| Continue to promote urbanization brings the development of the construction industry, but it also generates a lot of consumption of energy, resource and the growing number of construction waste. On the one hand, construction waste require huge tracts of land, pollute the environment. On the other hand, there is a close relationship between the building construction dust and haze. Therefore, under the guidance of energy-saving emission and the concept of circular economy, the green construction as the breakthrough point, the "green" into the construction industry has become inevitable.In this paper, the green construction as a guide, reducing construction waste as the goal. Referring to the experience of domestic and foreign relevant treatment of construction waste. Through the review of the literature, questionnaire survey, data analysis and other aspects, to explore issues related to waste reduction under the guidance of the green construction. For the current development of the industry to put forward valuable opinions.(1) Through literature and data, analysis of the current situation of domestic and foreign construction waste processing and quantitative research. According to the different ways assort construction waste. Discuss the different stages of production waste.(2) Combined with the relevant requirements of green construction, and analysis inside and outside, individual, society four aspects to analysis the influencing of construction waste. Explore the various factors in the context of circular economy, energy-saving.(3) Design the questionnaire framework through the green construction requirements as well as the impact factors of construction waste. The questionnaire start from the personal information, factors affecting judgment, construction waste output ratio and others, divided into four parts. Trying to present the main factors of construction waste at the Pearl River Delta region. The questionnaire contains eight levels of impact,19 specific factors, as well as concrete, wood template of six categories of construction waste rate. This research for the construction and related industry professionals at the Pearl River Delta region, to complete the questionnaire online or field investigation.(4) Based on the results of the reliability and validity analysis, factor in order of importance, principal component analysis, T test, etc. by SPSS and Numbers software, conclude that management systems, planning and design, cost and construction materials are the most important factors in construction waste output. In addition to the management system factors that determine the various other factors which vary depending on the differentoccupation and working life of the interviewed persons. Also through the main component analysis,19 specific factors can be classified into six main components and there is a linear relationship to a certain extent.(5) According to the "green construction evaluation table" and other related requirements of green construction, expounds the main part of the waste produced in construction and the measures to reduce waste. Put forward the new materials, new technology, and some ways of the waste recycling, to reduce the use and waste of material. Methods also provide about materials reuse, to reduce the construction waste in the construction.Hope that through the research results of this thesis can have certain reference significance for the construction industry to further strengthen the waste management. At the same time, provide reference for formulate laws to the government and the development of industry specifications. More important is our research can made practical significance for the construction enterprises to reduce production waste from the process of construction. We should take the first step from the subtle environmental protection. |
