- Abstract
Urban construction production increases significantly in China because of the continuous speed and large scale of urbanization. Accordingly, environmental pollution caused by construction waste intensifies. With the growing significance of ecological civilization construction, urban development projects are under pressure to apply energy-saving and environmentally friendly methods. Recycling of construction waste resources can effectively reduce the environmental pollution of such wastes, thereby achieving sustainable urban development. To further analyse environmental pollution hazards caused by urban construction wastes, construction waste resource recycling measures were proposed. A case study based on central China was conducted and extensive studies on construction waste recycling in the context of developed territories (Europe and America) were reviewed. Environmental pollution damage caused by urban construction wastes was also identified. Then, the environmental pollution status generated by urban construction wastes was analysed and the causes of urban waste recycling barriers were summarized. Finally, measures for urban construction waste recycling were proposed. Results show that America, Japan, and Germany have achieved high construction waste recycling rates. Environmental pollution hazards from urban construction waste are manifested by large-scale occupation of land resources, resulting in intensifying domestic water, soil, and air pollution. High waste production and low comprehensive utilization rate of construction waste caused by urban construction scale are two aspects of current urban construction waste pollution. The main causes of the low recycling rate of urban construction wastes involve a lack of supporting laws and regulations as well as industrial policies, low market shares of constructionwaste recycling products, poor coordination of key nodes in the industrial chain, and low benefits of recycling products. Research conclusions provide good references for improving the overall development level of urban construction recycling, facilitating continuous development of construction waste recycling industrialization, and formulating construction waste recycling policies and development plans in other regions in China.
