| Use advice for data set | Users of this dataset should note that while the technological process accounts for the use of urban domestic waste as a secondary fuel, environmental burdens associated with the consumption of clay resources are currently excluded from the analysis. Additionally, the environmental impacts caused by the use of iron powder as an iron correction material are also excluded. Emission data at the output end of the product system include nitrogen oxides, sulfur dioxide, carbon dioxide, and dust. When applying this dataset, ensure that it aligns with the specific context of your LCA study and that the bounds of the evaluation scope match your system boundaries. |
| Technical purpose of product or process | This dataset represents an ordinary Portland cement production process using a new dry process rotary kiln and incorporating the incineration of municipal waste as a secondary fuel. The cement produced, with a 28-day compressive strength of 42.5MPa, is typically used in construction applications requiring high-strength concrete. |

| Model description | The functional unit is the performance of 1kg cement with a 28-day compressive strength of 42.5MPa, that is, 1Fu=42.5kgMPa. The scope of evaluation is raw meal preparation, clinker calcination and cement preparation. The environmental load caused by the consumption of clay resources is not considered for the time being. Iron powder is an iron correction material, and its environmental impact will not be considered. The wastes considered to be emitted at the output end of the product system mainly include nitrogen oxides, sulfur dioxide, carbon dioxide and dust. |
