Methane production from sugarcane vinasse: The alkalinizing potential of fermentative-sulfidogenic processes in two-stage anaerobic digestion

Researchers from the University of São Paulo have developed an innovative two-stage anaerobic digestion process that enhances methane production from sugarcane vinasse. Their approach, which integrates a fermentative-sulfidogenic stage, boosts biogas quality, lowers costs, and eliminates the need for chemical additives. This promising solution could revolutionize bioenergy recovery in sugarcane biorefineries.
