While trees are dressing up with new leaves and flowers are blossoming to create beautiful weaves of color on the horizon, the students of the Circular Material Hub are entering their final stage of their Thesis Lab experience. Spring is the time of growth. The students are experiencing growth, too. Healthy growth, with limits. To that end, the students of this Thesis Lab are researching the idea of creating a Circular Building Materials and (re)Manufacturing Hub to improve opportunities for circular construction in the region of South-Holland. The last months were characterized by hard work and wonderful moments of sharing. In this newsletter, we would like to share some of the experiences we had with the thesis lab, and provide an update with how the students are doing at the moment.
