WEB EXCLUSIVE: PepsiCo, Purchase, N.Y., says it has developed the world’s first PET bottle made entirely from plant-based, renewable resources. This “green” bottle is chemically identical to standard PET, but it is made from biobased raw materials derived from sources such as switch grass, pine bark, and corn husks. In the future, the company expects to broaden the range of renewable sources to include orange and potato peels, oat hulls, and other agricultural byproducts of its food business. PepsiCo (pepsico.com) will pilot production of the bottle in 2012.
Up to now, biobased PET, such as Coca-Cola’s PlantBottle, has contained at most 30% renewable content—ethylene glycol derived from sugarcane ethanol. It appears that PepsiCo has found a source of the other component of PET, terephthalic acid, that is also biobased.
