In 2024, Shenzhen launched a landmark environmental remediation project: excavating and rehabilitating the Xiaping landfill, which had been sealed for nearly 20 years. Closed since 2005, this massive waste mound accumulated over 7 million tons of municipal solid waste and was once one of the largest landfills in southern China. Facing increasing pressure on urban land resources and stricter environmental standards, Shenzhen adopted an integrated approach—screening, resource recovery, and ecological restoration—to systematically treat the legacy waste. The project will recover recyclable materials such as plastics and metals, apply bio-stabilization and aerobic treatment technologies to reduce pollution risks, and ultimately transform the site into an ecological park or public green space. This initiative marks a significant shift in Chinese urban waste management—from end-of-pipe landfilling toward circular regeneration—and offers a replicable model for other cities grappling with historic waste sites. The project is expected to take 3 to 5 years and cost over RMB 1 billion, reflecting Shenzhen’s strong commitment to sustainable development and ecological civilization.
2024年，深圳启动了一项具有里程碑意义的环境治理工程——对封存近20年的下坪垃圾填埋场进行开挖整治。该垃圾山自2005年封场后一直处于封闭状态，累计填埋垃圾超过700万吨，曾是华南地区最大的生活垃圾填埋场之一。随着城市土地资源日益紧张和环保标准不断提升，深圳决定采用‘筛分—资源化—生态修复’的综合技术路径，对陈旧垃圾进行系统性处理。工程不仅将回收可利用材料（如塑料、金属等），还将通过生物稳定化和好氧处理技术降低污染物释放风险，并最终将原址改造为生态公园或公共绿地。这一举措标志着中国城市从‘末端填埋’向‘循环再生’转型的重要一步，也为全国其他城市处理历史遗留垃圾问题提供了可复制的经验。项目预计耗时3至5年，总投资超10亿元，体现了深圳在可持续发展与生态文明建设方面的坚定决心。
