Waste interceptors are floating barriers placed in city rivers and canals to catch trash before it spreads. They help keep waterways clean, protect fish and plants, and make the water safer for everyone. These simple but smart devices work quietly, cost little, and fit well into the flow of water. By stopping litter early, they help build a cleaner, healthier city for today and the future. When people care and work together, these small helpers can make a big difference.
