Use advice for data set
| When utilizing this data, ensure that the system boundary includes the anaerobic digestion of sludge as well as any upstream and downstream processing stages relevant to the lifecycle of the sludge. For the functional unit, consider one ton of dry sludge as the reference amount for comparison and impact analysis. Include considerations for the ultimate disposal of digested sludge and the possibility of energy recovery, such as biogas production, within the assessment. |
|
Technical purpose of product or process
| This data set is applicable to environmental impact assessments for municipal sludge treatment and disposal processes, specifically the part of the process involving the anaerobic digestion of dry sludge. It is relevant for assessing the environmental footprint of waste management systems and can be used to evaluate the sustainability of sludge treatment facilities. |

|
| Several typical sludge treatment facilities in China, representing anaerobic digestion, composting, co-combustion, thermal drying-incineration, and cement production, respectively, are selected to carry out the inventory. Data are mainly taken from the site-specific measurement, either by field survey or by operation report. Sludge characteristics are based on the average values of the sites investigated. |

Technology description including background system
| In order to investigate the effect of anaerobic digestion, each system is further divided into two subunits: one is the baseline case , while the other is in combination with anaerobic digestion. Anaerobic digestion is conducted prior to dewatering. |
