alganexus.com Observed source
Editorial interest 78/100 Selection signal · not a rating of the site

AlgaNexus presents modular microalgae reactor tubes designed to capture CO₂ in buildings, transit sites, campuses, and public spaces.

Landing page captured for the 2026-08-29 issue.

Field notes

The installation is built around a repeatable reactor tube rather than a bespoke one-off structure: the page describes single units or larger arrays placed indoors, on facades, or in public settings. It reports 50 litres of capacity per standard tube and claims up to 5,500 kg of annual CO₂ removal, with IoT tracking intended to create an ongoing record for ESG reporting. Detailed technical information is available by request.
