Case

Measurement and mitigation of microplastics in stormwater and wastewater

In recent years, the Danish Technological Institute (DTI) has been a principal partner in several R&D projects focusing on characterisation and removal of microplastics and microrubber in wastewater treatment plant influent/effluent, industrial wastewater and stormwater, respectively.

Based on chemical sample purification and Raman-spectroscopy, DTI has developed a method enabling identification, characterisation and measurement of both microplastic and microrubber particles obtained from water samples. The method has been continuously applied, improved and further developed over the past five years. Focus has also been on the removal of microplastics from different water sources by developing and successfully demonstrating a variety of wastewater treatment technologies. The close collaboration with Danish universities, water utilities and water technology providers has provided important knowledge in terms of measuring and mitigating microplastic pollution in water environments. The projects have received funding from the Danish Eco-Innovation Programme (MUDP) and the Water Sector Development and Demonstration Programme (VUDP).
