Singaporean scientists convert shrimp shell waste into carbon-negative hydrogen fuel

Singaporean scientists have developed a method to convert shrimp shell waste into carbon-negative hydrogen fuel. The process also yields protein for aquaculture feed and calcium carbonate, aiming to capture more carbon dioxide than it emits. Researchers are exploring commercial applications, though scaling remains a challenge. This technology offers a dual solution for waste reduction and cleaner energy, with potential applications beyond seafood waste for various biomass types.
