The 2nd Progress meeting of NanOER Erasmus+ project was held today in a hybrid form at Chalmers University of Technology in Göteborg, Sweden. NanOER is a groundbreaking educational platform dedicated to the in-depth exploration of Life Cycle Analysis (LCA) in the context of nanoparticle treatments. Our mission is to shed light on the environmental aspects of nanomaterials, with a particular focus on their role in the construction industry, offering a unique perspective on the sustainability and broader consequences of these materials.
