| Use advice for data set | Users of this Life Cycle Assessment data set should pay attention to the specific methodological aspects related to the inclusion of cement kiln dust recycling when calculating environmental impacts. The data is representative of typical production processes at the Beijing cement production base and should be considered in the context of Chinese infrastructure. Special attention should be given to the recovery and utilisation of energy from the dry rotary kiln process, as well as the direct emissions and heavy metal gas emissions data specific to the Beijing site. Users should note that this data is based on the annual average monitoring data and may need to be adjusted for site-specific conditions or changes in technology over time. |
| Technical purpose of product or process | The Portland fly-ash cement with a strength of 52.5 MPa produced in this industrial process is intended for use in construction applications requiring high strength cement. The dry rotary kiln technology with 100% cement kiln dust recycling is typically employed for the efficient production of cement, reducing waste and improving sustainability. |

| Model description | Choose to manage 1 ton of Portland fly ash cement (P·F 52.5).A dry rotary kiln scenario using 100% cement kiln dust recovery technology was considered. The infrastructure processes for each scenario, road transport of raw materials to the cement production site, direct emissions, wastewater treatment, raw material and energy production and the recovery of electricity from the dry rotary kiln scenario are included. |
