Move to greener plastic soda bottles could be long way off

The war for supremacy between Coke and Pepsi has taken an environmental turn with each racing to be the first to produce bottles made from plants

Over their decades of competition, the battle between Coca-Cola and PepsiCo has taken on many colors — brown (cola), orange (juice), blue (sport drinks) and clear (water).

Now, they are fighting over green: The beverage rivals are racing to become the first to produce a plastic soda bottle made entirely from plants.

But despite dueling announcements claiming technological breakthroughs, consumers should not expect to see many all-plant bottles on store shelves any time soon. Neither company is confident enough in the technology to say when, or even if, they will be able to deliver on their environmental ambitions.

Coke delivered the latest volley on Thursday last week, saying it plans to work with three companies that are developing competing technologies to make plastic from plants, with bottles rolling out to consumers in perhaps a few years.

PepsiCo is aiming to beat that timeline and claim the 100 percent green label first. The company declared in March that it had cracked the code of the all-plant plastic bottle, and on Thursday, it said that it was on schedule to conduct a test next year that involved producing 200,000 bottles made from plant-only plastic.

But until Pepsi conducts the test, executives said they would not be able to predict when large-scale production of such bottles might begin. If the test fails to prove that the technologies favored by Pepsi are cost-effective at a commercial scale, more experimentation will be needed, said Denise Lefebvre, the company’s vice president for global beverage packaging.

“The test is very important in really determining efficient cost and manufacturing processes,” Lefebvre said. She said the company was still working out details of the test, including what products to sell in the all-plant bottles and what type of plant materials to use to produce them.

Coke was the first out of the gate in the green bottle race, when in 2009 it began selling Dasani water in the US in bottles made with up to 30 percent plant-based plastics. (In some cases, recycled plastic may decrease the plant-based amount.)

On Thursday the company said that by 2020 all of its plastic bottles would meet the 30 percent plant-based standard.

But the company was more cautious about when it could start selling beverages in bottles made entirely from plant materials. “We will set the target once we have the commercial technology in place,” said Scott Vitters, the general manager of Coke’s plant bottle packaging platform.

One of Coke’s new partners, Virent, a Wisconsin-based biofuel and chemical company partly owned by Cargill, Shell and Honda, said it hoped to have a large-scale plant to produce plastic for beverage bottles up and running in 2015.

Vitters would say only that some commercial production of 100 percent plant-based plastic bottles was achievable “in the next few years.” The exception is Coke’s Odwalla juice brand, which already uses all plant-based material to make a type of plastic suitable for juices.

The two other companies working with Coke to develop the all-plant soda bottles are Gevo and Avantium.

Lefebvre said that Pepsi was following a similar path to the one Coke announced Thursday, teaming up with companies that are developing different ways of solving the plastic puzzle. But she declined to identify the partners.
