Abstrakt: This review focuses on the alternative uses of Elodea nuttallii (Planch.) H.St.John biomass. Elodea nuttallii is as an aquatic invasive alien species classified in the EU as a Species of Union Concern. Its dense monospecific stands affect both aquatic ecosystems and human activities, thereby requiring specific monitoring and management measures. The handling of E. nuttallii has a high economic cost, and the biomass removed from natural environments is considered a mere waste product. The need to implement circular economy, reducing waste and preserving natural capital, has led to the research for the reuse and valorisation of waterweed biomasses, such as E. nuttallii. This review critically assesses the feasibility and potential applications of E. nuttallii biomass in various sectors, including bioenergy production, extraction of metabolites, and fertilization. Out of more than 200 articles from 1965 to 2023, only 16 were found to deal with the use of harvested biomass, all within the last 12 years. This review highlights that the valorisation of E. nuttallii biomass is an underrepresented topic in scientific literature, and therefore in industrial sectors. Studies on biogas production are the most represented and have shown that E. nuttallii chemical composition is suitable for energy production, but is better suited as an additional feedstock to other biomasses already used for this purpose. New more cost-effective applications, such as animal feed and biosorbent, should be further addressed. By investigating alternative uses for E. nuttallii biomass, this review contributes to the development of sustainable practices that would turn a costly waste into a valuable resource.
