Recently, an environmental project in Shenzhen has drawn widespread attention: workers are excavating garbage buried nearly 20 years ago from landfills and transporting it to incineration plants for processing. Behind this move lies the dual pressure of scarce urban land resources and stricter environmental standards. In the past, Shenzhen primarily relied on landfilling for municipal solid waste disposal. However, as the city expanded, these landfills not only occupied valuable land but also posed environmental risks such as leachate contaminating groundwater and methane emissions. In recent years, Shenzhen has actively promoted the construction of a ‘zero-waste city,’ encouraging waste-to-energy incineration to achieve resource recovery. Excavating aged waste aims to reclaim land, eliminate pollution hazards, and convert waste into energy using modern incineration technology. Experts note that although the process is costly, it enhances the city’s long-term sustainability. This initiative also reflects China’s broader shift in urban solid waste management—from end-of-pipe disposal toward source reduction and circular utilization.
近日，深圳一项环保工程引发广泛关注：工作人员将埋藏近20年的垃圾从填埋场挖出，运往焚烧厂进行处理。这一举措背后，是城市土地资源紧张与环保标准提升的双重压力。过去，深圳主要依赖填埋方式处理生活垃圾，但随着城市扩张，原有填埋场不仅占用宝贵土地，还存在渗滤液污染地下水、甲烷排放等环境风险。近年来，深圳大力推动‘无废城市’建设，鼓励垃圾焚烧发电，实现资源化利用。此次挖掘陈年垃圾，正是为了腾退土地、消除污染隐患，并通过现代焚烧技术将垃圾转化为能源。专家指出，此举虽成本较高，但长远看有助于提升城市可持续发展能力。同时，这也反映出中国在城市固废管理方面正从‘末端处置’向‘源头减量+循环利用’转型。
