Going Green: 21 Ways to Reuse Coffee Grounds

It’s the first Friday of the month, which means it’s time again to talk about Going Green. Last month we discussed green cell phones and cell phone recycling, and today we’re moving on to another way to recycle and reuse.

And we’re talking coffee. Coffee grounds, actually.

As you well know, I drink coffee, and apparently so do many of you; coffee is the most consumed beverage worldwide with 400 million cups downed each year. Now that creates a lot of used coffee grounds!

Did you know there are lots of ways you can reuse coffee grounds instead of just throwing them in the garbage? Here’s a short list:

21 Ways to Reuse Coffee Grounds (and Coffee)

In the garden:

1. Organic fertilizer: Sprinkle them in the soil of plants that love acidic soils, especially rosebushes (my roses *love* coffee grounds!), rhododendrons, camellias, evergreens, carrots, and radishes.

2. Organic pest and ant repellent: Sprinkle areas where ants, slugs, and snails hang out and destroy your garden.

3. Organic cat repellent: Yes, I love cats, but if you want to keep them out of your plants and garden, coffee grounds will do the trick.

4. Mushroom growing soil: Inoculated mushroom plugs nestled into moist coffee grounds can mean a great mushroom crop for you. Put grounds in a glass container and press a mushroom plug into them, repeating with more grounds and mushroom plugs until you run out of room. If you see mold, just remove it.

5. Bait worm life support: Add coffee grounds to soil to help keep bait worms alive longer.

In the house:

6. Closet deodorizer: Old pantyhose plus coffee grounds equals a sachet to keep your closet free of odors.

7. Refrigerator and freezer deodorizer: Place ground in a small cup and in the fridge or freezer much as you would baking soda.

8. Pin cushion filler: If you still use pin cushions (like I do), dried coffee grounds are a great filler for the cushions.

9. Abrasive cleaner: For stubborn grease and stains on pots and pans, coffee grounds really get in there and do the job.

10. Dust deflector: We’re talking about the fireplace here; sprinkle coffee grounds on ashes before you start collecting them to minimize the dust. I *love* this tip and use it often.

11. Furniture scratch toucher upper: Use a Q-tip and coffee grounds to fill in scratches on wooden furniture–remember the coffee will stain the wood a bit, so don’t use it on something that won’t match.

12. Drain cleaner: Be careful with this one as you don’t want to clog your drain with coffee grounds! *But* to counter odors coming from your drain, you can pour about a half a cup of coffee grains down the drain followed by boiling hot water to get the grounds through. No more smells!

13. Meat tenderizer: This is one for leftover coffee as opposed to coffee grounds; soak steaks in coffee to tenderize and for an interesting added flavor.

14. Chocolate cake flavorer: Used grounds and fresh grounds both give a little kick to chocolate baked goods, including brownies.

In your beauty routine:

15. Hand soap: Rub grounds on your hands to get rid of stubborn odors like onion and garlic. In fact, the soap I use in my kitchen is made with used coffee grounds–Caffè Vaniglia soap from Saponissimo.

16. Face mask: An egg white mixed with 1/4 cup grounds makes a great exfoliating face mask.

17. Hair rinse: After washing your hair, rub in coffee grounds for shine, softness, and even a bit of color for those of you who are dark-haired; remember coffee grounds act as a dye, so if you have light hair, unless you want highlights, this one isn’t for you.

18. Cellulite rub: Mix one tablespoon of olive oil with 1/4 cup moist, warm coffee grounds and spread on cellulite hot spots. Wrap tightly with plastic wrap, leave on for a few minutes, and then remove wrap and shower as normal. For best results, do a couple times a week. If anyone tries this, you *must* let me know how it turns out.

For fun:

19. Dye: Use a mix of coffee grounds and water to dye clothing, paper, or even Easter eggs.

20. Tattoo base: Make homemade temporary tattoos using coffee grounds and henna.

And finally, on your doggie:

21. Dog flea dip: I haven’t had the nerve to try this one yet, but next bath time, my dogs are getting some coffee grounds rubbed into them after the shampoo and rinse routine.

By the by, even if you don’t drink coffee, you can ask your local coffee shops and other places that serve coffee for their grounds, and start reusing them. The environment will thank you!

Do you currently reuse coffee grounds? How?

If you don’t reuse coffee grounds, which of these suggestions might you try?

Buon weekend & Happy Birthday Dad!

be careful with the puppies though – when using coffee grounds in the garden, it’s best to use it on plants that the dogs are not attracted to or have your garden fenced off where they cant get into it (unless you’re one of the lucky ones and your dogs dont dig up your garden). Dogs can make themselves very sick on coffee grounds.

coffeejitters (Judy Haley)’s last blog post..The Best Thing

I was under the impression that the presence of coffee grounds there would make animals turn the other way so they don’t eat the plants or go to the bathroom on them. Sorry, do other dogs eat dirt? Mine don’t so I didn’t know that mixing in coffee grounds would somehow make it appealing?
awedree on 06 Mar 2009 at 8:11 am #

Buon venerdi, Michelle. Thanks for those cool suggestions. With the weekend coming (TG!) I’m in the mood for some pampering, so I’d like to try the face mask and maybe even in my hair.

I haven’t done the face mask yet, but it sounds lovely. The hair rinse can be a bit messy so be sure to position yourself well
Sonia P on 06 Mar 2009 at 8:34 am #

Buon giorno Michelle! Thanks for all of the great ideas! I will definitely be trying some of these.

Hi! Thanks for the wake up call on coffee grounds. For years we saved them for the garden and all of a sudden we stopped. We have a flower bed that has lousy soil and you woke me up on how to improve it.

Think Spring!

Excellent point…spring is coming!

Really great tips, Michelle! We have a little mountain of coffee grounds in the kitchen that we usually throw out but I’m definitely going to reuse them now, especially for cleaning the fireplace and in the garden. We have a lot of neighbourhood cats visiting our place so hopefully the grounds will keep those pests away. I’m tempted to use grounds for cat flea dip but I’m afraid of what would happen.

saretta on 06 Mar 2009 at 11:28 am #

Who knew? I just throw mine in the compost.

That works too
karen on 06 Mar 2009 at 12:11 pm #

I had the most amazing coffee ground soap that I just finished. I used it in the shower and although the grounds made it rough, it was the best exfoliating soap I’ve ever used. Dry, flaking, bumpy skin from a harsh winter, gone! I may have to try some of your soap and try and keep the cats from using my herb garden as their litter box! great tips.

karen’s last blog post..The Mainland

I can’t tell you how many times I’ve seen kitties squatted in plants around the village…I may just have to start sprinkling random plants as a neighborly deed And YES the grittiness of the coffee grounds is a great exfoliator…another reason why I do want to try that face mask….
erin :: the olive notes on 06 Mar 2009 at 1:53 pm #

good tips Michelle! Chris and I have been talking about this recently too…he’s been using them in our garden…but I love #3, b/c we always need something to keep our cats out of our houseplants I’ll definitely try it.

RE: # 13 – a girlfriend of my swears by this little trick: When pan frying a steak (seasoned steak fried in butter), she pours a little black coffee over the meat and in the pan when it’s close to done. Her steaks are delish!

#18 – This should really help!! I used to work for a skin care company based out of France (Lierac). Their cellulite reducing lotion was almost always sold out. The lotion contained a good amount of caffiene.

These are all great ideas… maybe I need to start drinking coffee so I can reuse the grounds.

Hah, well, that’s certainly an option…or you can just go to a local coffeeshop and ask them for their grounds

For a wake me up scrub in the shower, mix 1/4 cup olive oil, fine sugar and used coffee grounds. Apply in a circular motion to scrub off dry skin and reveal soft, smooth skin all over. Breathe in the scent of coffee as you shower — great in combo with a mint body wash, you’ll feel refreshed and awake!

I use them in my sink. I put them in the garbage disposable and goodbye odors. I will definitely try them in my roses this year. Thanks for the tips.

Definitely works on odors!

Oh, and I almost forgot. Last week I had a steak in a restaurant that was marinated in espresso. Yum.

I’d love to try that, especially in a restaurant where I can’t screw up my steak!
Laura on 07 Mar 2009 at 9:34 am #

Ciao Michelle! Thanks for the great tips! I am especially excited about the garden uses for coffee grounds. I think I was a bit overzealous in my pruning of two lovely hydrangea bushes in my garden earlier this month (the adventures of the amateur gardener continue!), and I think some coffee grounds might just give them a little push. I remember reading somewhere that they like acidic soil. The rosebushes will be happy, too! I also had a problem last summer with ants in the garden, and I had no idea those coffee grounds I was throwing away each day would do the trick. Oh, and don’t get me started on cats in the garden! Thanks for all the great tips!

Laura’s last blog post..The Tour of the Winds

I hope the tips help your garden! I don’t know about your house, but we go through quite a bit of coffee grounds, so it’s nice to have different options for using them
anna l'americana on 07 Mar 2009 at 1:39 pm #

Always tossed grounds on the compost pile, didn’t realize they were good for snails and slugs. How much happier my last garden (and I) would have been! I used to go out and pick the suckers off by hand they made me so mad. And I’m about the most squeamish person you’ve ever met!

I’m definitely going to try the fireplace ash removal method.

And I’ve never heard of using them in personal grooming, although their use as an exfoliator doesn’t surprise me. But the hair thing, really? And as a meat tenderizer? I don’t think I could try that last one.

anna l’americana’s last blog post..No smoking in the dark….

I wouldn’t have thought of it either, but others here have praised the use of coffee with steak…who knew?!
Katey B on 07 Mar 2009 at 2:33 pm #

Hi thank you for the tips.

I have a big problem with the neighbours cats digging up my garden so shall be trying 3.

Also, my new holiday flat in Calabria has a wardrobe which smells, so when I’m next in Italy I shall try no 6. Now as I don’t drink coffee how do I ask my neighbour for her coffee grounds in Italian?

I believe coffee grounds is “caffé usato”…mi puoi dare/posso prendere il vostro caffé usato? Be ready for strange looks, I’d say
White On Rice Couple on 08 Mar 2009 at 12:54 am #

Brilliant tips. Neither of us have heard of 3/4ths of them. The roses have always been the luck recipients of our used grinds, but now they might have to share a bit. Especially with the lettuce, the snails’ favorite snack. Thanks for such an informative post. Todd.

Michelle, what excellent tips. I’m a heavy coffee drinker so I always have coffee grounds. Instead of just tossing them out, from now on I will find a use for them I like the ant repellent, the abrasive cleasnser and the cellulite buster! I’ll let you know how it works out.

Pat on 09 Mar 2009 at 6:20 pm #

I heard about coffee grounds being good for acid loving shrubs and started using mine around my rhododendrons a few years ago. The shrubs never looked better and the grounds also seem to keep the leaf biting ants away from the leaves!

I’m tempted to try the cellulite cure..lol!

Pat’s last blog post..Katz’s Delicatessen ~ Where Harry Met Sally

I’m definitely tempted too Pat….thanks for the report on the rhododendrons!
Nate on 09 Mar 2009 at 10:03 pm #

I usually put it in the compost pile or mix it into the soil directly.

I think you have to use a LOT of coffee grounds for it to be effective against snails and slugs.

The meat tenderizer tip is interesting. May have to try it.

Nate’s last blog post..Broiled Salmon Collar Recipe

Thanks for the info on the snails/slugs…yes it does make sense that you’d need to add a lot to the soil otherwise they could probably figure out a way to avoid it pretty well….
Judith in Umbria on 11 Mar 2009 at 10:01 am #

My critters have not found coffee grounds very repellant. I love to use them in the garden and my animals love to lie all over them just like everything else.

Chickens are really turned on by coffee grounds. Try it! I allowed my chickens in WV free access to the compost pile and coffee grounds were the reason for a shrieking fest, with every girld ruffling herself up trying to be first at them.

I tried the coffee ground in my face and it works! tt’s like a mud pack..my skin becomes clear and soft…but is it advisable to use it everyday?

Oh I definitely wouldn’t do it everyday…probably once a week is plenty, like many masks
