CO₂ Biomanufacturing
Using the original technology from Professor Wei Huang's team at Oxford University, a new generation of green biomanufacturing platform is constructed with photovoltaic-driven artificial photosynthesis and bacterial bionanoreactors at its core. This platform directly synthesizes high-value products from CO₂, achieving integrated solutions for carbon-negative production, clean energy, and bio-based materials.
