Aalborg has a major challenge with increased amounts of waste in the city as population growth increases. To a greater extent than now to recover waste in a circular economy, where waste is seen as a resource, it requires an increased sorting of waste. In addition, collection systems must be improved and made visible especially in the densely urban areas, where buried waste containers will be established in the coming years to replace containers in backyards etc. In order to ensure greater sorting among citizens, new solutions are needed. One of the solutions is sensors in waste containers, which can report filling levels to the operator who has to empty the container, but also information to citizens on how to sort the waste in the best possible way. The aim of the project is to reduce waste volumes and lead to better sorting of waste in cities. Through clusters and close collaboration with Aalborg University (AAU), the project will invite companies to enter into innovation partnerships with Aalborg Municipality and the university to develop and/or test technology that can contribute to additional solutions to the waste problem.The companies will contribute to solutions to specific challenges addressed in Aalborg Municipality’s holistic urban strategy.
