Desarollo de un fertilizante N líquido a partir de un efluente agro-industrial

Abstract

La codigestión anaerobia del purín y otros residuos agroindustriales es uno de los tratamientos de residuos más utilizados en Europa, aunque su implantación en España y Portugal es muy escasa. El mayor beneficio de este tratamiento es la producción de metano y digestado, que se utiliza como fertilizante debido a su contenido en nitrógeno, fósforo y potasio. El objetivo de este trabajo ha sido utilizar la tecnología de membranas permeables a los gases para capturar el N del digestado de purín codigerido con residuos de piel de naranja, obteniendo una solución líquida de sulfato de amonio que se ha testado como fertilizante en ensayos en micromacetas. Los datos obtenidos muestran una recuperación del 62% del N del digestado, y una tasa de recuperación de N de 43.0 ± 6.6 g N por m2 de membrana y por día. Los resultados del ensayo en micromacetas muestran que solución líquida de sulfato de amonio tuvo un efecto fertilizante similar al de la fertilización con nitrógeno mineral.
