The annual production of 10 billion kilograms of coffee waste globally poses a significant environmental concern, with most of it ending up in landfills and contributing to greenhouse gas emissions. Concurrently, the construction sector faces a surge in demand for concrete, a material known for its substantial environmental impact. The innovative approach developed by the RMIT research team involves converting coffee grounds into a potent additive through a process called pyrolysis, which entails heating the waste to over 350°C in an oxygen-free environment to produce a carbon-rich biochar that can be integrated into the cement matrix.
