Study on eco-utilization and treatments of highway greening waste

摘要

With the rapid development of highway greening protection construction, the amount of greening waste is continuously increasing, including litter, pruning and turf cutting litter and so on. As the traditional treatment approach of greening waste, such as incineration, landfill could not meet the requirement of sustainable development, the harmless and resourceful treatment method of greening waste becomes the necessary trend. In order to reasonably dispose and make use of the increasing litter, from the ecological resources point of highway greening waste, on the basis of ecological functions of litter, the several ecological utilization ways of greening waste were overviewed, moreover composting treatment technology of greening waste and its advantages, product development, application effect and market prospect were highlighted, it is thought that the composting is the effective utilization approach for greening waste, it has fairly good social benefit and ecological benefit, which can provide one kind of practical and feasible pattern for developing circular economy of highway greening industry. At the same time, being lacked of corresponding policy support and management requirement of greening waste utilization in China, the countermeasures and suggestions suitable for China of green waste recycling utilization were put forward by learning from the foreign successful experience and policy in this paper.
