Plastic Plants

Summary Water hyacinths are invasive free-floating aquatic plants abundant in most tropical rivers. They grow rapidly in biomass, and expand in patches of tens of meters in diameter. Hyacinths have been found to entangle macroplastics. This project further investigates the role of hyacinths on riverine plastic transport. Further reading Schreyers et al. (2021), Plastic plants:…

Breaking the Urban Plastic-Flood Nexus

Summary The main goal of this project is to observe, understand and reduce the impact of plastic waste on urban flooding. To achieve this, three steps are defined. First, advanced technologies will be used to provide reliable and frequent observations of urban rainfall and plastic waste. Second, new data will be used to develop an…
