| Abstract | Many Countries in Southeast Asia nowadays face with hazardous waste discharge from industrial and human activities. Cement kiln using hazardous waste such as PCBs/ POPs as alternative fuel not only can help saving fuel cost but also to destroy the hazardous waste efficiently. But, before got license from government to firing hazardous waste, cement kiln must be monitored to assess its impact to surrounding environment. Baseline monitoring must be carefully conducted to estimate the impact levels when no hazardous waste is burnt. SCCC's kiln 05 was selected for monitoring in this research with the focus on the stack emission of SPM and BTEX level. The ambient air measurements were also conducted for SPM, BTEX and PCB by High-Vol and Mini-Vol equipment. For stack, US.EPA Modified Method 5 monitoring was used. Alternative wastes feeding to SCCC's kiln 05 arranging from 5 - 15% of coal heating value so that to have enough heating values for cement kiln operation. Totally 7 ambient air samples collected with TSP ranging from 191 to maximum value is 220 g/m3 which did not exceed Thailand Ambient Air Quality Standard. Benzene concentration is widely fluctuating from 1.9 to 5.2 g/m3. 9 PCB congeners were analyzed but only 5 PCB congeners were found in ambient air samples. Other pollutant parameters measured in ambient air also did not exceed Thailand standard. Overall, 6 stack samples collected in SCCC's kiln 05 which showed low BTEX value and SPM quite widely fluctrated from 9.6 to 13.7 mg/m3. All gaseous pollutants of HC1, NOx, SOx, CO were not exceeded Thailand standard for cement kiln emission. All 5 PCB congeners were found in the stack gas with higher level in the gaseous phase. The baseline monitoring at SCCC's should be further monitored including the operation without waste co-fueling. More toxic PCBs, especially those non-orthor PCBs should be included in the future study. |
