Abstract[English]
Solid waste management is a pressing environmental issue due to rapid urbanization and population growth. Researchers are turning to organic farming as a solution to resource depletion. Disposing of sewage sludge can lead to environmental degradation and the spread of diseases. Developing a cost-effective phosphate fertilizer from sewage sludge would benefit water and sewage companies, as well as farmers and agricultural companies. Producing a low-cost phosphate fertilizer from sewage sludge with sonoleaching method, could address environmental pollution and provide economic benefits.[French]
La gestion des déchets solides est un problème environnemental urgent en raison de l'urbanisation et de la croissance démographique rapides. Les chercheurs se tournent vers l'agriculture biologique comme solution à l'épuisement des ressources. L'élimination des boues d'épuration peut entraîner une dégradation de l'environnement et la propagation de maladies. La mise au point d'un engrais phosphaté rentable à partir de boues d'épuration serait bénéfique pour les entreprises de traitement de l'eau et des eaux usées, ainsi que pour les agriculteurs et les entreprises agricoles. La production d'un engrais phosphaté à faible coût à partir de boues d'épuration grâce au procédé de lixiviation par ultrasons pourrait permettre de lutter contre la pollution environnementale et fournir des avantages économiques.
