AlgaNexus® modular reactor tubes house living microalgae that absorb CO₂ and deliver real time performance insights across built environments. Empowering cities and organisations to meet their climate goals.
Custom configured from the same core reactor tube to deliver reliable, scalable carbon capture performance across buildings, public spaces and city infrastructure.
| 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 |
Independently verified. Performance figures are verified by CMA Testing Hong Kong; the system was developed in collaboration with the Nano and Advanced Materials Institute (NAMI).
Every claim is backed by verified data — not just marketing.
A modular system built to advance sustainable ambitions and ESG objectives everywhere it's installed.
Schools and universities become early adopters of climate tech leadership. By bringing real time carbon capture into learning environments, they equip future innovators with firsthand experience of the technologies that will define tomorrow's sustainable cities.
Forward-thinking organisations integrate the system into their workplaces as a visible commitment to climate leadership. Each installation turns offices into intelligent, sustainability-enabled environments — reinforcing ESG strategy, elevating brand credibility, and signalling a long-term vision for responsible growth.
Across urban spaces, the system becomes part of a city's sustainability infrastructure. Families, commuters, and communities encounter living technology that captures carbon where life happens, demonstrating how future-ready cities can embed climate action seamlessly into everyday environments.
Watch how our modular reactor system operates across diverse installations that reflect our commitment to measurable climate impact.
