The Coca-Cola Company has recently reached a major milestone in its sustainable packaging journey with the launch of its first beverage bottle (excluding caps and labels) made of 100% plant-based plastic, which The technology used in the bottle is ready for commercial production
.
The company's PlantBottle™ debuted more than a decade ago as the world's first recyclable PET plastic bottle made from up to 30% plant-based material
.
Currently, Coca-Cola has produced more than 900 plant-based plastic bottles
.
"We have been working with technology partners for many years to develop suitable technologies to manufacture 100% plant-based plastic bottles with the lowest possible carbon footprint
.
It is exciting that we have been successful and can be used by players in the value chain expand
," said Nancy Quan, chief technology and innovation officer at The Coca-Cola Company
.
PET is the most recycled plastic in the world and consists of two molecules: approximately 30% monoethylene glycol (MEG) and 70% terephthalic acid (PTA)
.
The original PlantBottle™ was launched in 2009 and included MEG from sugar cane, but so far PTA has been from oil-based sources
.
PlantBottle™ packaging looks, functions and recycles similarly to conventional PET, but with less impact on the planet and its resources
.
Coca-Cola's new plant-based plastic bottle is made from plant-based paraxylene (bPX) - which can be converted into plant-based terephthalic acid (bPTA) through Virent's new process
.
As the first beverage packaging material made from bPX produced at a demonstration scale, this new technology marks a major breakthrough in the feasibility of commercial production of biomaterials
.
The bottle's bPX is produced from corn sugar while allowing some flexibility in the choice of raw materials
.
The second breakthrough technology, jointly owned by The Coca-Cola Company and Changchun Meihe Technology Development Co.
, Ltd.
, simplifies the production process of bMEG and allows flexibility in raw materials, which means more types of renewable materials can be used
.
Typically, bMEG is produced by converting sugarcane or corn into bioethanol as an intermediate and then into bioethylene glycol
.
Now, the sugar source can directly produce MEG, and the process is simpler
.
UPM is currently the first licensee of the technology and is currently building a full-scale commercial facility in Germany that will convert certified, sustainably sourced hardwood feedstock from sawmills and other wood industry by-products into bMEG
.
This marks an important milestone in the commercialization of the technology
.
Dana Breed, Global R&D Director, Packaging and Sustainability, The Coca-Cola Company, said: "The inherent challenge of using bioethanol is competing with fuels
.
We need a next-generation MEG solution that can meet this challenge, And there is also a need for a solution that can use second-generation feedstocks such as forestry waste or agricultural by-products
.
Our goal with plant-based PET is to use surplus agricultural products to minimise our carbon footprint, so the business that partners bring The combination of chemical technologies is a perfect fit for this strategy
.
”
In 2015, Coca-Cola unveiled its first 100% Bio-Based Plant Bottle™ prototype at Expo Milano, using a lab-scale production method to produce bPX
.
However, a new generation of 100% plant-based bottles already uses new technologies to produce the biochemicals needed for manufacturing and are ready for commercial production
.
“Our goal is to develop sustainable solutions for the entire industry,” Breed said.
“We want other companies to join us and move forward together
.
We don’t see renewable or recyclable content as an area where we want to gain a competitive advantage.
.
"
Since introducing PlantBottle™, Coca-Cola has allowed non-competing companies to use the technology and brand in their products — from Heinz ketchup to the fabric lining of the Ford Fusion hybrid
.
In 2018, the company opened up its PlantBottle™ IP more broadly to competitors in the beverage industry to expand demand and drive down prices
.
As part of its "World Without Waste" vision, Coca-Cola is working to make all of its packaging more sustainable, including maximizing the use of recyclable and renewable materials while minimizing the use of virgin fossil materials
.
The company has pledged to recycle the equivalent of every bottle it sells by 2030, so that its packaging doesn't become waste and old bottles are recycled into new bottles; making its packaging 100% recyclable Recycle; ensure 50% of packaging material comes from recycled materials
.
The Coca-Cola Company has announced that by 2025, it will reduce the use of petrochemical-based virgin plastics by 3 million tons
.
During the period, companies will achieve these 20 by investing in new recycling technologies such as enhanced recycling, packaging improvements (such as lightweighting), alternative business models (such as refills, dispensing and fountain systems), and the development of new renewable materials % cut
.
In Europe and Japan, Coca-Cola and its bottling partners aim to use only recycled or renewable materials and no petrochemical-based PET virgin plastic by 2030
.
While most plastic packaging material will come from mechanical recycling, some "virgin" material will still be required to maintain quality standards
.
That's why Coca-Cola is investing in and driving innovation to improve feedstock availability for renewable technologies and enhanced recycling technologies
.
Enhanced recycling "upgrades" from any quality PET plastic previously used to high-quality, food-grade PET
