In the whole process route, the floor space, energy consumption, greenhouse gases, and gas pollutant emissions of each link are included in the scope of environmental impact assessment. When using this LCA data set, users should ensure that the data strictly corresponds to municipal sludge with a moisture content of 80% being transported for landfilling. Attention should be given to the transport distance, mode of transport, and local landfill operations, as these factors could significantly influence the environmental impact. For accurate modeling, inclusion or exclusion of sludge pre-treatment processes and the possibility of material recovery or recycling should also be considered.
