Alganexus microalgae reactor tubes installed on an outdoor facade wall

Carbon capture, installed like equipment and monitored like one too.

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.

The system

One modular unit. Built to scale, not to be reinvented.

Every deployment is built from the same core reactor tube — indoors or on a facade, single unit or full installation.

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.

Where it's installed

Adopted across government, corporate and education.

The same modular system, installed to support ESG goals across very different environments.

Forest in the Library, an educational public installation

Educational Institutions

Schools and universities use the system for carbon reduction, and as a hands-on tool for environmental science.

Corporate office lobby installation

Corporate Offices

Businesses integrate the reactors into their workspaces, improving indoor air quality and strengthening ESG reporting.

Government building lobby installation

Government Installations

Installed in public sector buildings to support departmental sustainability initiatives.

Deeper technical detail is available on request. Deployment specs, verified performance data and case studies go out once we know it's a real conversation. That's a deliberate choice, not a delay tactic.
