7 uses of used coffee grounds:

1. Fertilize Your Garden - Coffee grounds contain several key minerals for plant growth — nitrogen, calcium, potassium, iron, phosphorus, magnesium and chromium. Sprinkle them on top of your plant soil!
2. Add them to your compost heap - It'll take about 3 months for your grounds to become incredibly fertile compost.
3. Remove Fleas from Your Pet - Simply rub the coffee grounds through your pet's hair after shampooing, then rinse them off and let the fur dry as normal. 
4. Neutralise the smell in your fridge - Coffee grounds contain Nitrogen which absorb odours. Place a small bowl in your fridge to absorb any unwanted smells.
5. Exfoliate Your Skin - Combine with coconut oil and scrub into your body and the coarse particles will exfoliate your skin.
