Eggshells: The Surprisingly Useful Kitchen Waste

Eggshells, often discarded without a second thought, are surprisingly useful. This humble kitchen waste has a myriad of uses that can benefit your home and garden. Instead of tossing them in the trash, here are some clever ways to make the most of eggshells.

Natural Fertilizer for Your Garden

Eggshells are rich in calcium, which is essential for plant health. Crushed eggshells can be sprinkled around the base of your plants to provide a slow-release fertilizer. This can help prevent blossom-end rot in tomatoes and peppers and strengthen the overall health of your garden.

How to Use:

  • Rinse and dry the eggshells.
  • Crush them into small pieces.
  • Sprinkle around your garden plants.

Pest Repellent

Eggshells can act as a natural pest deterrent. The sharp edges of crushed shells deter soft-bodied pests like slugs and snails, which can wreak havoc on your garden.

How to Use:

  • Crush the eggshells into coarse pieces.
  • Scatter them around plants that are prone to pest attacks.

Compost Booster

Adding eggshells to your compost pile is an excellent way to boost its nutrient content. The calcium in eggshells helps balance the acidity of the compost, creating a richer, more beneficial end product for your garden.

How to Use:

  • Crush or grind the eggshells for faster decomposition.
  • Mix them into your compost pile regularly.

Household Cleaner

Did you know that eggshells can be used as an abrasive cleaner? They can help scrub away tough stains without scratching surfaces. This makes them perfect for cleaning pots, pans, and sinks.

How to Use:

  • Crush the eggshells into a fine powder.
  • Mix with a little soapy water.
  • Use the mixture to scrub stubborn stains.

Natural Bird Feed

Birds need calcium too! Crushed eggshells can be added to bird feed to help our feathered friends, especially during nesting season when they need extra nutrients.

How to Use:

  • Bake the eggshells at 250°F (120°C) for about 10 minutes to kill any bacteria.
  • Crush them finely.
  • Mix with birdseed and place in your bird feeder.

Seed Starters

Eggshells make excellent biodegradable seed starters. They are the perfect size for seedlings and can be planted directly into the soil when it’s time to transplant.

How to Use:

  • Fill clean, half eggshells with potting soil.
  • Plant your seeds in the eggshells.
  • Once the seedlings are ready, plant the eggshells directly into your garden soil.

Beauty Treatments

Eggshells can also be used in DIY beauty treatments. The membrane inside the shell is rich in nutrients that can benefit your skin.

How to Use:

  • Rinse and dry the eggshells.
  • Crush them into a fine powder.
  • Mix with egg white and apply as a face mask.


Next time you crack open an egg, think twice before throwing away the shell. From enriching your garden and repelling pests to boosting your compost and feeding birds, eggshells have a variety of practical uses. Embrace this eco-friendly approach and make the most of this versatile kitchen waste. You’ll be surprised at just how beneficial eggshells can be!
