Recycling your used coffee grinds

Did you know that the average American consumes about 3 cups of coffee a day? That’s a lot of used coffee grinds going into the trash.

There are actually many ways you can recycle and reuse your old coffee grinds to help preserve the environment and maintain your health.  And for other ways to green your caffeine, check out the wiki all about having an eco-cup o' joe or maybe even look into drinking organic coffee!

A Cup of Joe Goes a Long Way

You’d be surprised at just how many different methods have worked for people:

  • Touch up furniture and other wood scratches with grounds and a Q-tip.
  • Sprinkle around areas where pesky insects, slugs and snails dwell to drive them away.
  • Mix with soil as a natural fertilizer for plants.
  • Dye clothing or paper.
  • Rub into your dog as an organic flea dip.
  • Fill old nylons and hang in your closet or fridge to repel odors.
  • Use to fill old pin cushions.
  • Scrub away grease and grime from pots and pans.
  • Throw on ashes before cleaning out the fireplace to reduce dust from spreading.
  • Feed to worms to help with your garden.
  • Rub on your hands to eliminate odors.
  • Mix ¼ grinds with one egg white and massage onto face like a mud pack.

If you’re not an avid coffee drinker but you live near a coffee shop or cafe, you can always ask them for the old grinds. Places like Starbucks actually give bags of used grinds away to people who use them for their home and gardens.

Recycling is just one way that we can help maintain the natural beauty of our environment, so next time you drink a cup of coffee save those coffee grinds for future use.

    Composting coffee grounds with banana peels and eggshells gives a balanced NPK (nitrogen, phosphorus, potassium - also has some calcium from the shells) fertilizer. I fill the middle third of plant pots with this and then plant my seedlings or planter items. A handful of peatmoss (already sopping wet) goes on top, then the last third as the first third, of potting soil.

    Plant marigolds, the smellier the variety the better, around the tomato plants. Don't use hybrid marigolds, just the old-fashioned small-sized plant variety. Seeds cost nothing if you can get an expired flowerhead--seeds are obvious when you break apart the head. Still, every once in a while look for hornworms. Small jar lids with beer will take care of slugs.

    Dry coffee grounds are a great sensory tool for kids or adults who have sensory issues. Dry them and put them in a bucket or pan and have them run their hands thru them. Good, cheap, non-toxic and relatively low allergy. Schools can use all the help they can get!

    Just wondering, has anyone used it for the flea dip? If so did it work out.

    Been using the grounds for tomatoes and feeding the worm pit. The grounds acidify the soil making tomatoes sweeter. Thanks for the additional tips!

    Ground Termites hate it too. I lost a few palm trees to these blighters before I started tossing the grounds into my garden. So, I wonder if it is a good solution to termite-proofing wood rather than using arsenic and copper sulphate as is a common commercial practice here in Oz?
