Water is becoming increasingly prominent as a source of all kinds of precious substances such as lithium, phosphorus, nitrogen and potassium. Lithium is especially important. This substance is used in the production of batteries. An international group of scientists from, among others, the Wetsus research institute in Leeuwarden and Wageningen University & Research (WUR) have been researching a technique that makes it possible to fish out various substances from the water separately from each other.
