ATLANTA \u2014 Leaders of Coca-Cola Co., the world’s largest user of PET, have a goal of using 100 percent plant-based resin in all its PET bottles, a top Coke researcher said at the Society of Plastics Engineers Annual Blow Molding Conference.<\/p>\n
Yu Shi, director of next-generation materials and sustainability, said sales of the most-visible PlantBottle, Dasani water, have increased by 20 percent thanks to the green packaging. Coke rolled out PlantBottle in 2009.<\/p>\n
“Our water brand, ever since we launched the Dasani, in the PlantBottle, it has continued to grow,” she said.<\/p>\n
Shi was the luncheon speaker at the SPE conference in Atlanta \u2014 Coke’s hometown \u2014 on Oct. 8.<\/p>\n
She said the PlantBottle version has about 30 percent PET resin from sugar cane and 70 percent bio-based purified terephthalic acid, or PTA.<\/p>\n
The bottles, now used in 27 countries, are fully recyclable.<\/p>\n
The next horizon may be PEF, polyethylene furanoate, a bio-based alternative to PET. Coke is working with Avantium, a renewable chemicals firm based in Amsterdam on bottles from PEF, which Shi said “has the promise of barrier” properties.<\/p>\n
One big issue is how will PEF impact the recycling stream, the Coke executive said at the blow molding conference. Coke is a major user of recycled PET, and the company doesn’t want to damage its own recycled material.<\/p>\n
Coke is part of the PlantBottle Technology Collaborative, which includes Ford Motor Co., H.J. Heinz Co., Nike Inc. and Procter & Gamble Co.<\/p>\n","protected":false},"excerpt":{"rendered":"
