# 2025 Hydrogen Production |
|
This technology converts food waste into clean biohydrogen through a co-culture of microalgae and activated sludge bacteria. In this closed-loop system, algae photosynthesise oxygen while bacteria consume it, creating the low-oxygen environment needed for efficient hydrogenase activity. Operating in photobioreactors, the system produces up to 1,600 mL/L of hydrogen, recovers 80–95% of nutrients, and sequesters CO₂. It also yields biofertiliser and reduces treatment costs, offering a scalable route to the circular bioeconomy and energy-efficient waste management
