The potential to endlessly recycle PET plastic recently became a step closer to reality, as
a consortium of companies dedicated to the cause —
Carbios,
L’Oréal, Nestlé
Waters,
PepsiCo and Suntory Beverage &
Food Europe — announced the
successful production of the world’s first food-grade PET plastic bottles
produced entirely from enzymatically recycled plastic.
Each participating company has successfully manufactured sample bottles — based
on Carbios’ enzymatic PET recycling technology — for leading products including
Biotherm, Perrier, Pepsi Max (aka Pepsi Black and Pepsi Zero
Sugar in some markets) and Orangina.
The breakthrough is the culmination of nearly 10 years’ research and development
by Carbios — a French company pioneering bio-industrial solutions to reinvent
the lifecycle of plastic and textile polymers — which developed a process to
supercharge an enzyme naturally occurring in compost heaps that normally breaks
down leaf membranes of dead plants. By adapting this enzyme, Carbios has
fine-tuned the technology and optimized it to break down any kind of PET plastic
(regardless of color or complexity) into its building blocks, which can then be
turned back into like-new, virgin-quality plastic.
As Carbios CEO Jean Claude Lumaret explains:
Circularity by Design: How to Influence Sustainable Consumer Behaviors
Join us Thursday, December 5, at 1pm ET for a free webinar on making circular behaviors the easy choice! Nudge & behavioral design expert Sille Krukow will explore the power of Consumer Behavior Design to drive circular decision-making and encourage behaviors including recycling and using take-back services. She will share key insights on consumer psychology, behavior design related to in-store and on-pack experiences, and how small changes in the environment can help make it easy for consumers to choose circularity.
“In a world first, we have created food-grade clear bottles from enzymatically
recycled, colored and complex plastic with identical properties to virgin PET.
And in partnership with the Consortium, we have proved the viability of the
technology with the world’s leading brands. This is a truly transformational
innovation that could finally fully close the loop on PET plastic supply
globally, so that it never becomes waste.”
Carbios’ patented enzymatic PET-recycling process enables a wide variety of PET
plastics to be recycled into virgin-quality, food-grade rPET. PET plastics that
would otherwise go to waste or be incinerated can now be brought back into a
continuous circular system of recycling. And this can be achieved at high speed
— breaking down 97 percent of plastic in just 16 hours — 10,000 times more
efficient than any biological plastic recycling trial to date, according to a
peer-reviewed article in
Nature.
Together, these brands will work to scale this innovation to help meet the
global demand for sustainable packaging solutions. In September 2021, Carbios
will break ground on a demonstration plant, before launching a 40,000 tons
capacity industrial facility, by 2025. Carbios plans to license the technology
to PET manufacturers worldwide, accelerating the global adoption of enzymatic
recycling for all kinds of PET-based products — which, at scale, would
definitely be a boon to, for example, the US Plastics Pact and its goal for
the country to achieve a circular economy for plastics in the next four
years.
In 2017, Carbios and L’Oréal founded a
consortium
to bring Carbios’ enhanced recycling technology to market on an industrial
scale. Nestlé Waters, PepsiCo and Suntory Europe signed on in
2019 to
help further drive the circular innovation.
“We have been working with Carbios since 2017 to develop this first bottle made
from PET derived from enzymatic recycling technology, an alternative to
mechanical recycling,” said Jacques Playe, L’Oréal’s Global Head of
Packaging and Product Development. “We are pleased to announce the feasibility
of these bottles in a pilot phase and are delighted to be in a position to
create the packaging of the future with our partners. This is a promising
innovation for the years to come that demonstrates our commitment to bring to
market more environmentally friendly packaging and which is part of a
circularity initiative begun more than 15 years ago.”
Enzymatic recycling overcomes the issue of degradation in conventional recycling
and can be used on any type of PET plastic. Because Carbios’ recycling process
works under mild conditions, it could also lower the carbon footprint of PET
waste treatment by saving 30 percent of CO2 emissions compared to a conventional
end-of-life mix of incineration and landfill, taking virgin PET production
substitution into account.*
The successful completion of these initial food-grade bottles is a major
milestone in the consortium’s validation of Carbios’ technology. This
partnership is part of a growing trend amongst brands to collaborate across
industries to tackle these global challenges, working towards a world of
circularity, where we limit the production of virgin plastic and eliminate
plastic pollution from the environment.
“The global issue of plastic waste requires transformational thinking, creative
partnerships and innovative brands coming together to seek out new solutions,”
said Roberto Vanin, Chief R&D Officer at Suntory Beverage & Food Europe.
“Continued investment in new ways of tackling waste and creating true
circularity such as this groundbreaking technology from Carbios will be key to
Suntory Beverage & Food Europe achieving its 100 percent sustainable plastic
ambition.”
