Simply EGG-genious: Students invent edible packaging from eggshells
Ready-made meals are ideal for quickly satisfying hunger. However, the quick snacks produce a lot of environmentally harmful plastic waste. To tackle this problem, the student team EDGGY from the University of Hohenheim in Stuttgart rolled up its sleeves and developed edible packaging made from eggshells and other plant-based raw materials. And even better: they simply dissolve in the hot water and can be eaten as an additional protein boost.
