Alganexus grows living microalgae inside modular reactor tubes that fit into buildings, transit sites and public spaces. Each tube removes CO₂ through photosynthesis and reports what it removed, in real time.
Every deployment is built from the same core reactor tube — indoors or on a facade, single unit or full installation.
| System capacity | 50L per standard tube |
| Annual CO₂ removal | Up to 5,500 kg per tube |
| Power source | Grid, solar-optional (carbon-negative operation) |
| Monitoring | IoT-enabled carbon tracking |
| IP status | Patent protected |
Process detail stays under NDA. Growth parameters, biomass conversion methods and patent documentation are shared once we're in a real deployment conversation — not published here.
The same modular system, installed to support ESG goals across very different environments.
Schools and universities use the system for carbon reduction, and as a hands-on tool for environmental science.
Businesses integrate the reactors into their workspaces, improving indoor air quality and strengthening ESG reporting.
Installed in public sector buildings to support departmental sustainability initiatives.
