Australian researchers transform coffee waste into stronger, sustainable concrete
Australian scientists have discovered a novel way to divert used coffee grounds from landfills by transforming them into a material that strengthens concrete by up to 30%. The process involves heating the coffee grounds in a low-oxygen environment to create biochar, a carbon-rich substance that integrates seamlessly into concrete production. This innovation addresses the global challenge of managing 10 billion kilograms of coffee waste produced annually, reducing greenhouse gas emissions and reliance on natural resources like sand. By promoting upcycling and waste diversion, this breakthrough supports a circular economy and advances sustainable construction practices. Further research is underway to evaluate the material’s long-term performance under different environmental conditions. Learn more about the findings.
