The research

To reach good environmental status as well as to use the Baltic Sea for fisheries these micro-pollutants and micro-plastics need to be removed. BONUS CLEANWATER aims at reducing the input of micro-pollutants and micro-plastic from wastewater into the Baltic Sea by exploring, developing and comparing new eco-technology approaches. The solutions will be developed in close collabora-tion with the end-users.

BONUS CLEANWATER addresses the three current problems:
1. The lack of knowledge on micro-pollutants and micro-plastic, on pollution loads into the Baltic Sea for which pollutants wastewater effluents or stormwater are the relevant sources.
2. The lack of energy efficient and eco-technology based treatment systems to remove micro-pollutants and micro-plastic from sewage and stormwater (combined sewer overflow – CSO – and rain runoff).
3. The lack of cost-efficient high frequency testing methods for micro-pollutants and high validity testing for micro-plastic particles.

The BONUS CLEANWATER project is a multi-disciplinary and interdisciplinary research effort integrating the following core disciplines: natural science, technology and engineering, finance (cost effectiveness) and environmental performance assessment by use of life cycle assessment of the reference and CLEANWATER eco-technologies.
