First-year high school students from La Salle Girona have visited the laboratory of the Environmental Physics Group. During the visit, they had the opportunity to learn firsthand about the research the group is conducting on the transport of microplastics in coastal and wetland areas as part of the PlastikHum project (https://www.udg.edu/ca/projectes/plastikhum).They discovered the different types of plastics, the challenges of recycling them, and how they can be found in various products such as cosmetics, clothing, and packaging—causing significant harm to the natural environment. Therefore, they realized the importance of following the three Rs: Reduce, Reuse, and Recycle.
