El grupo de investigaci\u00f3n e-PLASCOM de la Universitat Polit\u00e8cnica de Catalunya – BarcelonaTech (UPC) desarrolla una soluci\u00f3n basada en aerogeles biodegradables de alginato de sodio y gelatina para la purificaci\u00f3n de agua no potable y la desalinizaci\u00f3n mediante energ\u00eda solar.<\/h4>

El acceso al agua dulce es uno de los grandes retos globales, especialmente en territorios afectados por la escasez h\u00eddrica, la contaminaci\u00f3n de recursos naturales o la falta de infraestructuras energ\u00e9ticas y de tratamiento. En este contexto, se necesitan tecnolog\u00edas m\u00e1s sostenibles, eficientes y asequibles, capaces de funcionar con fuentes renovables y de reducir la dependencia de procesos intensivos en energ\u00eda.<\/p>

El proyecto responde a este desaf\u00edo con el desarrollo de aerogeles, materiales ultraligeros con una estructura altamente porosa, fabricados a partir de biopol\u00edmeros naturales como el alginato de sodio y la gelatina. Estos materiales destacan por su hidrofilia, biodegradabilidad y bajo coste, lo que los convierte en una alternativa atractiva para aplicaciones ambientales vinculadas al tratamiento de agua.<\/p>

La soluci\u00f3n se basa en la t\u00e9cnica de congelaci\u00f3n direccional, que permite generar una estructura porosa orientada verticalmente. Esta arquitectura interna favorece el transporte r\u00e1pido del agua hacia la superficie por capilaridad: los canales verticales act\u00faan como microbombas que facilitan el movimiento del l\u00edquido dentro del material. De este modo, el agua llega de forma continua a la zona activa de evaporaci\u00f3n.<\/p>

Para incrementar la eficiencia del dispositivo, se incorpora negro de carbono, un agente fotot\u00e9rmico de bajo coste con una elevada capacidad de absorci\u00f3n de radiaci\u00f3n en una banda amplia del espectro solar. Este componente transforma la radiaci\u00f3n solar en energ\u00eda t\u00e9rmica y permite una evaporaci\u00f3n interfacial r\u00e1pida, sin necesidad de calentar toda la masa de agua. Esta gesti\u00f3n t\u00e9rmica, combinada con la baja conductividad propia del aerogel, reduce las p\u00e9rdidas de energ\u00eda hacia el agua subyacente y optimiza el rendimiento global del sistema.<\/p>

Adem\u00e1s de facilitar la purificaci\u00f3n por evaporaci\u00f3n solar, los aerogeles desarrollados presentan capacidad de adsorci\u00f3n de contaminantes gracias a los grupos funcionales presentes en los pol\u00edmeros. Esto ampl\u00eda el potencial de la tecnolog\u00eda en el tratamiento de aguas no potables, ya que combina evaporaci\u00f3n eficiente, uso de materiales naturales y posibilidad de capturar determinados contaminantes.<\/p>

La aportaci\u00f3n del e-PLASCOM se centra en el dise\u00f1o, fabricaci\u00f3n y optimizaci\u00f3n de estos aerogeles de biopol\u00edmeros, as\u00ed como en la integraci\u00f3n del componente fotot\u00e9rmico para mejorar su comportamiento bajo radiaci\u00f3n solar. El resultado es una tecnolog\u00eda con potencial de aplicaci\u00f3n en sistemas de purificaci\u00f3n descentralizados, especialmente en entornos donde se requieren soluciones de bajo coste, bajo impacto ambiental y funcionamiento aut\u00f3nomo con energ\u00eda renovable.<\/p>

Presupuesto y consorcio<\/h4>

El proyecto se desarrollar\u00e1 entre 2026 y 2028 y en \u00e9l participa tambi\u00e9n la Universidad de Tiangon (China). El presupuesto total es de 20.000 \u20ac.<\/p>
