Use advice for data set
| When utilizing this data set for Life Cycle Assessment (LCA), ensure that the sludge processing conditions mirror those specified (e.g., moisture content of 80% and pyrolysis temperature of 850℃). For the impact assessment phase, consider the potential outputs and their treatment methods, such as syngas production, char utilization, and liquid effluent treatment. Exclude the impacts of upstream processes (such as sludge collection and transportation) and include any significant emissions during the pyrolysis step. |
Technical purpose of product or process
| The municipal sludge treatment and disposal process described represents a unit process for the pyrolysis of wet sludge with a moisture content of 80% at a temperature of 850℃. It typically serves the purpose of converting wet municipal sludge into more stable materials, which can be used for energy recovery, soil amendment, or further chemical processing. The functional unit for this process is defined as the treatment of 1 ton of municipal sludge. |
