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.

    You grind coffee beans and what you have after that is grounds. Not grinds. Just a detail.

    These are great ideas. Just the smell of coffee brewing or smelling the coffee grounds is calming for me. I especially like to use a percolator, the kind with a glass top. watching it bubble up and hearing it perk remind me of Daddy making coffee. mmm mmmm

    A recent journal article in Food and Agricultural Chemistry uses used coffee grounds to make biodiesel.

    Coffee comes from a bean which is an organic material. Hello!!! How does recycling a product that easily biodegrades help the environment. Come on people, let's spend our time on something a little more worth while.

    Did you know that you can (depending of the flavor of the coffee ) bake (lowest temp/warm) the used coffee grounds for kitchen odor control. You would do this during or after cooking fish or meats that other house guests or family members detest. Best results in ovens with con-vection fans. Good Luck.

    Grounds can be emptied into sewer drains but NOT into sepic systems. They take too long to break down and will eventually counter-balance the chemicals you typically have to add to sepics. (plumber's word) Grounds do help repel some insects in gardens and flower beds. Especially effective against slugs and grubs. A TBLS to 1/2 cup added or substituted in any baked chocolate dish gives a delightful extra depth of flavor...even for NON-coffee drinkers. Yes, Karen, dry them before using in stocking as deoderizer; noname...what is monkey butt?

    OH BOY! You guys are really reaching here. I understand recycling, but this is silly. "Dye clothes or paper"? Yeah, that's what everyone wants is coffee stained clothing. Yikes. Nice try, but no sale.

    I don't recommend rubbing coffee grounds on your dog unless the grounds are decaf. Caffeine seeps through the skin, you don't want your poor dog's heart racing.

    I add coffee grounds/the paper filter & tea bags as well to my compost. I have also sprinkled at the base of the house foundation to keep ants away. Dry the grounds before using in nylons, spread on newspaper in the sun until completely dry. Tea is also good as a dye if the item being used is white. Soak item for ten minutes & check for the color your are looking for. Good Luck

    I guess I'll start saving my grounds then! I used to save them but stopped when I started to cut my coffee back. I'm an avid gardener. Used tea leaves also work well in garden soil, if you're a tea drinker.
