Abstract:
The attenuation potential of methane (CH(4)) and of selected volatile organic compounds (VOCs) was compared in four types of compost materials using dynamic flow column experiments over a period of 255 d. Garden waste compost mixed with wood chips showed the highest steady-state CH(4) oxidation rate (161 g m(-2) d(-1)), followed by a commercial compost product Supermuld (110 g m(-2) d(-1)). In the column containing the highest fraction of compost (compost/sand mixed in 1:1), CH(4) oxidation declined significantly during the period of operation, probably due to clogging by formation of exopolymeric substances. After 40 d of operation, CH(4) production was observed. All the VOCs tested were degraded. CFC-11 (CCl(3)F) and HCFC-21 (CCl(2)FH) were anaerobically degraded by reductive dechlorination, generating HCFC-31 (CClFH(2)) and HFC-41 (CFH(3)), which were both aerobically degraded in the oxic portion of the columns. Overall, the highest removal of VOCs was observed in the column containing the compost/wood chip mixture. This study demonstrates that biocovers consisting of compost materials have the potential to attenuate trace gas emissions from landfills.
