The main background resources consumed in the cement-making process from solid waste in the entire industry are electricity, coal and energy consumed in road transportation. In order to ensure the unification of the basic data for evaluation and the usability of the cases in this study. The life cycle model list of high-voltage electricity commercially available in China is used for electricity, the life cycle model list of coal commercially available in China is used for coal, and the life cycle model list of world-wide truck road transport is used for road transportation.2. The raw materials consumed in the process can be divided into raw materials and mixing materials. The raw materials consumed mainly include: carbide slag, calcium carbide furnace dust collection ash, purified ash, fly ash, slag, silica sand, steel slag, copper slag . The raw materials of the mixing material mainly include: desulfurization gypsum, fly ash, citric acid residue, and crushed limestone. All raw material input values come from the actual production data of the company.3. The main pollutants produced in the process include waste gas, waste water and solid waste. Exhaust gas is mainly CO2, SO2, NOx, etc. emitted during the production process. Wastewater is mainly cooling water and washing water used in the production process. Solid waste is mainly collected fly ash that can be recycled and reused and unrecyclable chlorine-containing residues. Among the above-mentioned pollutants, the emissions of SO2, NOx and atmospheric particulate matter are recorded and recorded through real-time monitoring and statistics by the enterprise. The amount of CO2 emissions is calculated based on the limestone content in the raw materials and the amount of coal burned, combined with the carbon content in the composition analysis results.4. Industrial solid waste raw materials come from surrounding power plants and chemical plants. The transportation methods are truck road transportation outside the factory and crawler transportation inside the factory. The longest road transportation distance does not exceed 200km. The movement of raw materials within the factory relies on electric crawlers and is not included in the transportation distance. 收集了水泥生产工艺中各阶段的物料、能量输入输出数据。其中，物料、能量输入输出数据来源于企业生产记录，1.全工业固废制水泥工艺中主要消耗的背景资源为电力、煤炭及公路运输过程中消耗的能源，为保证评价基础数据的统一及对本研究中案例具有可用性。电力采用中国市售高压电生命周期模型清单，煤炭采用中国市售煤炭生命周期模型清单，公路运输采用世界通用货车公路运输生命周期模型清单。2.工艺中消耗的原料可分为生料原料和拌和料原料，消耗的生料原料主要包括：电石渣、电石炉收尘灰、净化灰、粉煤灰、炉渣、硅砂、钢渣、铜渣。拌和料原料主要包括：脱硫石膏、粉煤灰、柠檬酸渣、碎石灰石。所有原料投加数值均来自企业实际生产数据。3.工艺中主要产生的污染物包括废气、废水及固体废弃物。废气主要是生产过程中排放的CO2、SO2、NOx等。废水主要是生产过程中使用的冷却水和洗涤用水。固体废弃物主要是收集到的可回收再利用的飞灰与不可回收的含氯残渣。上述排放的污染物中，SO2、NOx及大气颗粒物排放量通过企业实时监测记录统计，CO2排放量由原料中石灰石含量及燃煤量，结合成分分析结果中含碳量进行计算得到。4.工业固废原料来源于周围的发电厂、化工厂，运输方式为厂外货车公路运输及厂内履带运输，最长公路运输距离不超过200km。原料在厂内的移动依靠电动履带，不计入运输距离当中。 None 无 None 无 宋晓玲, 梁智霖, 罗维, 黄东, 杨忠, 徐盼盼, 胡敬平, 侯慧杰, 刘冰川, & 杨家宽.
