建筑垃圾处理的碳减排作用分析

Analysis of Carbon Emission Reduction Effect of Construction Waste Treatment

绿色建造作为新型建造方式,贯穿建筑全生命周期。建筑垃圾变为再生绿色建材,不仅成为绿色建造的物质基础,且将建筑全生命周期的绿色低碳循环变为现实。从建筑垃圾的减量化、资源化、无害化等方面深入分析各子目标实施过程所面临的具体问题,并有针对性地提出实施重点。通过有无对比法对具体项目进行碳减排定量测算,发现每综合利用1t建筑垃圾可减少CO_(2)排放量约0.698t。建筑垃圾的有效处理,有助于提高行业资源利用效率、完善绿色低碳循环发展体系。

Green construction as a new construction method, throughout the whole life cycle of the building. The transformation of construction waste into recycled green building materials not only becomes the material basis of green construction, but also turns the green and low-carbon cycle of the whole life cycle of the building into reality. The specific problems faced in the implementation of each sub-target are analyzed in depth from the aspects of reduction, resourceization and harmlessness of construction waste, and implementation priorities are proposed in a targeted manner. Through the quantitative carbon emission reduction calculation of specific projects with and without comparison method, it is found that each comprehensive utilization of 1t construction waste can reduce CO_(2)emissions by about 0.698t. The effective treatment of construction waste can help improve the efficiency of resource utilization in the industry and improve the green low-carbon cycle development system.
