Cracking the Case: Can Eggshells be Composted? Unveiling the Truth Behind Eggshell Composting

Can Eggshells Be Composted?

In recent years, more and more people have been embracing the idea of composting as a sustainable way to reduce waste and improve soil health. Composting involves breaking down organic materials into nutrient-rich humus that can be used to fertilize plants. While many kitchen scraps like fruit peels and coffee grounds are commonly added to compost piles, there is often confusion about whether eggshells can be composted. In this blog post, we will explore the benefits of composting eggshells, how to prepare them for composting, and some common misconceptions surrounding this topic.

The Benefits of Composting Eggshells

Eggshells are not only an excellent source of calcium but also contain trace amounts of other minerals essential for plant growth such as magnesium and phosphorus. When these shells break down in a compost pile or bin, they release these valuable nutrients into the soil over time.

Additionally, eggshells help to balance the pH levels in acidic soils due to their alkaline nature. This is particularly beneficial for plants that prefer neutral or slightly alkaline conditions.

Preparing Eggshells for Composting

Before adding eggshells to your compost pile or bin, it’s important to prepare them properly:

  1. Rinse: Rinse any remaining egg whites from the shells with cool water immediately after using eggs in cooking or baking.
  2. Dry: Allow the rinsed shells to air dry completely before placing them in your compost container. Drying helps prevent any unpleasant odors during decomposition.
  3. Crush: Crush the dried shells into smaller pieces using a mortar and pestle or by wrapping them in a clean cloth and gently tapping with a rolling pin. Crushing the shells increases their surface area, helping them break down faster in the compost pile.

Remember, it’s important to only compost eggshells from eggs that have been cooked or used for baking. Raw eggshells may contain harmful bacteria, so it’s best to discard them instead of adding them to your compost.

Common Misconceptions about Composting Eggshells

There are a few misconceptions surrounding the composting of eggshells:

  1. Deteriorating garden snail population: Some people avoid composting eggshells due to concerns about attracting garden snails. However, research suggests that properly crushed and incorporated eggshells do not significantly increase snail populations.
  2. Increase in pests: Another concern is that composting eggshells may attract unwanted pests like rats or raccoons. This can be easily avoided by keeping your compost pile covered or using enclosed bins that prevent access to animals.
  3. Poor decomposition rate: While it is true that whole eggshells take longer to decompose fully compared to other kitchen scraps, proper preparation through rinsing, drying, and crushing significantly speeds up the process.

The Verdict: Yes, You Can Compost Egg Shells!
