Indoor Plant-Based CO₂ Sink with Energy Savings
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.
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 the 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.
