A team of researchers from the University of East London (UEL) has found an unexpected solution to one of the construction industry’s biggest carbon problems—and it lies on the shoreline. New findings show that discarded seashells, typically treated as waste, can be transformed into a low-carbon concrete ingredient, potentially cutting significant amounts of CO₂ from one of the world’s most polluting materials and helping drive more sustainable construction.
