Because I adore things like this.
"We could be producing #concrete that's 30 percent stronger by processing and adding charred #CoffeeGrounds to the mix, researchers in #Australia discovered."
Every year the world produces a staggering 10 billion kilograms (22 billion pounds) of #coffee #waste globally. Most ends up in #landfills."
This could be the answer to so many problems at once: how to dispose of #OrganicWaste / #FoodWaste, reduce contributions to #landfill sites (& the accompanying #GreenhouseGases produced as it decays), reduce the extraction of #sand from river beds & banks around the world, thus preserving our finite natural resources, and so much more.
"The researchers cautioned that they still need to assess the long term durability of their cement product. They're now working on testing how the hybrid coffee-cement performs under freeze/thaw cycles, water absorption, abrasions and many more stressors" - but still, it's exciting!
