Scientists Discovered An Amazing Practical Use For World’s Leftover Coffee Grounds
We could be producing concrete that’s 30 percent stronger by processing and adding charred coffee grounds to the mix, researchers in Australia discovered. Their clever recipe could solve multiple problems at the same time.
Every year the world produces a staggering 10 billion kilograms (22 billion pounds) of coffee waste globally. Most ends up in landfills.
“The disposal of organic waste poses an environmental challenge as it emits large amounts of greenhouse gases including methane and carbon dioxide, which contribute to climate change,” explained RMIT University engineer Rajeev Roychand when the research was published in 2023.
