Freshwater ecosystems around the world are facing increasing challenges due to rising temperatures in urban areas, leading to the proliferation of invasive aquatic vegetation, among other consequences. This study focuses on the case of Elodea nuttallii in the river Po, Turin (Italy), where maual eradication has been identified as the most effective method of environmental control. However, this approach generates significant amounts of plant biomass that is currently treated as organic waste. To address this problem, this research investigates the potential of utilising aquatic plant biomass as a valuable raw material for the production of biobased materials to replace fossil-based plastics.
