The Life Cycle Assessment of Carbon Dioxide Emission of Four Major Sewage Treatment Plants in Taiwan

Abstract:

The sewage comes from buildings is drained into public sewers. The sewage is then treated in a sewage treatment plant to meet the sanitation standards before being discharged to the water cycle in nature. The sewage treatment process consumes energy and produce CO₂. In this research, the idea of streamlined life cycle assessment was applied. The CO₂ emission of sewage treatment was assessed from direct energy consumption of four major sewage treatment plants in Taiwan. The results show that the unit CO₂ emission of sewage treatment calculated from four plants is 0.174 kg-CO₂/m³. The CO₂ emission at in-plant sewage treatment stage takes more than 95% of total CO₂ emission for most plants. The results suggest that CO₂ emission of sewage treatment can be calculated from energy consumption at in-plant sewage treatment stage to simplify the calculation. This database will be important reference for water resource research.
