Sustainability Hacks | Eggshells

Washington (GGM) Analysis | May 4, 2021 by author & climate journalist Noreen Wise

Sustainability is vitally important in our quest to lower our carbon footprints and preserve our natural resources for future generations. Improving the outcome of our sustainable living strategies involves a lot of critical thinking, ingenuity, and resourcefulness, three valuable life skills, that once acquired, consistently power us through the many tough challenges we’ll likely face across the decades. These life skills are yet another residual benefit bestowed on us from living sustainably.

Many or our international allies are well on their way to fully transitioning to a sustainable national culture, with the vast majority of citizens already immersed in refuse-reuse-recycle, as well as weekly curbside compost pick-up, growing their own food, gifts wrapped in cloth and tied with a reusable ribbons, upcycled treasures, etc. I was wowed by the good fortune of spending nine months in Canada during the worst of covid, living this idyllic dream culture that some refer to as Utopia. This eco-friendly lifestyle is refreshingly invigorating. I was amazed at how happy Canadians are, much happier than most Americans. The positive, upbeat vibe seemed to be one of the many beneficial side effects of sustainability. The personal well-being impact became a powerful motivator for me to stay the course when I returned to Virginia.

Heart of the matter. The devil is in the details. Now that I’m back, with this whole new perspective, I was jazzed to discover a fabulous sustainability subculture in the United States, thriving in its simplicity and vitality. Many of these eco-innovators are eager to share tips they hope will inspire others  to commit to this climate necessity transformation. One particular woman is Rose Tenaglia Dunn, who lives on cape Cod. Rose is the host of the very popular Eaarth Feels podcast, which I highly recommend.

Rose provided tips for simple and easy ways to reuse the eggshells that are daily staples in most households. She’s been using eggshells regularly for eight years:

  • Throw the eggshells into a jug and add water. Rose calls this “eggshell tea,” one of her dad’s gardening hacks. He would use the tea to water the house plants which Rose marveled were always “healthy and lush.” But, the tea is stinky, so you may want to store in the garage or outside.
  • Rinse the eggshells and store in a carton under the sink. Once the carton is full, transfer the eggshells to a bag and crush them until they’re “miniscule.” Rose uses a rolling pin. Feel free to be resourceful and use whatever you have at your disposal. Because eggshells are rich in calcium and protein, Rose uses the crushed shells as a toxin-free fertilizer and sprinkles them on the vegetables in her garden, particularly: tomatoes, spinach, eggplant, peppers, and Swiss chard.
  • Eggshells can be used as tiny seed pots, and Rose is currently experimenting with this. She just planted pepper and corn seeds in the eggshells and will transfer the little glob directly into the vegetable bed once the seeds have sprouted and grown (about 3 to 4 inches and have their second set of leaves). Rose explains that the eggshell will serve as the fertilizer.

See what I mean about ingenuity and resourcefulness? Tasking children to help think of clever, beneficial ways to use “stuff” that would otherwise become waste will help develop these often dormant life skills. 

Next steps:

  • Our food system is a great place to begin the deep dive into sustainability.
  • If you’re not already composting kitchen scraps, you may want to start here. It’s a wonderful launching point that will have immediate benefits.
  • Eliminate all products packaged in plastic, which are usually condiments like ketchup, and many bottled drinks, etc.
  • Replace the plastic personal care products (tooth brush, toothpaste, shampoo, conditioner, switching to bamboo or bars).
  • Make sure you have non-plastic reusable water bottle and coffee mug for Starbucks visits.
  • And so many more ideas. The list is endless really.

Becoming 100 percent sustainable is a long and winding road. It will take time. But starting the journey is very simple and quick. You can gain today by rinsing a carton as well as today’s  eggshells and placing them under your sink. Good luck and have fun with each new discovery.
