This compact, energy-efficient system enables decentralised carbon capture directly within buildings. Each unit removes 30–60 tonnes of CO₂ per year, using waste airflow and heat to cut energy use by up to 90% compared to conventional DAC. Compatible with evolving sorbent technologies, it reduces Scope 1 and 2 emissions and supplies local CO₂ for industrial use. The modular design offers a scalable, cost-effective solution to help cities and businesses meet their net-zero targets
