Shanghai's Houtan Park transforms industrial wasteland into urban wetland purifier

Shanghai's Houtan Park is a former contaminated industrial site that has been converted into a functioning wetland ecosystem. The park purifies river water on a daily basis through its natural design and processes. Recycled materials were incorporated into the project, reflecting local heritage and minimizing waste. Ecologically, the park contributes to carbon sequestration and supports the recovery of local wildlife. It also serves as a model for managing urban flooding while providing green communal spaces for residents.
