With the rise of 4-packs came a rise in rings. Thankfully most breweries are not using the translucent ocean killers as in years past but I still have a major league stack of the plastic snap ons and only one brewery that I know of that takes them back.
But now comes the Craft-Pak Versa can carriers. They “use up to 50% less plastic than competitor carriers without compromising form or function. Plus, certified 100% biodegradable*, Craft-Pak Versa completely decomposes within months. This produces fewer emissions and creates less waste.”
I am hoping to see more of these on the market.
