Don’t Toss Your Shells! Creative Uses for Eggshells at Home

Ever tossed an eggshell into the trash and thought, “What a waste”? You’re not alone. Eggshells, often dismissed as kitchen waste, are surprisingly versatile and can be repurposed in numerous eco-friendly ways.

It’s time to open your eyes to the untapped potential of eggshells. Whether you’re an avid gardener, a creative DIY enthusiast, or just someone keen on reducing waste, you’ll find something useful here.

Key Takeaways

  • Eggshells are a rich source of calcium carbonate and can serve numerous eco-friendly purposes including gardening, home use, health supplements, and craft creations.
  • In homes, eggshells can function as eco-friendly kitchen cleaners. They can be used for making DIY jewellery or serve as creative candle vessels.
  • Ground eggshells can provide a source of calcium supplement, while powdered eggshells can be used as a face mask for skincare.
  • The artistic potential of eggshells is vast, from crafting mosaic artwork to creating Christmas ornaments or candle holders.

Eco-Friendliness of Eggshells

Consisting of nearly 95% calcium carbonate, eggshells rapidly decompose, returning beneficial minerals to the soil through as they break down naturally. Eggshell diverts kitchen waste from landfill, reducing emission of potent greenhouse gases like methane. The Environmental Protection Agency (EPA) cites that wasted food makes up 24% of solid waste in landfills and 22% of solid waste incinerated.[1] Though eggshells are a small portion of this, every step counts to cut waste percentages.

Rethinking the way we view eggshells, it’s essential to recognize eggshell recycling as more than a series of DIY projects, instead forming part of a larger initiative to combat the waste crisis. It’s all about changing mindsets.

  • Generating less waste
  • Putting less pressure on landfills
  • Reducing your carbon footprint
  • Contributing to an overall healthier planet

Recycled eggshells have been used in various scientific and industrial applications. There are even efforts to use eggs as sustainable packaging material. Every reused eggshell that eliminates the use of plastic, chemical fertilizers, or other harmful materials is a win in our book.

Ways to Reuse Egg Shells in The Garden

Eggshells come packed with beneficial minerals and nutrients adding value to your gardening regime. Here are three smart ways to recycle eggshells in your garden.

Mixing eggshells in garden soil with sprouting plants

Making a Natural Fertilizer

Here are a few different ways you can use finely ground eggshells as a natural and effective fertilizer!

  • Sprinkle directly on soil – If you’ve already planted and want to give your plants a little boost, you can add some ground eggshells right on top of the soil around the base of your plants. This will break down and fertilize your plants as you water.
  • Mix in with soil – You can take finely ground eggshells and mix them in with your soil directly to create a great garden mix.
  • Fill toilet paper rolls – Take your finished toilet paper rolls and fill them with finely ground eggshells. Work them into your garden soil. Not only will the roll break down into compost, but it will slowly release the benefits of the eggshells into your soil.

The high calcium carbonate content in eggshells boosts soil health, adding nutrients that help plants thrive. It’s an easy way, you’ll find, to enrich your garden.

For those of you with worm composting bins, ground eggshells serve as a fantastic addition, balancing the pH in the bin and ensuring your worms stay happy and productive.

Creating a Pest Deterrent

Egg shells, crush them into small bits. Sprinkle them around your garden plants. In minutes, you’ve created a natural, non-toxic pest deterrent that also fertilizes!.

The sharp edges of the crushed shells deter pests such as slugs and snails, keeping them away from your precious greens. It’s a safe, eco-friendly way to maintain your garden without resorting to potentially harmful pesticides.

Forming a Seed Starter

You can even use eggshells as a biodegradable and self-fertilizing seed starter!

  1. Halve your saved eggshells neatly.
  2. Fill them with potting soil.
  3. Add seeds.
  4. Water regularly
  5. Crack the bottom (for root growth) and plant the full eggshell once the plant is established enough to move outside.

The calcium in the shell provides essential nutrients to young seedlings allowing them to flourish. Once the seedling is ready for transplanting, plant the entire shell in the ground. The shell biodegrades, continually delivering nutrients to the soil.

What Kind of Garden Plants Benefit Most from Eggshells?

Eggshells are excellent sources of calcium, which is crucial for plant growth, particularly for preventing blossom end rot in fruiting plants. Plants that benefit most from eggshell fertilizer include:

  • Tomatoes
  • Peppers
  • Eggplant

These plants are typically more prone to a deficiency in the great nutrients that eggshells provide. Leafy greens like spinach and Swiss chard also thrive with an added boost of calcium. By crushing eggshells and sprinkling them into the soil, gardeners can enhance plant health and promote stronger growth, ensuring these plants receive the necessary nutrients for optimal development.

Innovative Uses of Egg Shells Around The House

Crushed eggshells in a jar in the kitchen with pots

Going beyond the garden, eggshells find numerous applications within your home. Let’s discuss a few that not only serve functional purposes but also keep the environmental footprint minimal.

Eco-Friendly Kitchen Cleaner

Consider eggshells as nature’s gift for a cleaner kitchen. Instead of harsh chemicals or abrasive cleaning aids, reach out for crushed eggshells. Ground into a gritty texture, they provide a non-toxic way to scrub away stubborn stains or food residues on your pots and pans. Store a jar of powdered eggshells near your sink, making it easy to grab when cleanup duty calls. To use, mix the shell powder with a little water to form a paste. Apply this mixture to the stained surface and scrub away gently. However, avoid using on non-stick or other sensitive surfaces, as the shell particles may cause minor scratches.

DIY Jewelry from Egg Shells

Dazzle your friends with unique fashion accessories made from eggshells! When finely crushed, the pieces can mimic the look of delicate sea coral or add an organic aesthetic to your DIY projects.

  1. All you need to do is gather some eggshells, a jewelry kit, paint, and clear-drying industrial glue.
  2. Clean and sterilize the eggshells before smashing them into small pieces.
  3. Color them as per your liking with paint and let it dry.
  4. Arrange the colored shells onto your jewelry piece.
  5. Once satisfied with your design, adhere the eggshells using the industrial glue.

Egg Shell Candles

Ever thought eggshells could illuminate your nights? Creating candles with eggshells isn’t just a fun DIY project, but it brings a rustic charm to your home décor. You’ll need clean eggshell halves, wax flakes, cotton wicks, and a heat source. Start by melting the wax flakes using a heat source like a candle. Carefully pour the melted wax into the shells and quickly place a wick in each. Allow the wax to harden, and voila, homemade eggshell candles that sparkle with sustainability and creativity. Add a few drops of your favorite essential oils into the wax for a scented variant.

Just be careful as they burn. It’s best to set these up in small shot glasses or another container to keep them in place and easy to monitor while lit.

Surprising Health and Wellbeing Uses

The wonders of eggshells transcend garden and home. There’s more – the intriguing health and skincare potentials that offer a holistic approach to sustainability and wellbeing.

Egg Shell Calcium Supplements

Eggshells, predominantly calcium carbonate, present an untapped source for nutritional supplementation. Ground eggshells, when consumed in measured quantities, suffice as calcium supplements.

First, clean the eggshells thoroughly. Rinse under running water to wash off any egg residue. Post that, you’d bake them at 200°F for about 10 to 15 minutes. Once cooled, grind them into a fine powder, which can be easily integrated into your daily diet. Stir into foods, sprinkle atop dishes, or encapsulate in small, swallowable form.

Please note that this is not medical or health advice. It’s important to do your own research and monitor your body whenever introducing new foods, supplements, or habits. This method has been practiced and proven effective in studies.

Egg Shell Face Mask for Skincare

Eggshells aren’t just nutritionally valuable; they’re also a boon for skincare. Powdered eggshells serve as a gentle, natural exfoliant. They help eliminate dead skin cells without the harshness of chemical peels or scrubs.

To create this rejuvenating face mask, wash, dry, and finely crush the eggshells akin to the method described above. Combine the powder with other skin-friendly ingredients such as honey or yogurt, creating a paste. You can experiment with different ingredients and perfect your recipe. Here’s an example:

  • 1 tablespoon of eggshell powder
  • 1 tablespoons of organic raw honey

This eco-friendly skincare solution, though unconventional, contributes to reducing personal carbon footprint while catering to your skin’s health. Respecting the environment doesn’t end with gardening or chef duties; it extends to include even the most personal self-care routines.

Remember, as with any new supplementation or skincare regimen, it’s prudent to consult your healthcare provider or a skincare specialist. They can guide you based on individual needs and assure a safe, beneficial experience.

Creative Craft Ideas With Egg Shells

Eggshell arts and crafts with painted eggshells, mosaics, and candles.

Continuing with the theme of functional eggshell applications, let’s take a closer look at the artistic potential the humble eggshell holds. As a crafting material, eggshells can add a unique touch to many creative projects, from mosaic art to holiday decoration and even candle holders.

Egg Shell Mosaic Art

You can transform discarded eggshells into a marvel of artistic expression, creating mesmerizing mosaic art pieces. Start by cleaning and drying the eggshells, and apply natural dyes if desired, giving them vibrant hues. Crush the shells into smaller pieces, yet not too fine – you’re aiming for a mosaic, not a powder. Then, use a pencil to sketch a pattern onto a surface of choice – a wooden piece, a glass frame, or even a ceramic pot. Apply craft glue to small sections of your pattern, and carefully press your colored eggshell pieces onto it. Continue until your artwork is complete, and let it dry properly.

Egg Shell Christmas Ornaments

Instead of purchasing store-bought ornaments, consider crafting bespoke ones using your waste eggshells. By simply applying a little acrylic paint or glitter to cleaned and dried eggshell halves, you can bring to life beautiful, eco-friendly ornaments. Light, delicate, and aesthetic, these handmade eggshell ornaments add a touch of originality to your festive decor. And not to mention, crafting these ornaments can turn into a bonding family activity around the holidays.

Egg Shell Candle Holders

Here we have another exciting way to repurpose eggshells. Turning them into unique candle holders not only yields a useful item but also provides a platform to flaunt your creativity. Ensure that the eggshells are clean, dry, and cracked at a height to accommodate a tealight candle. Adorn the outer shell with paints, glitters, or lace, or opt for simplicity by keeping it natural. Place your tealight inside and enjoy the warm, gentle glow of your handmade eggshell candle holder.

So, embrace your creative flair and give these ideas a try. You’ll be pleasantly surprised by the myriad of items you can make from something as simple as eggshells, all while promoting sustainability. And don’t overlook the joy of crafting, as it’s a great way to relax and unwind while creating beautiful pieces for your home or to gift.
