建筑废弃物的回收原理与方法研究

由于社会和经济因素的要求，当今的建筑生命周期要最大程度地完成圆形的循环过程，即重新使用拆建物料制造新产品。循环经济的大背景下，承建商通过坚实的理论基础，采用分层次的方法来进行建筑废弃物的管理。文中总结了两种方法的优点和缺点，进行了混合回收与源头分离两种方法的比较研究。最值得注意的是两个不同的意向方案：绿色星球计划和ICC—ESSAVE^TM方案。突出的可持续认证和设计方案及绿色星球计划侧重的能源效率模型时常被繁重调试系统的LEED所青睐。一旦被国际编码理事会所批准，这些文件可以在LEED的评分系统下或绿色星球计划中，帮助其寻找资格评分。文章最后分析了建筑废弃物的回收流程，并得出结论：高达95％的建筑和拆迁建筑废弃物都可以回收；回收相比垃圾填埋更节省资金；源头分离较混合回收需要更多的管理和劳动力，但能获得更大的经济利益；承建商应该组织和管理现场的回收工作。

Research on construction waste recycling principles and methods

To the greatest extent possible, the requirements of social and economic factors, today＇ s building life cycle to complete the circular loop process, the re-use construction and demolition materials to manufacture new products. The backdrop of the circular economy, solid theoretical foundation contractor, using the hierarchical method of construction waste management, the paper summarizes the advantages and disadvantages of the two methods. Comparative study of the mixed recycling and source separation of the two methods. The most noteworthy is the program of the two different intentions： the green planet, plans and ICC-ES SAVETM program. Prominent sustainable certification and design and green planet intends to focus the energy efficiency models have often been heavy debugging system LEED ages. Once they are approved by the International Code Council, these files can be in the plan of the LEED rating system or green planet, to help them find the qualification score. Finally, analysis of construction waste recycling processes, and concluded： up to 95% of the construction and building demolition waste can be recycled; recycling compared to landfill more to save money; source separation requires more management than the mixed recycling and labor, but to obtain greater economic benefits; contractor should organize and manage the scene of the recovery work.
