The brewery said the rings are made from byproducts of the brewing process and are completely biodegradable.
"Most plastic beer six‐pack rings end up in our oceans and pose a serious threat to wildlife," the brewery said in a Facebook post. "Together with We Believers, we ideated, designed, tested and prototyped the first ever Edible Six Pack Rings. A six‐pack packaging, made with byproducts of the beer-making process, that instead of killing animals, feeds them. They are also 100% biodegradable and compostable. We hope the big guys follow."
