Saltwater Brewery was a regular microbrewery that made great craft beer - packaged with the usual plastic six pack rings. As fishermen who saw firsthand the amount of plastic pollution in the ocean, though, they felt they needed to make a change to help marine animals. They came up with the idea to create edible six pack rings made of biodegradable materials left over from the brewing process. Now, they’ve created a new company, E6PR, to sell their “Eco Six Pack Rings” to other companies like Corona that want to help clean up the oceans and improve their sustainability.
