal of 16 polycyclic aromatic hydrocarbons (PAHs) listed as priority pollutants by the US Environmental Protection Agency (USEPA-PAHs) that are found in coal-contaminated soil during simulated in-vessel composting. Contaminated soil (S) was mixed with green waste (W) in the ratios of 3:1, 1:1, and 1:3 under neutral and acidic soil conditions in laboratory-scale composting reactors. The highest removal efficiency of total 16 USEPA-PAHs (71.88%) was observed in S:W ratio of 1:1 and neutral soil treatment with the removal rate constant of 0.0106 day-1. Results found that the S:W ratio significantly influenced the removal of PAHs during composting but not the initial soil pH. The results of this research suggest that composting is a feasible and appropriate technology to remediate soil contaminated by coal-native PAH.
