TED talk: Are mushrooms the new plastic?
In July, Eben Bayer gave a speech at an Oxford TED conference detailing how his company turns agricultural waste into truly biodegradable packing material. How biodegradable? It's literally grown from a fungus.
Polystyrene (or styrofoam, as many know it) is commonly used to pack delicate hardware and breakables for shipping; When it degrades in nature, it releases carcinogens. If adopted for widespread use, Bayer's packing material could reduce the production and disposal of polystyrene immensely.
