Use advice for data set Users should apply this Life Cycle Assessment (LCA) data set with consideration of its defined technological scope: raw meal preparation, clinker burning, cement grinding, and packaging and delivery processes for ordinary Portland cement with a daily production rate of 2000-4000 tons. When utilizing the resource consumption, energy consumption, and emissions data, it is critical to reference the data sources mentioned, including the research results by Li Songbing, publications by the Cement Industry Association, the 2010 Cement Industry Risk Analysis Report, and the 2008 China pollution source census statistics. CO2 emissions figures should be used with understanding of their specific sources and the calculation method, which is dividing by 0.7 to derive unit cement heat consumption based on heat input. Methodological considerations such as allocation rules, cut-off criteria, and any assumptions must be explicitly acknowledged in the interpretation of the LCA results. |
