🥗 Welcome to my garden, a lush green oasis thriving on an unexpected secret - human urine! In this video, I reveal my secret weapon for growing the greenest of gardens - Aurin, a fertilizer commercialized by VUNA, an Eawag start-up and derived from human urine.
♻️ Let's delve into why this natural nitrogen, phosphorus, and potassium source is perfect for all gardeners.
(🚽 ...and let's explore the link between our toilets and our gardens and how redesigning one can revolutionize the other.)
Does the nutrient cycle in your garden mean that soil becomes poorer over time?
That's our lucky day: our body evacuates essential nutrients through pee and poo, let's recycle them back into our gardens!
We'll swiftly look at the fascinating history of human waste as fertilizer, its benefits, and its drawbacks. And, of course, learn about Aurin, a safe and efficient fertilizer produced by Vuna, an EAWAG spin-off.
🚾 I'll explain how urine-based fertilizers are an excellent example of a circular economy done right, making you an environmental superhero while feeding your strawberries.
We'll also discuss feces management and how it differs from urine treatment. Finally, we'll look at how clever toilet design can separate urine from feces, enabling us to start our liquid fertilizer production journey.
Join me in this exploration of sustainable gardening. Let's feed our gardens, not just our bodies, and turn our waste into wealth.
