IoT based waste management system use smart sensors and connected devices to monitor waste levels in real time. These systems optimize waste collection by notifying authorities when bins are full, reducing unnecessary trips and operational costs. Data analytics enable route optimization for garbage trucks, leading to lower fuel consumption and emissions. IoT also helps identify waste composition, promoting better recycling and resource management. With automation and remote monitoring, cities can maintain cleaner environments and improve sustainability. The technology offers a scalable solution for both urban and industrial waste management challenges.
