Technology Overview

This solution redefines carbon management in buildings by embedding a functional carbon sink within the interior environment. Through the strategic integration of modular indoor plant systems, this technology enables real-time CO₂ absorption via photosynthesis. It is designed to address the dual challenge of poor indoor air quality and energy-intensive mechanical ventilation in dense urban buildings.

The system introduces an easy configuration that channels CO₂-rich return air into designated plant zones—either within enclosed chambers or openly integrated within the space—forming a biofiltration loop. This indoor carbon sink operates passively, requiring minimal infrastructure modification.

Technology Features

• CO₂ absorption of approximately 80 ppm over 8 hours in occupied zones

• Energy savings from reduced air intake

• Estimated payback periods of 2 to 4 years for retrofitted solution

• Controlled or open-air plant setups adaptable to existing layouts

• Minimal infrastructure needs for open system configuration

Potential Applications

• Retrofitting office buildings

• Indoor urban farming

• Co-working spaces, classrooms, and public indoor zones

• Integration with HVAC systems for sustainable buildings

Benefits

• Reduction of ventilation energy use and operational heating, ventilation and air conditioning (HVAC) costs

• Passive CO₂ absorption via photosynthesis without occupant disruption

• Modular design adaptable to brownfield sites

• Support health, productivity, and green certification goals

Commercialisation

• This technology is available for licensing and technology transfer.
