We’ve known for decades that our fondness for Ziploc bags, food wrappers and other plastics is hurting the environment—particularly sea life. But both consumers and businesses have proven largely unwilling to sacrifice the convenience of single-use plastics. Now one Florida brewing company says it’s found a way to take the guilt out of at least one common form of plastic waste. Last month, Saltwater Brewery introduced new, eco-friendly six-pack rings for their beer, a project developed in conjunction with New York ad agency We Believers. The grain-based rings are both biodegradable and edible—so rather than choking on them, marine life can safely chow down on them instead.
