Semakau Island might be a landfill, but it’s no ordinary dump. Opened in 1999, it’s the world’s first offshore landfill—built between Pulau Semakau and Pulau Sakeng with a rock wall enclosing part of the sea to hold incinerated waste. Here’s the twist: it’s amazingly clean. So clean, in fact, that people go there for nature walks, birdwatching, and even stargazing. Thanks to NEA and nature groups, the surrounding mangroves, coral reefs, and marine life have been carefully preserved. Semakau proves that smart waste management and environmental care can go hand in hand. It’s a landfill—but make it eco-friendly.
