Coffee Grounds: 7 ways to use them

We’re always on the lookout for ways to waste less at home. An easy place to start is with your morning cup of coffee. Did you know that, according to the NRDC, coffee grounds are one of the most commonly thrown-out food items in American households? It’s not that surprising given how much coffee we drink as a country.

While drinking coffee isn’t an issue, used coffee grounds, just like any other food or organic waste, break down in the landfill and produce methane, a harmful greenhouse gas. The good news is that coffee grounds have a lot more value to give us even after the last drops of coffee are gone.

Want to decrease your coffee waste and benefit the environment? Here are some of our favorite tips on how to reuse coffee grounds:

Make Mocha Brownies

Your coffee grounds have more to offer than you might think. In this recipe, melting your butter with spent coffee grounds will imbue the butter with a delicious and aromatic coffee flavor. The addition of your grounds also magically brings out more of the chocolatey flavors hidden in your cocoa powder.

Use coffee grounds to remove odors from fridge

Keep your fridge smelling fresh

Store dried coffee grounds in an open jar anywhere you want to absorb odors. Our friend Joel Gamoran recommends trying this trick for getting rid of fridge odors!

adding coffee grounds to plants

Fertilize acid-loving plants

Add a spoonful of spent coffee grounds every 4-6 weeks to fertilize your indoor house plants.

NOTE: Coffee is acidic, rich in nitrogen, and your grounds may still contain a fair amount of caffeine. All of this can irritate/harm certain plants. Add them in moderation and, when in doubt, double-check online if the plants in question benefit from acidic soil.

compost coffee grounds and food scraps

And if you’ve still got grounds

If you are able to compost through your city compost collection, at your community garden drop-off, or at home, be sure to add your grounds to the mix. They’re rich in nitrogen and can help create fertile soil when they break down. Worms especially love spent coffee grounds.
