Eggshells are often discarded as kitchen waste, but they have a multitude of uses that can benefit both your home and garden. Here are 11 ingenious ways to repurpose eggshells, turning waste into a valuable resource.
1. Natural Fertilizer
Eggshells are rich in calcium, making them an excellent natural fertilizer. Crush them into small pieces and sprinkle them around your garden to enrich the soil and promote healthy plant growth.
2. Pest Deterrent
Crushed eggshells can act as a natural pest deterrent. Scatter them around the base of plants to create a barrier against slugs and snails. The sharp edges of the shells discourage these pests from crossing.
3. Compost Enrichment
Add eggshells to your compost pile to boost its calcium content. The shells decompose and release valuable nutrients, helping to create richer, more fertile compost.
4. Seed Starters
Eggshell halves make perfect biodegradable seed starters. Fill them with soil, plant your seeds, and place them in a sunny spot. Once the seedlings are ready to transplant, you can plant the entire shell, which will decompose and nourish the soil.
5. Soil Aeration
Mix crushed eggshells into the soil to improve aeration and drainage. This helps roots grow more effectively and prevents waterlogging.
6. Bird Feed
Birds need calcium for egg production, and ground eggshells can be a great supplement. Sterilize the shells by baking them at 250°F (120°C) for about 10 minutes, then crush them into fine pieces and add them to your bird feeder.
7. Cleaning Agent
Eggshells can be used as a gentle abrasive cleaner. Mix crushed eggshells with a bit of soapy water to scrub pots, pans, and other kitchen utensils without scratching them.
