It's not exactly a tasty snack, but its edible nature is testament to how safe Woamy's namesake foam is. Made from wood or agricultural waste, it can go toe-to-toe with its plastic counterpart without lingering in the environment for 500 years. There's a long way to go until Woamy can reach the same production volumes as styrofoam but a successful seed funding round and plans to scale bode well for the future.
