Comparative Analysis of Existing Life Cycle Inventories of Cement in China

Abstract:

Life cycle inventory (LCI) involves creating an inventory of flows from and to nature for a product system, which is a prerequisite of life cycle assessment (LCA). This paper conducts a comparative analysis of available inventories of cement produced in China and points out the reliability of these inventory results. 1 ton cement was chosen to be the functional unit, and the system boundary was defined from cradle to gate. In the process of cement production, many pollutants will be emitted, so only the four main emissions (CO2, NOX, SO2 and dust) are considered. The analysis showed that the reliability of cement inventories is affected by inaccurate or non-representative data, and all results are difficult to compare due to the varying system boundaries.
