If eggshells end up in the trash after breakfast, it's time to reconsider this habit. These fragile residues are not just waste, but a natural source of calcium and a mild abrasive that is useful in the kitchen, in the garden, and even in personal care.
What can you do with eggshells:
1. Fertilizer for plants
Grind the dry shells into powder and add to the ground when planting tomatoes, peppers, and cabbage. Calcium strengthens stems, prevents blossom end rot and improves yield.
2. Soft scrub for face or hands
Mix finely ground shells with honey or yogurt. The particles gently exfoliate while the calcium strengthens the skin. Ideal for sensitive skin.
3. Cleaning thermoses and bottles
Place a handful of crushed shells in a container, add warm water and shake. The shell gently removes plaque and odor without scratching the glass.
4. Repeller for slugs and snails
Scatter coarsely crushed shells around the beds. Sharp edges repel pests; they do not like to crawl on such a surface.
5. Compost additive
The shells enrich the compost with calcium and accelerate the decomposition of organic matter.
How to store
Rinse the shell, dry it on a radiator or in the oven at 50°C. Grind in a mortar, coffee grinder or mortar. Store in a dry glass jar with a tight lid for up to 6 months.
This approach not only reduces the amount of waste, but also returns value to what we used to think of as trash. It also saves money on fertilizers, scrubs and cleaning products.
