by Kiyara Thring

Many of us can't imagine starting our day without a cup of freshly brewed coffee. But did you know that your used coffee grounds can be given a second life, too? Instead of tossing them in the trash, consider these 10 environmentally friendly and practical ways to repurpose used ground coffee. By reusing coffee grounds, you'll not only reduce waste but also contribute to a more sustainable lifestyle.

Natural Fertilizer:

Coffee grounds are rich in nitrogen, phosphorus, and potassium - the essential nutrients for plant growth. Simply sprinkle the used grounds around the base of your plants or mix them into the soil, and watch your garden thrive. As an added bonus, the grounds can help deter pests like slugs and snails.

Compost Boost:

Adding coffee grounds to your compost pile can accelerate the decomposition process and provide vital nutrients to the mix. The grounds are a nitrogen-rich green material that balances well with carbon-rich brown materials like leaves, grass clippings, and paper.


Odour Absorber:

Used coffee grounds can act as a natural deodoriser by absorbing unpleasant smells. Place some in a small container or a porous fabric bag and put it in your refrigerator, car, or gym bag to keep odours at bay.

Eco-Friendly Scrub:

Coffee grounds have a slightly abrasive texture, making them perfect for scrubbing pots, pans, and surfaces without resorting to harsh chemicals. Just mix the grounds with a little bit of water or dish soap to create a paste and scrub away.

Natural Dye:

Used ground coffee can serve as an eco-friendly alternative to chemical dyes. You can dye fabrics, paper, and even Easter eggs with a simple coffee ground solution. Steep the grounds in hot water for a more concentrated dye, or experiment with different soaking times to achieve various shades of brown.

Insect Repellent:

Sprinkle used coffee grounds around your outdoor seating area or garden to deter ants, mosquitoes, and other insects. The strong aroma of coffee confuses their sense of smell and keeps them at bay.

Homemade Candles:

Reuse old candle wax and add used coffee grounds to create unique, eco-friendly coffee-scented candles. The grounds will release a pleasant coffee aroma when the candle is lit, and you'll be reducing waste in the process.

Exfoliating Body Scrub:

Combine used coffee grounds with coconut oil and sugar for an invigorating and eco-friendly body scrub. The grounds will help exfoliate dead skin cells, while the coconut oil moisturises and nourishes your skin.


Wood Stain:

Create an eco-friendly wood stain by steeping used coffee grounds in hot water. Strain the liquid and apply it to untreated wood with a brush or cloth. The coffee stain will give the wood a rich, warm colour.

Coffee Playdough:

Mix used coffee grounds into your favourite homemade playdough recipe to create a coffee-scented, textured dough. This sensory activity is perfect for kids and adults alike!

By repurposing used ground coffee, you can play a part in reducing waste, conserving resources, and embracing a more sustainable lifestyle. With these 10 ingenious ideas, you're well on the way to transforming your coffee waste into an eco-friendly treasure. Give them a try and discover the potential of used ground coffee to make a positive impact on our planet.
