Abstract Achieving international climate goals will likely require large-scale removal of carbon dioxide from the atmosphere 1. A promising means (CDR) is by enhanced weathering and carbonation various alkaline industrial wastes such as slags ash 2,3. Although global potential has been estimated 4–7, magnitude uptake natural these worldwide remains uncertain. Here, using results more than a decade experiments an extensive dataset activity waste disposal, we show that annual 0.43 Gt CO2 (95% CI: 0.33–0.53 CO2) in 2020, increasing at average rate 2% per year for past decade. Between 1930 estimate have absorbed 14.0 11.2–25.2 carbonation. Our reveal extent to which represent unaccounted sink cycle, also highlight opportunities enhancing future.

The chemical industry faces major challenges despite recent progress in the transition to more environmentally friendly processes. Sustainable industrial chemistry relies on optimization of protocols and downstream processes such as extraction, purification, drying. Process intensification, which includes non-conventional techniques continuous manufacturing, has emerged a key strategy improve efficiency environmental impact. Technologies ultrasound, microwaves, mechanochemistry, reactive extrusion offer improved performance but face scalability proprietary barriers. Flow offers additional benefits, including smaller reactors, lower energy consumption (from 40 90%), increased safety through continuous, automated reactions. However, implementing these methods requires overcoming engineering, economic, regulatory hurdles. Biphasic catalysis sonochemical activation liquid–liquid systems are promising approaches for scalable reactions under mild conditions. pharmaceutical industry, source waste, shown resistance due high validation costs complex regulations. Fortunately, international institutions have introduced programs facilitate introduction advanced technologies. Future perspectives emphasize integration modular, intensified with digitalization smart manufacturing. Collaborative, transdisciplinary research will be crucial accelerating commercialization addressing sustainability production.
