論文概要:In this paper,Carbon emission reduction potential of demolition waste recycling in the residential building within a city scale aims to focus on the recycling of residential building demolition waste within urban areas to capitalize on the carbon compensation effect and promote sustainable development.
+
論文概要:This paper examines the carbon emission reduction potential of recycling residential building demolition waste on a city scale, focusing on leveraging the carbon compensation effect to promote sustainable development. Using a life cycle assessment approach, it evaluates carbon emissions and compensation during three phases: building demolition, waste transportation, and waste disposal.

The research specifically targets the evaluation of carbon emissions and carbon compensation from the recycling of residential building demolition waste. The whole life cycle assessment method is employed to define the boundary of carbon calculation in the residential building demolition phase, which is divided into three stages: building demolition, waste transportation, and waste disposal. Carbon compensation is considered during the reuse phase of building waste, and a carbon emission and compensation calculation model is established.
+
The findings reveal that waste disposal is the most carbon-intensive stage, contributing approximately 68% of total emissions. Recycling demolition waste emerges as a promising solution to offset these emissions. The study's ideal scenario demonstrates that recycling can reduce total emissions in the construction industry by 35.5% through carbon compensation.

Quantitative analysis reveals that carbon emissions are mainly concentrated in the waste disposal stage, accounting for approximately 68% of the total carbon emissions. Addressing carbon emissions at this critical stage could lead to a significant overall reduction in the construction industry's carbon footprint. Recycling building waste emerges as a promising solution to mitigate the carbon impact of demolition activities. The carbon compensation effect generated through the recycling process proves to be highly effective in offsetting carbon emissions from the demolition phase. Notably, in the ideal scenario set in this study, the carbon compensation effect from the recycling of building waste can significantly reduce the total carbon emissions from the construction industry by 35.5%. Furthermore, the research emphasizes the importance of increasing the reuse rate of demolition waste. As this rate rises, carbon emissions during waste disposal decrease linearly, while carbon compensation from reused building materials increases. This indicates that further emphasis on recycling and reusing building waste can lead to even greater carbon reduction outcomes, reinforcing the significance of sustainable waste management practices.
+
Moreover, increasing the reuse rate of demolition waste results in a linear decrease in emissions from disposal and a rise in carbon compensation from reused materials. This highlights the significant role of recycling and reuse in achieving greater carbon reduction and emphasizes the importance of sustainable waste management practices.
  
−
Overall, this research underscores the urgent need for sustainable practices in the construction industry to achieve carbon reduction targets. By focusing on the recycling of building demolition waste, policymakers and industry stakeholders can effectively contribute to carbon neutrality goals and facilitate the overall transition towards a more sustainable and low-carbon future.
+
The research concludes by advocating for enhanced recycling efforts to help the construction industry meet carbon reduction targets, align with carbon neutrality goals, and advance the transition toward a sustainable, low-carbon future.
