With a total fund of 8 million Swedish crown, Sahar Dalahmeh her collaborators will evaluate contribution of stormwater from roads in polluting the environment with microplastics and will investigate how to integrate green infrastructure into pollutant removal, by assessing the potential, efficiency and design of road-side filters (bark and biochar) for removing MP from stormwater, to function as planting sites and to retain water. The project comprises four work tasks: 1) To assess the composition, particle size and quantities of MP in stormwater from different urban sources; 2) to assess and compare the efficiency and potential of road-side filters made of biochar or bark filters in removing MP and in acting as green beds, and compare them with soil beds; 3) to develop a conceptual design for road-side green filters for MP removal; and 4) to assess their environmental sustainability in terms of e.g. climate change and water quality impacts. The project will be implemented within four years in collaboration with researchers from Aalborg University in Denmark and Malmö University
