• Key policies to promote the CDW recycling are quantitatively explored. • The stepwise regression was employed to evaluate the effect of the nine policies. • Green product label is the top policy followed by Charge and Tax and Technical Standard. • 84.6% of the sample cities employed the Charge and Tax. • The ratios were only 11.5% for Technical Standard and 7.7% for Green Product Label. There is a growing need to recycle construction and demolition waste (CDW) in order to treat the huge amount of CDW in many metropolises of China. However, the CDW recycling industry is still in its initial stage and developed unevenly across various areas of China. In spite of some qualitative discussions, the quantitative analysis of crucial policies to the development of CDW recycling industry was overlooked. Through literature review, nine influential policy instruments were identified in term of three categories, i.e. control and command policy, market-based policy and information-based policy. The stepwise regression analysis was employed to explore the relationships between the influential policies and the development level of CDW recycling industry in 52 sample Chinese cities. The results demonstrated that Green Product Label, Charge and Tax and Technical Standards had statistically significant association with the development of CDW recycling industry in sample cities. In the surveyed cities, Charge or Tax was the most common policy tool (84.6%), but Green Product Label (7.7%) and Technological standards (11.5%) were rather less frequently employed. According to the results, Green Product Label and Technical Standards should be given higher priority. In addition, landfill charge should be introduced as a fundamental impetus. These results provide directions for other cities to facilitate the development of their CDW recycling industry. [ABSTRACT FROM AUTHOR]

The large scale of construction waste has significant impacts on the environment which has attracted a growing public concern in China. Despite the introduction of measures on construction waste reduction, outcomes are not always satisfactory. This paper aims to explore critical factors that influence the construction waste reduction (CWR) behavior of contractor employees. A hypothetical model was developed in the first instance by incorporating additional variables (knowledge and personal norm) into the classic theory of planned behavior (TPB) model. The extended TPB model was consequently tested via the structural equation modeling (SEM) using data collected from the Shenzhen city, which is the first national pilot city for construction waste management and comprehensive utilization in China. This study revealed that the extended TPB model has significantly improved the explanation power of CWR behavior than the classic TPB model. Results showed that contractor employees' behavior-related knowledge was the most influential factor on their CWR behavior, notably greater than subjective norm, attitude, personal norm and perceived behavioral control. These findings provide useful inputs for designing effective approaches to motivate CWR behavior of contractor employees and policy making to reduce construction waste. [ABSTRACT FROM AUTHOR]
