  2. CW: bodily fluid - nitrogen source

    Am looking at adding #CoffeeGrounds to my #Compost.

    I've seen a 20:1 carbon:nitrogen figure.
    Which is about lawn clippings.
    And so more nitrogen would help.

    Which is where urine would come in.
    Not turning up on the search engines.

    I know that urine is a popular #CompostActivator among the au fai.

    But wondering if anyone else has tried specifically urine + coffee grounds.

    I'm also getting great fungus growing on the cakes. Maybe let that work and then compost?

  3. Scientists Discovered An Amazing Practical Use For Our Leftover #CoffeeGrounds
    Every year the world produces a staggering 10 billion kilograms (22 billion pounds) of #coffee waste globally. Most ends up in landfills. We could be producing #concrete that's 30 percent stronger by processing and adding charred coffee grounds to the mix, researchers in Australia discovered.

  4. Even cement likes coffee

    Organic products like coffee grounds can't be added directly to concrete because they leak chemicals that weaken the building material's strength. So using low energy levels the team heated coffee waste to over 350 °C (around 660 °F) while depriving it of oxygen.

    "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! 😃

  7. Oh my....one of the friends, to whom I give lettuces and tomatoes, just dropped this off for me. And, I was just thinking that tomorrow morning I need to feed some of the garden plants. #gardening #CoffeeGrounds #PlantFood
