| Use advice for data set | When using this dataset in life-cycle assessments (LCA), it is crucial to ensure that the scope of the LCA appropriately reflects the management of one tonne of dry sludge as the functional unit. Consider factors such as geographical relevance to the Maidao sewage treatment plant and the technological applicability of dewatering processes. Users should also account for possible variations in emissions and resource usage based on local operating conditions. The dataset is specialized and may not be applicable to dissimilar wastewater treatment contexts or different sludge treatment technologies. |
| Technical purpose of product or process | This dataset describes the process of municipal sludge treatment and disposal through dehydration at the Maidao sewage treatment plant. It is intended for use in life-cycle assessments that require data on the environmental impact of managing dry sludge (DS). This information can be applied for comparative studies and environmental evaluation of wastewater treatment processes, specifically focusing on dewatering one tonne of dry sludge. |
