By Green Living TipsHere's 10 quick tips for reusing coffee grounds:
- If you have a worm farm, dump the grounds in - I swear the caffeine jolt makes the worms chomp through more. But seriously, it doesn't seem to do them any harm; but I'd recommend mixing them through the pile so the worms don't overdose on any residual caffeine.
- Use coffee grounds as a plant fertilizer. Sprinkle the grounds around the base of the plant then dig them in a little. They can also be sprinkled directly on your lawn.
- Add the grounds to compost piles to enrich nutrient content - the grounds contain Nitrogen, Phosphorus, Potassium, Calcium, Magnesium and Sulfur. Phosphorous is becoming scarce, so we need to conserve it as much as possible.
- Add water to the grounds and allow to stand for a day or two. Drain off and then use as a liquid plant fertilizer - cold coffee that you'd usually toss down the sink can also be used in this way.
- After drying the grounds thoroughly, add them to an old stocking. Tie off the ends and then use in cupboards and your refrigerator as an odor absorber. Alternatively, you can just place the dried grounds in a container of some sort.
- Rubbing your hands with used coffee grounds will remove strong smells such as onion or fish.
- Grounds can be used as a scourer for greasy pots and pans
- A ring of coffee grounds around sensitive plants can discourage ants and some other pests.
- Use as a wood stain. Allow them to soak in a small amount of water overnight (or hot water for a shorter period), then drain off. The amount of water you use will determine how dark the stain is. Also good for touch-ups to mahogany furniture.
- This one's interesting and I can't say I've tried it. Dry out the coffee grounds in a warm (not hot) oven; then add equal weight of fresh coffee grounds and then use that mix to create another brew. After that brew, try one of the tips above - I wouldn't recommend repeating the cycle :).
With all these wonderful re-use options for coffee grounds; perhaps hit your local coffee house and ask them if you can collect theirs on a regular basis. They'll reduce waste and you'll have a useful product - everyone wins! You might want to get in quick; since the time this article was originally published it seems many people have been doing just that, so used coffee grounds are becoming quite sought after.
