5 Ways to Recycle Used Coffee Grounds

Many of us love a good cup of coffee, but what to do with the used coffee grounds? Here are some suggestions:

  1. Use as a mulch around acid-loving plants: Acid-loving plants include azaleas, camellias, rhododendrons, blue hydrangeas and blueberries.  I have been collecting coffee grinds from our work coffee machine to use around my blueberries, as Adelaide soil tends to be alkaline.
  2. Compost them or use in a worm farm: fairly obvious but true
  3. Bug repellant:  Scatter coffee grounds around near ant nests or around plants easily damaged by snails and slugs to deter the creepy-crawlies.
  4. Natural Dye:  As most of us know, coffee stains when spilt, so use coffee grounds steeped in boiling water as a brown dye for Easter eggs and even clothing.  (First soak the fabric in coffee, air dry it, then wash in cold water to set the dye.)
  5. Fridge deodoriser:  Coffee grounds in a clean, old sock tied at the top can be used to deodorise the fridge, but make sure the grounds are dry or they'll go mouldy.
