建筑废弃物资源化利用产业现状及发展趋势

Resource utilization of construction waste,current situation and development trend of industry

近几年,我国各地进行基础设施改造、城镇综合整治等工程,建筑废弃物产生量与日俱增。建筑废弃物的不规范处置,资源化利用率低,不仅浪费了大量的土地资源,对土壤和水环境造成破坏,而且随之产生的污染物已经成为可吸入颗粒物——PM2.5主要源头之一。通过分析国外建筑废弃物相关政策、处置方式和模式,对比国内在该领域的不足,以上海为参考点,提出应对建筑废弃物资源化利用的对策和建议。同时,为各地建筑废弃物资源化利用发展趋势提供参考方向。

In recent years,infrastructure renovation and comprehensive urban renovation projects have been carried out in different regions in China,and the production of construction waste is increasing day by day.Irregular disposal of construction waste and low utilization of resources not only waste a lot of land resources and damage the soil and water environment,but also produce pollutants that have become one of the main sources of PM.inhalable particulate matter.Based on the analysis of foreign policies,disposal methods and modes of construction waste,and the comparison with domestic deficiencies in this field,this paper put forward countermeasures and suggestions for the utilization of construction waste as a resource.At the same time,it provides a reference for the development trend of construction waste resource utilization in various areas.
