Revolutionary Reactors Turn CO2 Into Valuable Minerals With Fly Ash

Researchers have innovated reactors that use fly ash to effectively mineralize CO2, presenting a sustainable approach to reducing greenhouse gas emissions and advancing global climate goals.
In a significant advancement in sustainable waste management and CO2 sequestration, researchers have developed reactors that use fly ash particles to mineralize carbon dioxide. This innovative method promises a sustainable and enduring solution to the critical problem of greenhouse gas emissions while repurposing an industrial by-product.

The relentless march of industrialization has corresponded with a surge in CO2 emissions, a key driver of global warming. Existing carbon capture, utilization, and storage (CCUS) technologies grapple with issues of efficiency and cost. Fly ash, a coal combustion by-product, offers a promising avenue for CO2 mineralization, turning waste into a resource and curtailing emissions. Yet, prevailing reactor designs struggle to achieve the desired synergy between gas-particle interactions and operational efficacy. These hurdles underscore the imperative for an in-depth investigation into innovative reactor configurations and operational fine-tuning.
