The COVID-19 pandemic has increased public awareness of the effects of poor indoor air quality. The supply of fresh air in an enclosed indoor space can be very low or null. Also, CO₂ levels may reach health-threatening levels. Technologies to reduce atmospheric CO₂ and improve indoor air quality are important. The EU-funded MICRO-BIO project will develop a platform to capture CO2 from indoor air and transform it into valuable carbon-neutral commodity chemicals. For this purpose, it will design a CO₂ micro-concentrator module to adsorb CO2. It will also develop a real-control system for steering gas bio-electro-fermentation towards selective production of hexanol using the CO₂ captured from indoor air. Ultimately, the project will contribute to clean energy technologies.
