Description du projet
Une alternative durable pour la récupération du phosphore
Le phosphore est un nutriment vital pour la croissance des plantes. La majeure partie du phosphore utilisé provient des roches phosphatées, une ressource limitée formée sur des millions d’années dans l’écorce terrestre. La récupération du phosphore des boues d’épuration constitue une alternative prometteuse. Financé dans le cadre du programme Actions Marie Skłodowska-Curie, le projet RECaPHOS travaille sur une nouvelle méthode de récupération du phosphore par la réaction thermochimique des boues d’épuration. Le projet entend optimiser et évaluer la nouvelle méthode et proposer des règles et des données pour une mise à l’échelle réussie. Il utilisera des modèles avancés pour étudier le processus thermodynamique et chimique en jeu. Des données expérimentales provenant des installations et de la documentation étayeront ces modèles.
Objectif
Phosphorus (P) is an essential nutrient and major economic factor. The EU covers its demands by importing Phosphate rock listed as critical raw material due to its scarce resource. Sewage sludge from waste water treatment plants is a promising alternative source of P. RECaPhos focuses on development of a novel method for phosphorus recovery based on the thermo-chemical reaction of sewage sludge, in the presence of CaO in a fluidized-bed reactor, assuring in the same time the destroy of dangerous pathogens, antibiotics and contaminations. Goal is to develop, optimize, and evaluate the novel method and to provide rules and data for process up scaling purposes. This will be achieved by means of development of innovative models to investigate the thermodynamic and chemical process taking place. Experimental data from host institution facilities and data from literature will be used for models validation and optimization. The results will be used as a basis for the design of a demo plant as well as for the identification/evaluation of the process economics and commercialization potential. Two reference cases will be studied, one for a new plant and one for a retrofit of an existing fluidized bed combustion plant. Comparison with other competitive processes will be realized. RECaPHOS is original, highly innovative, and ambitious since the same cheap widely available, natural, non toxic, and environmental friendly Ca-based material is used for P adsorption and subsequent P recycling as it is directly used as feedstock for fertilizer production, closing a natural cycle. RECaPHOS is an excellent and unique opportunity for the researcher who is a mother of two daughters to restart her career after more than 4 years of career break prior to call deadline due to maternity and after resettling back to Europe/Germany after a 3 years continuous stay outside Europe in the last 5 years, in a highly innovative non-profit academic institution that supports women and work life balance.
