In Singapore, shopping malls are turning waste into a resource by reusing condensation from their air-conditioning systems. Instead of letting this water go to waste, it’s collected, filtered, and used to irrigate plants inside and around the malls. This creates a smart cycle where cooling the air also sustains greenery, cutting down on the need for extra freshwater.
The system captures droplets forming on the cooling coils of air conditioners, which in Singapore’s humid climate can generate large amounts of water each day. By directing this into storage tanks, malls keep indoor gardens, rooftop plants, and surrounding landscapes thriving without heavily relying on municipal water supplies.
This approach not only saves water but also boosts sustainability in a city where resources are limited. It’s a simple yet effective example of how urban spaces can merge technology with eco-friendly practices, turning air-conditioning from an environmental burden into part of a greener solution.
