You've probably seen the heart-wrenching photos of the damage plastic six-pack rings can do to marine life. They tangle the wings of sea birds, choke seals and warp the shells of growing sea turtles. A Florida brewery has a solution: six-pack rings that that can either biodegrade or serve as a snack for wildlife. After years of research and development, the rings - made of wheat and barley - are now popping up in south Florida stores. Saltwater Brewery, a craft microbrewery in Delray Beach, developed the rings with a startup called E6PR. Troubleshooting and manufacturing the rings was expensive. E6PR hopes other breweries - both small and large - will buy into the new rings and help bring costs down.
