The Internet of Things (IoT) already became an enabling technology in many areas. In Smart Waste Management (SWM) systems, IoT helps to interconnect such loosely coupled components as garbage containers, sensors, trucks, cloud services, recycling factories and devices of citizens. We discuss our approach for managing physical infrastruc-ture and software components which form an SWM system and enable its interaction with other Smart City services and applications. We described an architecture of intercon-nection between sensors and cloud through the LoRaWAN protocol and usage of that information by external system.
