The Coca-Cola Company unveiled the world’s first PET plastic bottle made entirely out of plant-based materials at the World Expo in Milan this week.

Named PlantBottle, the company said the packaging is a way for it to stay within its vison of developing a more responsible plant-based alternative to packaging which has traditionally been made from fossil fuels and other non-renewable sources.

According to Coke, the patented technology converts natural sugars found in plants—specifically sugarcane and waste from the sugarcane manufacturing process—into the ingredients needed to make the bottles.

“Today is a pioneering milestone within our Company’s packaging portfolio,” said Nancy Quan, global research and development officer for Coca-Cola. “Our vision was to maximize game-changing technology, using responsibly sourced plant-based materials to create the globe’s first fully recyclable PET plastic bottle made entirely from renewable materials. We are delighted to unveil the first bottles here at World Expo - a world-class exhibition where sustainable innovation is celebrated.”

 In addition to coming in a variety of sizes, Coke says the package will have applications across water, sparkling, juice and tea beverage brands.
