Abstract

Due to the large-scale demolition waste generated by large-scale urban renewal projects, the environmental impacts caused by the demolition wastes during recycling cannot be ignored. However, existing research lacks the entire life cycle carbon emission assessment of demolition waste, and few studies involve the removal of carbon emissions from the waste recycling stage. In order to quantitatively evaluate the environmental impacts of the fixed disposal of demolition waste, this study uses the entire life cycle assessment theory, based on the basic data of energy consumption in four stages of demolition stage, collecting and sorting, transportation, and recycling stage. Considering the environmental cost and environmental benefit of the entire life cycle of fixed disposal, the environmental impacts assessment model of the entire life cycle of fixed disposal is established. The carbon emissions generated by fixed disposal at all stages of the life cycle were measured, and the environmental benefits of recycled building materials were taken into account to compare with the carbon emissions generated by traditional landfill. Exploring the causes of carbon emissions from various stages of fixed disposal and the environmental benefits of recycled building materials produced during the waste recycling stage, proposing energy-saving and emission reduction, and determining the fixed disposal method for low-carbon emission demolition waste, have reference value. The study can effectively evaluate the environmental benefits of fixed disposal, and provide a reference for the development of demolition waste resource management policies.
