In 2022, industry leaders ExxonMobil, Cyclyx Intl., Sealed Air, and Ahold Delhaize USA announced the intention to be successful US launch of a circular food packaging proof-of-concept leveraging advanced recycling. During a successful demo, plastic waste was collected from grocery stores, diverting it from landfills.
Following a viable test, the advanced recycling process that leverages ExxonMobil’s Exxtend technology for is now being evaluated for scale.
The Exxtend process breaks down plastic waste into its molecular building blocks that’s attributed through a mass-balance approach to new plastic for food-grade packaging. This collaboration demonstrated that creating a circular economy is achievable with value chain collaboration.
Creating a circular economy for food contact plastic packaging in applications where there are strict safety and performance requirements is a difficult challenge facing the industry.
“This project helps demonstrate how Exxtend technology can widen the range of plastic materials that can be recycled while delivering certified-circular polymers with the critical performance attributes of virgin plastic,” says Dan Moore, vice president, polyethylene, ExxonMobil. “Advanced recycling is making the impossible possible and is an important enabler to support a circular economy.”
Plastic waste for recycling was collected at select Food Lion store locations.
Ahold Delhaize USA brand Food Lion supported the initial pilot, collecting plastic waste for recycling at select store locations. With more than 1,100 stores across 10 states, Food Lion is one of the five brands that comprise the Ahold Delhaize USA network — the largest grocery retail group on the East Coast and the fourth largest in the nation.
“Across Ahold Delhaize USA companies, we have ambitious goals around recyclable and reusable packaging,” says Adam Springer, manager, product sustainability, Ahold Delhaize USA. “Based on the initial pilot, we’re optimistic about being able to leverage this process at additional scale and look forward to exploring it further as part of this collaboration.”
Cyclyx, a joint venture between Agilyx Corporation and ExxonMobil, was responsible for sorting and pre-processing the waste packaging materials collected from the Food Lion stores, before delivering them to ExxonMobil’s Baytown, TX, facility.
“The interface between the Food Lion stores and the Baytown facility was critical and required an innovative approach to feedstock management,” says Joe Vaillancourt, CEO, Cyclyx. “Part of our process is to identify the chemical composition of the waste plastics we receive. This allows us to create custom blends of post-use plastic feedstock that are tailored to the specifications required for advanced recycling.”
At the Baytown facility, Exxtend technology for advanced recycling is used to recycle the valuable end of life plastics and attribute them via mass balance accounting to certified-circular polymers.
The resulting polyethylene polymers' performance have the characteristics of virgin resins.
“The technology provides a reliable source to attribute to high-performance, certified-circular polymers,” Moore says. “The resulting polymers, such as Exceed S, Exceed XP, Exceed and Enable performance polyethylene (PE), have the characteristics of virgin resins, which is critical for food-grade packaging.”
Sealed Air, which is designing and creating high-performance packaging materials that can be remade, converts the certified-circular PE resins into food-grade flexible film that is used, in the case of this proof of concept, to package select Nature’s Promise fresh poultry. The packaging then returns to stores used on products purchased by customers, demonstrating an example of the circular economy.
“By collaborating with suppliers and customers, we were able to identify, design, and commercialize an innovative flexible packaging solution which supports circularity,” says Ron Cotterman, vice president, global corporate affairs, Sealed Air.
To help meet the growing market demand for certified-circular plastics, ExxonMobil plans to increase its annual advanced recycling capacity to 500,000 metric tons, or approximately 1 billion pounds, by year-end 2026 across multiple sites globally.
