The city of Portland, Oregon collected more waste in 2020 than any other year on record due to increased residential waste and a lack of recycling care during the pandemic. This has led to concerns about littering and the need for intelligent smart city solutions in waste management. The Dedalo Cities platform, built on CARTO, offers real-time management of waste, optimization of container filling and recycling, and route optimization using IoT data, aiming to reduce costs and environmental impact. By combining smart sensor information with a citizen app, the solution provides detailed insights into waste production, container inventory, and network status, enabling more efficient waste collection and minimizing negative effects on cities.
