Reusing CO2 for the sustainable development of several new technologies

Promising technologies to capture CO 2 from the atmosphere require major additional research to develop efficient and cost-effective techniques for large-scale operations. However, there could be other ways to help mitigate these issues: that is, by developing new technologies that use CO 2 as input to address other important environmental challenges. This work discusses such technologies that our group patented based on a long-term research program. The study highlights CO 2 's role as an input in sustainable solutions for water desalination, as a fire retardant, and water disinfection, challenging previous perceptions and opening avenues for further research. • Technologies that use CO 2 as an input to address important environmental issues. • Ion exchange resins regeneration using Bicarbonate ions from CO 2 gas for water desalination. • Hot CO 2 from combustion gases in bubble columns to sterilise and desalinate water. • CO 2 -saturated zeolite material as a new technology for fire suppression.
