An interesting idea from a small American Brewery:

Most of these plastic six-pack rings end up in our oceans and pose a serious threat to wildlife. Together with Saltwater Brewery, a small craft beer brand in Florida whose primary target are surfers fishermen and people who love the sea, we decided to tackle the issue head on and make a statement for the whole beer industry to follow. We ideated, designed, prototyped and manufactured Edible Six Pack Rings. A six-pack packaging design that instead of killing animals, feeds them.
