Comprehensive Recycling of Construction Waste

With China's urbanization process accelerated ceaselessly, construction developing rapidly, the great architectural waste discharge. At present, construction waste production but also has far exceeded the rate of domestic can bear. Meanwhile, the disposing mode, such as mechanical landfill and burned, resulting in huge waste of resources and environmental pollution. So how to efficiently processing and using reasonable construction wastes have become our country now faces a severe environmental and ecological problem. This paper discusses the causes, construction waste handling and processing components, the problems existing in the detailed analysis is introduced, and introduces some developed countries and regions with the application of construction waste disposal of the newest research achievement, and comparing and analyzing current construction waste comprehensive treatment of some problems existing in China, and finally puts forward some construction waste comprehensive reuse countermeasures. After Wenchuan earthquake, the state has issued the "earthquake construction waste processing guidelines" and other guidance documents, clearly proposes the specific requirements of re-using the construction waste comprehensively, that indicates the problem has caused attention increasingly by integrated parties. In recent years some scholars are researching physical properties of construction waste recycled aggregate and the methods of manual or mechanical separation of construction waste, that is multi-aperture sieve of separation, but still present, most research focused on construction waste recovery on the theory of technology, and for building integrated waste processing and safeguards to promote the application of research is relatively small.In the next period of time, China's construction industry will maintain rapid development trend, therefore, if we do not have a high degree of attention and management to the construction waste's produce and emission, it will not only make adversely affected to the implementation of our energy reduction, resource development, recycling economic and other policies, but also bound to obstacle and constraint the sustainable development of China's construction industry. So how to manage and effectively deal with these wastes has become the must focus on solving and can not be avoided problem in construcion industry.
