A Novel Algae Synergy for Carbon Capture and Water Purification
CWSF · 2026 Environment & Climate Change
Overview
This project explores a new way to boost algae so it can clean polluted water and capture carbon much faster. I built 32 mini bioreactors and experimented with Chlorella vulgaris by adding graphene quantum dots (GQDs) and natural polysaccharides like alginate and chitosan. GQDs help algae absorb more light, while the polysaccharides can feed the cells and bind pollutants. Each day, I measured nitrate levels, growth, and biomass production using a custom image‑analysis system. The results were clear: the combination of alginate + GQDs created a powerful synergy. These cultures grew the fastest, produced the most biomass, and removed pollutants far more effectively, nearly doubling performance compared to other treatments. This discovery shows that pairing a carbon‑rich biopolymer with a light‑enhancing nanomaterial can dramatically improve algae’s environmental power, offering a promising path for cleaner water and stronger carbon capture. A brand new approach at solving the worlds most pressing issues.
