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.
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.
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.
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.
