WSU researchers are using a material found in crab shells to improve concrete and reduce carbon emissions.  The researchers plan to use chitin, which can be found in seafood shells, to create longer lasting concrete, said Michael Wolcott, research collaborator and WSU associate vice president for research. Chitin has strong components that provide strength and structural capacity, as seen in strong crab shells, said Somayeh Nassiri, research collaborator and WSU assistant professor. “That was an inspiration for us,” she said. “We can use [chitin] in the same way in construction materials because we also want to make them stronger.” Chitin is the second most abundant polymer in nature, Wolcott said. Chitin’s chemical structure forms tight crystals.
