Recovering
valuable resources
from seawater brines
MagNa is a research project co-funded by the European Commission that will develop a system to recover valuable raw materials from seawater brines with the goal of reducing Europe’s reliance on imports.
A circular-economy approach to give value to seawater brines
Seawater desalination is an increasingly used method to obtain water for industrial use, but this process generates brines—effluents with a high concentration of salts—which have traditionally been considered waste. The MagNa project will give value to these brines by recovering high-purity magnesium hydroxide and sodium chloride (salt) through a novel technology.
Magnesium and sodium are valuable raw materials with applications in various industries such as chemicals and pharmaceuticals, and they are currently imported in large quantities from countries outside the European Union (EU). Thanks to MagNa, this dependency will be reduced, while at the same time minimising the environmental impact of desalination through a circular-economy approach.
