Transforming active landfill sites into beautiful spaces: Singapore's innovative approach
Singapore has found a unique solution to deal with its waste problem by transforming an active landfill site into a purpose-built island. The government connected two existing islands and built a seven-kilometer embankment to enclose part of the sea. They then filled these sections with ash from incinerated landfill waste, compacted it, and added soil to enable plant growth. The result is a thriving ecosystem that serves as both an active landfill site and a beautiful green space. By repurposing active landfills in this way, Singapore has not only addressed its space shortage but also created a sustainable and visually appealing solution.
