Two‐Stage Anaerobic Digestion of Sugarcane Vinasse: A Bibliometric Analysis of Research Trends and Gaps

Environmental Quality Management, Volume 36, Issue 3, September 2026.
ABSTRACT Sugarcane vinasse, a by‐product of bioethanol production, poses a significant environmental challenge due to its high organic load and the large volumes generated. Anaerobic digestion (AD) has been widely explored as an alternative treatment, particularly in two‐stage configurations that can enhance methane recovery.
