| Use advice for data set | When utilizing this data set for Life Cycle Assessment (LCA), it is crucial to ensure that the technological scope of the assessment aligns with the advanced machinery and production techniques employed in the described facilities. Consideration should be given to the replacement of traditional raw materials with mixed solid wastes when conducting an environmental impact assessment. Data users must also respect the defined system boundary, which is confined to the cement production system of the cement plant. For any extrapolation or comparison with other production methods and scales, proper scaling and normalization techniques should be applied. It's also recommended to monitor updates, as technology and production practices may evolve, potentially impacting the LCA results. |
| Technical purpose of product or process | The cement production data set represents ordinary Portland cement manufactured using the new dry process technology with a capacity of 5000 tonnes per day (t/d). This type of cement is widely used in general construction, including buildings, bridges, pavements, and other infrastructure projects. It may also be utilized for residential and commercial construction, due to its hydraulic properties and strength. The incorporation of mixed solid wastes suggests an environmental consideration in the production process, allowing for waste-to-resource strategies within the cement industry. |
