Abstract	This work presents an IoT-based platform to enable a circular economy through waste recycling focus on logistics systems. The IoT platform allows connecting the waste picker and dispensers. The former is the user responsible for waste recycling, and the second is the user who generates the waste. The platform hardware comprises a selective collection bin equipped with microcontrollers, sensors, and communication modules. The hardware allows monitoring the bin filling level, reporting its longitude and latitude, and lock/unlock it. The user interface is a mobile application, which offers different access functions according to the user type. The waste picker has access to the city map containing the bins ready to be collected and can reserve them for a scheduled collection. The dispensers are encouraged to recycle based on a trash weight gamification approach. The MQTT (Message Queuing Telemetry Transport) protocol enables the platform entities to communicate through a broker server. © 2021 IEEE.
