El manejo de residuos sólidos se ha configurado en una temática relevante y de creciente interés en la comunidad científica interesada en este tópico, dado que es de conocimiento público la dificultad que comporta su manejo y tratamiento, que generan daños complejos al medio ambiente. Este trabajo tiene el objetivo de analizar el proceso de digestión anaeróbica de residuos sólidos urbanos de Manta, desde la asunción del método dialéctico. Entre los resultados destaca que: El proceso de digestión anaerobia en fases separadas es un esquema novedoso que mantiene dos reactores en serie, en los que se llevan a cabo las fases de acidogénesis y metanogénesis, respectivamente. Del análisis realizado, se confirma que una de las posibles alternativas de respuesta para disminuir el problema en la fracción orgánica de los RSU es el hallazgo de un procedimiento energético, a través de su tratamiento por biogás. Palabras clave: Residuos sólidos urbanos; digestión anaeróbica; fases separadas, método dialéctico.

From the analysis carried out, it is confirmed that one of the possible response alternatives to reduce the problem in the organic fraction of MSW is the discovery of an energy procedure, through its treatment by biogas.
