Abstract

Se da a conocer un método para el tratamiento de lodo biológico (1), donde el lodo biológico comprende estructuras celulares. El método puede comprender mezclar el lodo biológico con un ácido (2) para obtener una mezcla (3); romper las estructuras celulares del lodo biológico en la mezcla al menos en forma parcial; y separar una fase sólida (4) a partir de la mezcla, obteniendo de esa forma un producto (5) que comprende la fase sólida. También se dan a conocer un producto (5) que comprende la fase sólida (4) que puede obtenerse mediante el método.
