摘要/Abstract

摘要： 建筑废弃物资源化利用具有较显著的碳减排效果和低碳示范效应,但相关减排项目开发缺少适用方法学。本研究旨在开发建筑废弃物再生骨料替代天然骨料的碳减排核算方法学。在界定适用范围为建筑废弃物资源化利用工厂的项目活动后,方法学构建采用障碍分析法识别并论证基准线情景,采用基准线排放与项目排放差额对比法及碳排放因子法核算减排量。监测方法规定了设计阶段和实施阶段所需的参数和数据,其中实施阶段应重点监测资源化利用生产线的各类能源消耗、废弃物处理量及再生骨料产出量。以江苏省某实际项目为案例,研究验证了方法学的有效性和可行性。研究结果不仅填补了建筑废弃物资源化利用领域温室气体自愿减排方法学的空白,也从碳减排核算的角度丰富了建筑废弃物资源化循环利用的市场化行动方案。

Abstract: The resource utilization of construction waste has significant carbon reduction and low-carbon demonstration effects. However, the development of related emission reduction projects lacks applicable methodologies. This study aims to develop a carbon reduction accounting methodology for the replacement of natural aggregate with recycled construction waste aggregate. After defining the scope of application as the project activities of construction waste resource utilization factories, the methodology development adopts obstacle analysis method to identify and demonstrate the baseline scenario, and uses the difference comparison method of baseline and project emissions and the carbon emission factor method to calculate the emission reduction. The monitoring method specifies the parameters and data required for the design and implementation phases, with a focus on monitoring the various energy consumption, waste treatment volume, and recycled aggregate output of the production line during the implementation phase. The study verified the effectiveness and feasibility of methodology using a real project in Jiangsu Province. The results of this study not only fills the gap in the methodology of voluntary greenhouse gas reduction in the field of construction waste resource utilization, but also enriches the market-oriented action plans for the resource recycling utilization of construction waste from the carbon reduction accounting perspective.

Key words: construction waste, recycled aggregate, natural aggregate, carbon emission reduction accounting, methodology
