As you may have noticed, more and more companies are ditching single-use plastics in favor of, well, not destroying the planet we live on. The latest company to join the trend is Guinness, the beer giant from Ireland. Looks like green beer isn’t just for St. Patricks day! Diageo, the manufacture of Guinness announced they are replacing plastic beer packaging with 100 percent biodegradable or recyclable cardboard. By ditching plastic ring carriers and shrink wrap, they’ll be removing the equivalent of 40 million plastic bottles from polluting the planet—a testament to how much impact one company can have on the environment. Meanwhile, the beer brand Corona has started piloting plastic-free six-pack rings made from plant-based biodegradable fiber.
