Mobility & logistics


We will have a special track dedicated to Mobility and Logistics. This track will address the question of how sustainable mobility of people and goods should be designed, and will explore existing approaches. Topics covered will include battery recycling, circular public transportation, and cradle cars, among others. We will take a closer look at these ideas to provide answers to this critical issue.
