Use advice for data set When using this data set for Life Cycle Assessment, note that the provided information corresponds to a 'black box' approach for the company's cement production line, comprising the following stages: raw meal preparation, pulverized coal preparation, clinker calcination, and cement grinding, summarized as the 'two grinding and one burning' system. To account for the co-processing of waste materials, use the formula αp = W'p/(W'p + Wc + Wr) to allocate the data according to the energy and mass balance. The system boundary for assessment is set from raw meal preparation to cement grinding, taking 1 ton of cement product as the functional unit. Ensure the inclusion of waste co-processing in the LCA model and maintain consistency with the technological applicability and system boundary defined.

General comment Synergistic disposal is a production process that involves adding industrial waste as alternative raw materials and fuels at the raw material mill and kiln tail positions, specifically including waste clay, waste catalysts, and contaminated soil.The company's cement production line consists of a vertical raw material mill, a 5-stage preheater, a rotary kiln, and a large ball mill (cement mill) equipped with a roller press, as well as equipment for crushing, grinding, and conveying limestone and gypsum. The production system is referred to as the "two mills and one kiln" system, namely the raw material mill, cement mill, and rotary kiln incineration.

Technical purpose The described cement production process is intended for the manufacture of Portland-composite cement using the modern dry process rotary kiln technology with a capacity of 4000 tonnes per day. This production line is equipped to co-process mixed solid wastes as alternative raw materials and fuels. Specific industrial wastes such as waste clay, waste catalysts, and contaminated soil are utilized in the production process. The cement produced is suitable for use in various construction applications where Portland-composite cement is required.
