Description du projet
Boucler le cycle du phosphore
Le phosphore (P) est un nutriment essentiel en agriculture, mais les ressources de phosphore exploitable sont limitées, et l’exploitation de ses minerais a perturbé les cycles mondiaux. De plus, le flux de phosphore des zones agricoles aux eaux de surface contribue à l’eutrophisation, un surenrichissement des écosystèmes aquatiques par des nutriments menant à une croissance accélérée des algues, à une perte de la biodiversité et à d’autres effets négatifs. Avec le soutien du programme Actions Marie Skłodowska-Curie, le projet P-TRAP développera de nouvelles approches pour piéger le phosphore dans les zones agricoles drainées et dans les sédiments des lacs eutrophiques. Ces approches reposent sur l’utilisation de sous-produits contenant du fer issus du traitement de l’eau. Les minéraux de fer chargés en phosphore seront convertis en engrais en vue de parvenir à une économie circulaire durable tout en diminuant l’impact environnemental.
Objectif
Flux of phosphate (P) from agricultural areas to surface waters is wasting a resource which is becoming scarce and is in conflict with the principles of a circular economy. Enhanced loading of surface water with P is the main cause for eutrophication and presents a key challenge in meeting the objectives of the EU Water Framework Directive. P-TRAP targets both problems and develops new methods and approaches to trap P in drained agricultural areas and in the sediments of eutrophic lakes. Trapping of P involves the application of iron(Fe)-containing by-products from drinking water treatment. P-TRAP aspires the ideas of a circular economy and aims at recovering the retained P in agricultural systems. Novel microbial technologies will be developed to convert P-loaded Fe-minerals into marketable fertilizers whose suitability will be evaluated. The new P-TRAP technologies have in common that they rely on the naturally strong connection between P and Fe and the innovative P-TRAP strategies will be underpinned by process-orientated investigations on the behavior of P during the transformation of Fe minerals. The latter are key in trapping and recycling of P in agricultural systems and lakes. P-TRAP establishes a framework of partners from multiple science and engineering disciplines. Integration of non-academic partners from various stakeholder groups into the P-TRAP consortium paves the way for direct implementation of the acquired knowledge. P-TRAP provides Early Stage Researchers (ESRs) an environment for conducting innovative scientific research by using state-of-the-art methodology. Training through P-TRAP increases the ESRs’ mobility between sectors, cultures, and nations and strengthens their responsibility to exploiting scientific results for societal and economical benefit. P-TRAP will offer ESRs an excellent starting point for a career of leadership in a number of environmental and sustainable business sectors, academia, and public administration.
