Research On Reverse Logistics Of Construction Solid Waste Based On Recycling Economy

For a long time, human live a high pollution and high consumption life. With thehigh-speed economic development, resource shortage, environment pollution has been created.In order to cope with the increasingly prominent environmental problem, our country putsforward the sustainable development of a national strategy, and the development of "circulareconomy" is an important way to realize the sustainable development. Construction is one of themost important activities of the economic activities, construction and related activity consumesabout fifty percent of the world’s energy and material and caused serious pollution. Therefore,we have to put the concept of circular economy into the building engineering for realize thesustainable development.At present, the research of reverse logistics in China is still in its beginning stage,researches which connect building engineering and reverse logistics are rare. In practice, ourcountry construction produce a large amount of solid waste is still based on the simple landfill asthe main processing mode; it is waste a lot of resource. Based on the analysis and summary ofexisting literature, this thesis first summarizes the related theories of the reverse logistics andconstruction waste disposal, and research the present situation and experience of building solidwaste treatment at home and abroad, it is pointed out the drawback of China’s current buildinglogistics system, analyze the income of implement reverse logistics. Then, this thesis constructsthe network of reverse logistics of building solid waste, and optimizes this network by mixedinteger double model. This model constructs two different target functions from two aspects ofadministrative decision-making and construction enterprise. Based on the study of in theforegoing, this thesis give suggestions and countermeasures to relevant parties aboutimplementing of reverse logistics of building solid waste.
