Use advice for data set This data set represents the actual production data of 1kg of cement clinker from Shandong Luban Chemical using a rotary kiln calcination process. The inventory includes all major raw materials and all required energy inputs. Exclusions are the production processes of raw materials and minor energy flows (less than 1%). Users should note that infrastructure, services, or auxiliary facilities have been systematically excluded. This data is intended for Life Cycle Assessment studies of cement products and should be used in accordance with standard LCA methodology, considering the technological applicability to the specific context of the LCA study.
Technical purpose of product or process The cement clinker produced in this traditional rotary kiln process by Luban Chemical Industry is used for the manufacture of various types of cement. The high-temperature calcination process employed, known as the 'one-step' process, is specific to the production of cement clinker which is a critical component in the construction industry for creating concrete.
