Vom Phosphorrezyklat zum intelligenten langzeitverfügbaren Düngemittel - Forschungsprojekt gestartet

(PresseBox) (Würzburg, )
Phosphatdünger aus Klärschlammasche herzustellen ist Ziel des vom Bundesministerium für Ernährung und Landwirtschaft (BMEL) geförderten Forschungsprojektes PRiL. Dabei wird auf der Basis des biochemischen P-bac-Verfahrens rückgewonnene Phosphat zu einem marktfähigen Düngemittel weiterentwickelt. Ein besonderes Augenmerk liegt zudem auf der Wiederverwertbarkeit der im Verfahren entstehenden Reststoffe.

Phosphor ist ein elementarer Bestandteil allen Lebens: Menschliche, tierische und pflanzliche Organismen brauchen Phosphor, um existieren zu können, er ist Bestandteil der DNA.

In der Landwirtschaft werden großflächig phosphathaltige Düngemittel eingesetzt, um die Erträge sichern und steigern zu können. Rund 90 Prozent des heute abgebauten Phosphats werden zu Düngemitteln verarbeitet und landen so auf unseren jwktqu.
