| Use advice for data set | When utilizing this data set for life cycle assessment, ensure that the scope of your analysis includes the management of one ton of dry sludge (DS) as the functional unit. Consider any regional regulations and impacts on soil health and agricultural productivity. The data should account for all stages of sludge processing, from treatment to agricultural application, including energy and chemical inputs. Pay attention to potential environmental impacts such as emissions and nutrient runoff in your assessment. |
| Technical purpose of product or process | This data set pertains to the process of municipal sludge treatment and disposal with the specific end use of dry sludge in agriculture. The dry sludge is used as a soil amendment and fertilizer, providing a beneficial reuse of waste materials for enhancing soil properties and crop production. |
