The question of whether eggshells belong in organic waste might seem simple, but it often leaves people unsure.
In most cases, eggshells can be safely disposed of in organic waste because they are biodegradable and compostable. However, there are a few important considerations to keep in mind.
But there are some important considerations to keep in mind.
Eggshells are primarily composed of lime, a valuable mineral that enhances compost quality. Crushing the shells into smaller pieces before disposal helps speed up decomposition and ensures even distribution in the compost.
The Salmonella Concern
According to an article by Chip, Some people worry that eggshells might transmit salmonella if added to organic waste. Experts, however, assure that the conditions in compost are generally unfavorable for pathogens to survive.
Additionally, organic waste is typically processed at high temperatures, effectively killing bacteria like salmonella.
If the eggshells come from questionable sources or spoiled eggs, disposing of them in general waste might be a safer option—especially if you’re adding organic waste to an unheated home compost pile.
Rules for waste disposal can differ by region.
In some areas, disposing of eggshells in organic waste is prohibited. Checking your local waste disposal guidelines can clarify whether eggshells are acceptable.
