Capturing the Signal of Reactive Oxygen Species in Anaerobic Digestion Process and their Downstream Role: A Worthy Endeavor

emissions, including mechanistic insights and long-term environmental implications. Our findings suggest that the potential greenhouse gas flux from digestate due to ROS-related processes warrants serious attention. Overall, this review aims to advance the understanding of ROS in anaerobic digestion and support the optimization of both AD performance and its downstream ecological impacts.
