Microbial fuel cells lead adoption because they offer the most direct path to energy recovery from organic wastewater. Industrial facilities with high-strength effluent, particularly in food processing and brewing, are early adopters. The real scaling opportunity is in municipal wastewater, where energy costs represent a significant share of operating budgets. Companies that can demonstrate reliable performance at pilot scale and offer modular, low-maintenance configurations are best positioned to capture procurement from utilities evaluating alternatives to conventional activated sludge systems.'
