Here are 5 ideas of how you can reuse coffee grounds and help reduce your impact on our planet.

Fertilize Your Garden with Coffee Grounds

This is probably the most well-known use for used grounds. Even after brewing, the grounds are filled with essential nutrients required for plant growth. Soil doesn’t naturally have all the nutrients needed for optimal plant growth and can be depleted over time. Used grounds contain minerals that support plant growth like nitrogen, calcium, iron, phosphorus, potassium, magnesium, and chromium. Coffee grounds can help absorb heavy metals that contaminate the soil. They can also attract worms to promote healthier soil. Simply sprinkle used grounds on your soil to unlock these benefits.

Neutralize Orders

Coffee grounds are packed with nitrogen which can help absorb and eliminate odors. Place them in a bowl in your refrigerator or freezer to neutralize any food odors. Small pucks of frozen grounds can be used in a sink’s garbage disposal to neutralize any odors. Dried grounds are also great for removing odors like garlic or onion from your hands. Simply rub the grounds over your hands like you’re washing them, rinse, and wash with soap. Be amazed as the odors are gone.

Cleaning Pots & Pans

Coffee grounds are incredibly coarse and abrasive no matter how fine of a grind. By sprinkling the grounds directly on pots and pans even the toughest mess can be removed with a normal wash. As a bonus, it should also remove any smells that may be on the cookware. Be sure to rinse thoroughly or your next meal could taste like coffee.

Exfoliating Skin & Hair with Coffee Grounds

Coffee grounds are an ideal exfoliating agent that can be easily made into something for skin or hair care. Mixing the grounds with water or coconut oil can make an easy scrub for removing dirt, dead skin, and can even help with acne. You could also massage a handful of grounds into your scalp for a few minutes before shampooing. The antioxidants and caffeine in the grounds can increase blood flow, accelerate hair growth, and promote the overall health of your hair and skin.
