The Coca-Cola Co. is sharing its PlantBottle technology with H.J. Heinz Co. for use in ketchup bottles. Coca-Cola introduced the PlantBottle, which combines 30% ethanol-based polymer with 70% polyethylene terephthalate (PET), for water and carbonated soft drinks in 2009. The PlantBottle is unusual among packaging that uses bio-based material because it is fully recyclable in waste streams alongside regular PET. Heinz plans to roll out the PlantBottle for 20-ounce bottles, its most popular size, in June, with all its plastic packaging to follow eventually. The initial launch will feature the phrase “Guess What My Bottle is Made Of?” prominently on the front label, along with the PlantBottle logo.
