On December 20, 2015 at 11:40 am a landslide in one of China's most advanced cities, Shenzhen, killed 73 people and damaged 33 buildings. In the absence of heavy rainfall or earthquakes, the landslide was an unexpected and profound shock to many people. According to China's Ministry of Land and Resources, the landslide was triggered by the collapse of an enormous pile of construction and demolition waste (CDW). With China's rapid urbanization, an increasing amount of CDW is being generated, especially in major cities. In total, China produces some 30% of the world's municipal solid waste and of this about 40% is CDW. To prevent landslides associated with CDW, the volume of waste dumped in landfills should be regulated. More specifically 4-Rs (reduce, reuse, recycle and recover) policies should be implemented more widely and efficiently. Although landfill will continue to be an important disposal option, proper management and careful monitoring of CDW are urgently needed to satisfy pressing safety issues. International collaboration, sharing of knowledge, and use of the latest technologies are needed so that the similar landslides can be prevented in China and elsewhere.
2015 年 12 月 20 日上午 11 点 40 分，中国最先进的城市之一深圳发生山体滑坡，造成 73 人死亡，33 栋建筑受损。在没有强降雨或地震的情况下，这场山体滑坡让许多人感到意外和震惊。中国国土资源部表示，此次山体滑坡是由大量建筑和拆迁废物（CDW）的坍塌引发的。随着中国的快速城市化，越来越多的 CDW 正在产生，尤其是在主要城市。中国总共产生了约占全球城市固体废物 30%的废物，其中约 40%是 CDW。为了防止与 CDW 相关的山体滑坡，应该规范垃圾填埋场倾倒的废物量。更具体地说，应该更广泛、更有效地实施 4R（减少、再利用、再循环和回收）政策。尽管垃圾填埋仍将是一种重要的处理选择，但迫切需要对 CDW 进行适当的管理和仔细的监测，以满足紧迫的安全问题。需要国际合作、知识共享和使用最新技术，以防止中国和其他地方发生类似的山体滑坡。
