| Use advice for data set | When utilizing this data set for Life Cycle Assessment, it is important to ensure that the boundaries of the analysis accurately reflect the landfill disposal phase of municipal sludge with a corresponding moisture content of 80%. The functional unit of 1 tonne of sludge should be applied consistently across the study when assessing environmental impacts, resource consumption, and economic costs associated with the landfill process. Consideration should be given to any emissions generated, energy and materials used, and related activities up to the point of landfilling. Specific attention should be paid to regional variations in sludge composition, treatment technologies, and regulations. |
| Technical purpose of product or process | Municipal sludge treatment and disposal process that handles wet sludge with a moisture content of 80%, intended for landfill operations. The process is a unit operation designed to manage and neutralize municipal sewage sludge, making it suitable for safe disposal in landfills. This includes dewatering procedures that reduce the moisture content of sludge and prepare it for subsequent handling or treatment phases. |

| General comment on data set | Sludge landfill will produce a large amount of leachate, and various components in the leachate, especially heavy metals, will have a greater impact on the surrounding soil and water environment, because the landfill leachate data is difficult to obtain, the amount of leachate produced in this paper is estimated to be 5% of the sludge mass according to the literature, and the content of each component refers to the filtrate produced by mechanical compression of sludge in sewage treatment plant. |

| Functional Unit | In this paper, 1 t of 80% sludge with a moisture content is used as the functional unit for calculating environmental impact, resource consumption and economic cost. |
| Technological representativeness | |
| Technology description including background system | Using the traditional landfill process, the sludge is simply sterilized and then directly landfilled. |
