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 spaces to support citywide sustainability initiatives.

Office, transit site, campus, government building — if it has a wall, a lobby or a facade, it's worth a conversation.
