Scalable Electrochemical Concrete Fabrication and Closed‐Loop Recycling
Advanced Science, Volume 13, Issue 24, 27 April 2026.The electrochemical‐driven recycling strategy establishes a reversible concrete material flow by extracting Ca, Si, Al, and Fe from concrete waste and regenerating functional feedstocks. These reversed products are reassembled into new concrete, which re‐enters service and ultimately returns to waste, enabling a closed‐loop, waste‐origin, and low ...
