| Use advice for data set | When using this data set for life cycle assessment, the selected functional unit is the management of one tonne of dry sludge (DS). Ensure the treatment process being compared in the life-cycle inventory is equivalent in the terms of the functional unit. For modeling purposes, explicitly account for all outputs, including any biogas produced during anaerobic digestion, and consider the final disposition of the digested sludge. Additionally, evaluate the local technological practices for potential variability in the data. |
| Technical purpose of product or process | This data set describes the process used at the Maidao sewage treatment plant for the treatment and disposal of municipal sludge. The anaerobic digestion of dry sludge is intended for reducing the volume and mass of waste, biogas production, and potentially for energy recovery and soil amendment applications. This process can serve municipal waste management systems by transforming biodegradable sludge into stabilized products used in various sectors. |
