Coffee, The Multi-Faceted House Tool


At Karajoz, we're all about doing what's best for the earth. Our two biodegradable and composting initiatives let us do what we can to minimise our waste while we work on inventing recyclable coffee packaging.

Not to mention, our coffee itself can be an extremely handy tool to keep around the house, benefiting both your life and the earth around you.

If you make a daily pot of coffee, you have a fabulous source of organic matter right at your fingertips. In compost jargon, coffee grounds are a "green," meaning an item that is rich in nitrogen. This is a great way to use something that would otherwise end up in a landfill.

"Greens" are materials that are rich in nitrogen or protein, and they tend to heat a compost pile up because they help the microorganisms in the pile grow and multiply quickly. 


Coffee & Your Garden

Coffee grounds are an extremely useful tool to keep in your garden shed. Use them for;

  • Put them in your compost bin. Composting coffee grounds is as easy as throwing the used coffee grounds onto your compost pile. Used coffee filters can be composted as well.
  • Sprinkle the grounds on top of your garden of acid-loving plants, or rub into the top few centimetres of the soil. 
  • Create a slug and snail barrier! Coffee grounds are both abrasive and acidic, so a coffee barrier may protect your plants from insects and pests.
  • Make coffee ground "tea." Add two cups of used coffee grounds to a five-gallon bucket of water. Let the "tea" steep for a few hours or overnight. You can use this concoction as a liquid fertilizer for garden and container plants. It also makes a great foliar feed.
  • Add coffee grounds to your worm bin. Add some to your worm bin every week or so, but not too much at once, because the acidity could bother your worms. A cup or so of grounds per week for a small worm bin is perfect.


Other Handy Uses

Keep the leftovers after your morning cup of coffee and reuse this versatile and earth-friendly tool around the house.

  • Deodorise your fridge. Place a bowl of dry grounds in your refrigerator or freezer to neutralize odors left by stale or spoiled food.
  • Clean tools and dishes. Place a few teaspoons of grounds on a thin cleaning rag and use to scour away grease and grime. Finish with a thorough rinsing.
  • Hide furniture scratches. Dip a cotton swab into steeped grounds and dab on scratches in dark wood furniture to minimize them. Just test in an inconspicuous area first.
  • Give paper an antique look. Dip paper or sheets of stationery in a soupy mix of grounds and water; allow them to sit a minute or two, then let dry and brush off the grounds.
  • Repel insects. Mound grounds into a ring to create a protective border around plants that will ward off ants and slugs.
  • Grow blue hydrangeas. Work grounds into the soil at the base of mophead hydrangeas to increase the acidity level. This helps the shrubs absorb aluminum, which you can add to the soil to keep the flowers a vibrant blue.
  • Contain ashes. Sprinkle damp grounds on fireplace ashes to cut down on airborne dust as you sweep them up.
  • Make an exfoliating body scrub. Rub a scoop of grounds between palms as an exfoliant to remove dead skin.
  • Make a cockroach trap. Fill a can or jar with an inch or two of moistened coffee grounds, then line the container's neck with extra-sticky double-sided tape. The scent will draw the roaches into the trap.
  • Fortify house plants. Give seedlings a nitrogen boost by stirring grounds into soil or a watering can.
