摘要/Abstract

摘要： 固体废物低碳资源化处理技术是中国实现碳中和的关键路径之一。为探究骨料全生命周期的碳排放特征，以固废基瓷化骨料和传统黏土骨料为研究对象，基于构建的骨料全生命周期碳排放计算模型进行对比分析，并利用敏感性和情景分析辨识碳减排关键因素。结果表明：黏土骨料和固废基瓷化骨料的全生命周期碳排放量分别为313.70和291.19 kg/t，其中骨料生产阶段碳排放占比最大（分别为84.59%和85.08%）。运输碳排放因子和原料消耗量是影响骨料全生命周期碳排放的主要影响因素。未来固废基瓷化骨料行业可以从使用电动重卡代替柴油重卡、提高赤泥等工业固废原料掺量以及优化电力结构方面实现固废再生骨料行业的碳减排。

Abstract: Low-carbon resource recovery technologies for solid waste are one of the key pathways for attaining China’s carbon neutrality agenda. A lifecycle carbon emission assessment model for aggregates was constructed for comparative analysis, and sensitivity and scenario analyses were conducted to identify key factors influencing carbon reduction. Results show that the lifecycle carbon emissions of clay-based aggregates and solid-waste-based porcelain aggregates are 313.70 and 291.19 kg/t, respectively, with the production stage contributing the largest proportions (84.59% and 85.08%,respectively). The carbon emission factors of transportation and raw material consumption are the main factors influencing the lifecycle carbon emissions of aggregates. In the future, the solid-waste-based porcelain aggregate industry can achieve carbon reduction through the following three measures: replacing diesel heavy trucks with electric heavy trucks, increasing the blending ratio of industrial solid wastes such as red mud, and optimizing the grid power. These integrated solutions provide a systematic framework for carbon reduction in the recycled aggregate industry while advancing circular economy objectives.
