The present invention describes a system for recovering nutrients from urine, aimed at adsorbing phosphorus and urea. Human urine contains nutrients that are essential for agriculture, such as nitrogen (N), phosphorus (P) and potassium (K), which are considered to be potential fertilizers. According to the proposed technology, the nutrient-recovery system consists of a single component made from plastic and intended to be attached inside urinals and toilet bowls by means of suction cups on the back thereof. Once attached, the component is strategically positioned, thereby enabling adsorption of the elements contained in the urine. To this end, the body includes a screw-in refill containing adsorbent material that is capable of recovering phosphorus and urea. The object of the invention is aimed at directly recycling phosphate and urea found in urine from urinals and toilet bowls by inserting and removing cartridges in a practical and simple manner. La présente invention concerne un système de capture de nutriments d'urine, destiné à l'adsorption de phosphore et d'urée. L'urine humaine contient des nutriments essentiels pour l'agriculture, tels que de l'azote (N), du phosphore (P) et du potassium (K), considérés comme des fertilisants en puissance. Selon la technologie proposée, l'élément de capture de nutriments consiste en une pièce unique fabriquée en plastique, à fixer à l'intérieur d'urinoirs et de cuvettes de W.-C. au moyen de ventouses situées sur sa partie arrière. Une fois fixée, la pièc est positionnée de manière stratégique, permettant ainsi l'adsorption des éléments contenus dans l'urine. À cet effet, le corps comprend un réservoir fileté contenant la matière adsorbante capable de capturer le phosphore et l'urée. L'invention a pour objet la réutilisation du phosphate et de l'urée présents dans l'urine directement dans les urinoirs et les cuvettes de W.-C., par insertion et retrait des cartouches de manière pratique et simple. A presente invenção descreve um sistema capturador de nutrientes de urina, que visa à adsorção de fósforo e ureia. A urina humana contém nutrientes essenciais à agricultura, tais como Nitrogénio (N), Fósforo (P) e Potássio (K), considerados fertilizantes em potencial. De acordo com a tecnologia proposta, o capturador de nutrientes consiste em uma peça única confeccionada em plástico a ser fixada dentro de mictórios e vasos sanitários por meio de ventosas em sua parte traseira. Uma vez afixada, a peça será posicionada de forma estratégica, possibilitando assim a adsorção dos elementos contidos na urina. Para tal, o corpo inclui um refll rosqueado que contém material adsorvente capaz de capturar fósforo e ureia. O objeto da invenção destina-se ao reaproveitamento de fosfato e ureia presentes na urina diretamente em mictórios e vasos sanitários, através da inserção e retirada dos cartuchos de forma prática e simples.
