Don't throw away those coffee grounds quite yet. Although it may be second nature to toss your used coffee grounds each morning after that cup of joe, these tiny granules can be repurposed and used in a myriad of ways. Here are a few of the best ways that you can lean into the sustainability movement by reusing the coffee grounds in practical ways around the house.

Uses for Grounds Outside

Leverage the nitrogen in coffee to use in an at-home compost bin. Science has shown that compost based on grounds is richer in nutrients than compost made with only food scraps. This is because the coffee grounds work as a "green" material to ferry essential nitrogen to support microbial activity. You can take this one step further by using the coffee grounds in your home garden to amplify the natural nutrients in the soil.

You may love the smell of a freshly brewed cup of coffee, but did you know that insects and pests actually abhor this scent? You can keep snails and slugs away by setting out containers of coffee grounds around your patio area. The presence of coffee grounds will also deter mosquitoes, fruit flies, and ants from invading your outdoor space.

Coffee Grounds in the Kitchen and Around the House

The naturally abrasive qualities in coffee grounds serve many purposes around the home. Try adding a few pinches of these grounds to your favorite dish soap to scrub away scum and food left on pots and pans. While most heavy-duty cookware can withstand this abrasion, be careful using it on more delicate surfaces so that you do not inadvertently scratch them.

The high acidity level of coffee grounds also works wonders as a meat tenderizer. Rubbing these grounds into the protein of choice roughly an hour before cooking will help to promote a more tender finished product. As a bonus, the grounds also deliver an earthy and richer flavor to the meat, adding another layer of flavor to your meal.

Instead of using baking soda as an odor neutralizer, next time try coffee grounds. Place little bowls of these used grounds in the refrigerator, kitchen cabinets, or any area of the house where odor tends to congregate. You do not need a lot of grounds to make a big difference.

Wet coffee grounds can also work miracles on scratched furniture. This technique is best tried on darker woods. Simply apply the wet grounds gently with a Q-tip and let them sit for a minute or two. The dark pigment in the grounds helps camouflage the scratch.

Beauty and Hygiene Purposes

Now it is time to take these grounds into the bathroom and see what kind of magic they can perform in this part of the house. Caffeinated coffee grounds are great at removing excess build-up from the hair. The grounds also have been shown to liven up dull hair and mitigate hair loss. Massage the grounds into the scalp for the best results. Blondes will want to be careful not to leave the grounds in the hair for too long, as it can lead to discoloration.

While you are using the grounds in your hair, be sure to set some aside to make a body scrub. Combine about a half cup of used coffee grounds with a quarter of a cup of moisturizing kitchen oil. Good choices include olive oil or coconut oil. Add in a splash of your favorite essential oil for a bit of scent. Mix all of this together, and you have a body scrub made with natural and sustainable ingredients. You may never go back to paying money for commercial scrubs again.

Lastly, try using the coffee grounds to make an under-eye treatment made with just two ingredients. The caffeine in the grounds serves as a natural pick-me-up when applied to the skin. Combine about two teaspoons of coffee grounds with about half a tablespoon of honey or egg whites. Pat this mixture right under the eyes and let it soak in for about 15 minutes. Wipe away with cold water to reveal fresh and re-energized eyes.

Do your part to protect the environment each morning by hanging on to those coffee beverage byproducts. Not only will you feel good about your sustainability efforts, but you may also save money.
