La digestión anaerobia es un proceso de degradación biológica que consta de cuatro etapas (hidrólisis, acidogénesis, acetogénesis y metanogénesis) y tiene como finalidad convertir la materia orgánica en biogás, biosol y biol por medio de una serie de reacciones bioquímicas. La tecnología de degradación anaerobia ha sido empleada en la remediación de efluentes provenientes de la industria del café instantáneo, con el propósito de reducir su alta carga contaminante. Por lo tanto, el objetivo del presente trabajo es compilar información referente al peligro que ocasionan las aguas residuales de la industria del café instantáneo, así como las tecnologías de remediación para mitigar el impacto ambiental que estas generan al medio ambiente y a la salud del ser humano. Se revisan las diferentes alternativas tecnológicas, denotando que la digestión anaerobia, aplicada bajo parámetros óptimos de operación permite degradar altos niveles de materia orgánica presente en el agua residual.
