Waste equals food

This is one of the mantras in McDonough's and Braungart's Cradle to Cradle, which I finished up yesterday. In the book, they are mainly referring to the design of more intelligent manufacturing processes and materials. But this concept has a lot to offer when thinking about food waste. Compost is the ultimate cradle to cradle process. Not only does waste equal food, but food equals waste. 

Another repeated scenario in the book is the idea of product packaging that can be safely thrown on the ground to decompose or that is embedded with seeds that will grow into a tree. Extend this to food, and you could imagine a candy wrapper that grows into a tomato plant. So you can feed yourself with the food inside the packaging as well as the packaging itself.
