Can You Recycle Egg Shells?

Recycling things have come to be part of all Americans. In most situations, the first thing that comes to mind when they come across things considered useless is whether they can recycle them. While this is the way to go, particularly considering the environmental effect, we have to pause what we consider recycling.

No. Eggshells are not recyclable. Technically, some people may argue that you can recycle eggshells. But an examination of their stance will reveal that what they are confusing for recycling, is in the real sense, composting. We will still get to the relationship between your eggshells and your compost bin. But let’s explain why you cannot recycle your eggshells.

You cannot recycle your eggshells simply because they are considered food items. Most food items are not storing enough to undergo recycling and still be out for other uses. Besides, there is no identifiable manufacturing potential for an eggshell. So, why waste time and resources recycling them?

These are the reasons that recycling stations often don’t consider eggshells as a recyclable material. So, do yourself a lot of good and don’t drop it in your recycling bin. If you do, you would be creating a problem for the recycling station. Aside from the fact that they would require effort and time to sort, the eggshells could contaminate other recyclable material. As you can see, you are doing a lot of time and energy by not putting your eggshells into the recycling bin. You are also saving other recyclable materials.

But then, you have seen that eggshells cannot be recycled. Does this, however, mean that it is useless? This is not entirely true. Below, we have considered other ways that your eggshells are useful.

Eggs, as well as their shells, come from a natural source. This means that their biodegradability level is high. So, you can always drop your eggshells in the compost bin without any major concern about spoiling your compost.

Aside from this, eggshells are a major constituent of calcium. When you add them to your compost, you are adding calcium to your compost. This calcium helps plants build a strong cell wall that fosters their growth. Depending on your plant, the amount of calcium would go higher. For instance, if you have a tomato garden, calcium in the compost is very important.

In all, understand that eggshells can form a great part of your compost bin. So don’t be afraid to toss the eggshells in the compost bin.

This, however, does not mean that you should treat them with abandonment. You still have to ensure that you properly dispose of them or use them for compost. Alternatively, you can put them to different amazing uses. We will get to this later, but let’s quickly consider if eggshells are good for your plants.

5. For Compost And Gardening

As said earlier, while eggshells are not recyclable, they can be used for compost. They are not only biodegradable, but they are also very rich in calcium and, as such, serve as nutrients for your soil, and by extension, your plants.

7. Glue

While eggshells in themselves do not have gluing properties, they can strengthen that glue that doesn’t seem to be holding. The sand-like quality can help the glue hold better, especially when trying to glue plastic together. After applying glue on the two surfaces, hold together and sprinkle some finely ground eggshells on the broken pieces’ meeting point. Hold together for a while, and there you have it, sealed.

8. Starting Seedlings

If you want to try something new, perhaps you are tired of paper bags and others for starting your seedlings; broken eggshells can be good alternatives.

9. Pesticides

Eggshells will not kill pests in your garden, but they can certainly deter them. The abrasive feeling of broken eggshells is not welcoming for soft-bodied pests like snails and slugs. Thus, you can wave pests goodbye by sprinkling roughly ground eggshells in your garden. This way, they chase away pests and also give your soil nutrients.

10. Candle Holders

Eggshells can make for fragile candle holders. All you need to do is make you break in a shape that can hold enough liquid, insert the wick, and fill with wax.
