深圳正全面推进其历史上规模最大的垃圾填埋场——下坪固体废弃物填埋场的‘清仓’工程。该填埋场自1997年启用以来，累计填埋垃圾超过2000万吨，曾是深圳处理城市生活垃圾的主要终端设施。随着城市环保标准提升和土地资源日益紧张，传统填埋方式已难以为继。为此，深圳启动‘清仓’行动，通过筛分、分类、资源化利用等技术手段，将陈腐垃圾进行无害化处理和再生利用。一方面，可回收物如塑料、金属被提取再利用；另一方面，有机质部分经处理后用于土壤改良或能源转化。整个项目预计耗时数年，完成后不仅释放大量宝贵土地资源，还将显著减少甲烷等温室气体排放，助力深圳实现‘双碳’目标。这一举措标志着深圳从‘末端填埋’向‘循环利用’转型迈出关键一步，也为全国其他超大城市提供可复制的固废治理样板。
Shenzhen is advancing a large-scale ‘stockpile clearance’ project at its largest landfill site—the Xiaping Solid Waste Landfill. Operational since 1997, the landfill has accumulated over 20 million tons of municipal solid waste and once served as the city’s primary terminal for garbage disposal. However, with rising environmental standards and increasing land scarcity, traditional landfilling is no longer sustainable. The city has therefore launched this clearance initiative, employing advanced techniques such as screening, sorting, and resource recovery to treat aged waste in an environmentally safe manner. Recoverable materials like plastics and metals are extracted for recycling, while organic fractions are processed for soil amendment or energy generation. The multi-year project is expected to free up significant urban land and substantially reduce greenhouse gas emissions—particularly methane—supporting Shenzhen’s carbon neutrality goals. This effort marks a pivotal shift from end-of-pipe landfilling toward a circular waste management model, offering a replicable blueprint for other megacities across China.
