Researchers working for industrial development company Carbios have created a mutant bacterial enzyme that can break down plastic bottles for recycling in only a couple of hours, according to The Guardian.
The enyzme can break down PET plastic bottles into their individual chemical composites, which could later be reused to make brand new bottles.
Conventional recycled plastic that goes through a “thermomechanical” process isn’t high enough quality and is mostly used for other products such as clothing and carpets.
Carbios partnered with major industry leaders including Pepsi and L’Oreal to help develop the technology. A scientific paper describing the discovery was published in the prestigious journal Nature today.
The “PET hydrolase” enzyme can break down 90 percent of PET polymers in just ten hours.
“This highly efficient, optimized enzyme outperforms all PET hydrolases reported so far,” reads the paper’s abstract – even in comparison to the second most promising candidate, a plastic-degrading bacterium strain called 201-F6.
The new enzyme was first spotted in a heap of composted leaves back in 2012.
“It had been completely forgotten, but it turned out to be the best,” Alain Marty at the Université de Toulouse, France and the chief science officer at Carbios, told The Guardian.
The new enyzme was also extremely cost effective to produce. In fact, according to the researchers, making new plastic from oil would have cost 25 times as much.
“It’s a real breakthrough in the recycling and manufacturing of PET,” said Saleh Jabarin, professor at The University of Toledo, Ohio and a member of Carbios’ Scientific Committee, in a statement.
The researchers are hoping to test the material’s “industrial and commercial potential” in 2021 in France, according to Marty. “Our goal is to be up and running by 2024, 2025, at large industrial scale,” deputy chief executive at Carbios Martin Stephan told The Guardian.

Beatrix Farrand’s American Landscapes, follows award-winning public garden designer Lynden B. Miller as she sets off to explore the remarkable life and career of America’s first female landscape architect—Beatrix Farrand. Farrand was responsible for some of the most celebrated gardens in the United States and helped create a distinctive American voice in landscape architecture. Although she created gardens for the rich and powerful, including John D. Rockefeller, Jr., J.P. Morgan, and President Woodrow Wilson, she also was an early advocate for the value of public gardens and believed strongly in the power of the natural world to make people’s lives better. Through the documentary, Miller journeys to iconic Farrand gardens, engaging designers, scholars and horticulturists in a spirited dialogue about the meaning and importance of this ground-breaking early 20th-century woman. Lynden Miller’s experience as New York City’s most prominent public garden designer is woven into a wide-ranging biography of Farrand’s life and times.
Starring Piet Oudolf; 75 minutes; Presented with Captions for the hearing impaired.
Director Thomas Piper filmed the garden designer Piet Oudolf over five seasons as he designed gardens from New York’s High Line and Hauser and Wirth’s prairie garden in Somerset, England to his own private garden at Hummelo in Holland.
Five Seasons: The Gardens of Piet Oudolf is an immersive and meditative documentary that reveals how the revolutionary landscape designer,Piet Oudolf, upends our conventional notions of nature, public space, and, ultimately, beauty itself.
