Eggshells are often tossed as waste, but they’re surprisingly useful. Instead of clogging sinks or smelling in the trash, repurpose them in eco-friendly ways. Crushed shells enrich garden soil with calcium, deter pests, and enhance compost.
In the kitchen, they mellow bitter coffee, scrub pans, and clean stained mugs. Try them in crafts, seed starters, or mini planters. Feed them back to chickens, sharpen blender blades, or even add to homemade toothpaste. They help with skin irritation and make great science experiments. From the garden to DIY hacks, eggshells are more than waste—they’re a small, powerful tool with big potential.
