Coca-Cola Trials Turning Hard-to-Recycle Plastic Into Bottles

“This new technology is critical to improve access to recycled material for bottles,” said Wouter Vermeulen, Coca-Cola’s senior director of sustainability and public policy in Europe. “The Coca-Cola system is committed to reducing our dependency on oil for producing virgin packaging materials and promoting recycling.” 

Coca-Cola is aiming to boost the proportion of recycled materials that make up its packaging to 50% by 2030. The soft-drinks group has achieved around 25% so far. 

The company needs its bottlers to use more recycled materials to meet its own sustainability goals. “We simply do not have the necessary levels [of recycled plastic],” said Joe Franses, vice president of sustainability at Coca-Cola Europacific Partners. 

The new process from startup CuRe Technology cleanses and partially breaks down plastics for reassembly into recycled material. Its so-called partial depolymerization method removes color from polyester, turning it into clear polyethylene terephthalate—or PET—pellets. A study commission by CuRe said its process results in roughly 65% lower greenhouse-gas emissions than oil-based new plastic production. Coca-Cola Europacific Partners invested in CuRe in 2020 and again this year. 

CuRe has been sending samples to Coca-Cola in Atlanta for testing and, if it continues to meet quality standards, it is possible the recycled plastic could make its way to other markets.

“We are currently focused on scaling CuRe’s technology in the right way for use in Europe as a first priority, before looking at how this could benefit other markets,” Coca-Cola’s Mr. Vermeulen said.

By 2025, a plant is expected to produce around 25,000 metric tons of recycled plastic a year. Coca-Cola Europacific Partners will get a significant amount of that output but it will represent a fraction of its feedstock, currently around 200,000 metric tons of polyester a year in Europe. If the factory meets expectations, the bottler will build a larger plant before the end of the decade.

Packaging represents around 40% of Coca-Cola Europacific Partners’ carbon footprint, largely because of its use of oil-based virgin plastic. It aims to stop using oil to produce plastic bottles by 2030. Last year, almost half of its bottles were made from recycled plastic and bioplastics.

By the turn of the next decade, Mr. Franses at Coca-Cola Europacific Partners envisions technology such as CuRe’s supplying around 25% of the bottling company’s needs while traditional recycling methods will satisfy about 70%. He hopes recycled plastic supplied by CuRe’s method to be on par or not significantly more expensive than current recycled plastic, which can be 50% more costly than plastic made from oil.

“I’m not going to stand here in 2023 and say we’ve got a full road map that is going to take us there,” Mr. Franses said. “What I am really confident on is that the business has made the right investments.”
