10 Eco-Friendly Household Uses for Eggshells

Updated: Sep 7, 2023

Eggs are a staple in many kitchens, but did you know that eggshells can be repurposed in numerous creative ways? In this article, we will explore ten practical and cost-effective ways to utilize eggshells around your home. From gardening to cleaning, we’ve got you covered with these innovative uses for eggshells that are both beneficial for the environment and your daily life.

  1. Nutrient-Rich Fertilizer: Eggshells are an excellent source of calcium and other minerals, making them a natural fertilizer for your plants. Crush the eggshells into a fine powder and sprinkle them in your garden or mix it with soil to enhance the nutrient content. This organic boost will promote healthier growth and prevent calcium deficiencies in your plants.

  2. Pest Deterrent: Crushed eggshells can act as a natural deterrent for pests such as slugs, snails, and other crawling insects. Scatter the crushed eggshells around vulnerable plants or create a protective barrier to keep unwanted critters at bay. The sharp edges of the shells deter pests, safeguarding your garden from harmful chemicals.

  3. Seedling Starters: Eggshells make fantastic biodegradable pots for starting seedlings. Gently crack the top part of an egg, remove the contents, wash the shell, and fill it with potting soil. Plant your seeds directly into the eggshell pot, providing a nourishing environment for the young plants. Once the seedlings are ready to be transplanted, you can directly plant the entire eggshell into the ground.

  4. Coffee and Tea Stain Remover: Eggshells possess gentle abrasive properties that make them ideal for removing stubborn stains from cups, mugs, and thermoses. Crushed eggshells combined with a little water form a natural scrub that can effectively tackle coffee or tea stains, leaving your favorite drinkware sparkling clean.

  5. DIY Calcium Supplement: Instead of discarding eggshells, you can transform them into a calcium-rich supplement for your body. Thoroughly clean and bake the eggshells to sterilize them, then grind them into a fine powder. Add a teaspoon of this powder to your favorite smoothies, juices, or recipes to increase your calcium intake naturally.

  6. Drain Cleaner: Eggshells, when crushed into small pieces, can help keep your drains clean and odor-free. Drop a few crushed eggshells down your kitchen sink or garbage disposal, and as they break down, they will help scrape away buildup and absorb unpleasant smells, maintaining a healthy flow in your pipes.

  7. Candleholders: Get creative with eggshells by repurposing them as unique candleholders. Clean and dry the shells, then carefully position small tea light candles inside each one. These charming and eco-friendly candleholders will create a cozy ambiance for any occasion.

  8. Composting Aid: Eggshells are a valuable addition to compost piles. They add essential minerals to the mix while also balancing the pH levels. Crushed eggshells can be added to your compost bin or directly into your garden soil, enhancing the compost’s quality and promoting a healthier environment for your plants.

  9. Artistic Mosaic Crafts: Unleash your artistic side by using crushed eggshells to create stunning mosaic designs. Mix the crushed eggshells with a bit of glue or paint and apply the mixture onto various surfaces such as picture frames, flower pots, or jewelry boxes. The result is a beautiful, textured artwork with an eco-friendly twist.

  10. Natural Cleaner for Pots and Pans: The abrasive nature of crushed egg shells makes them a great natural cleaner for pots and pans.
