For over a decade, establishing a clear definition of sustainable packaging posed a challenge in the industry. However, thanks to the Global Commitment, a common framework has emerged. Launched in 2018 by the Ellen MacArthur Foundation and the United Nations Environment Programme, this initiative has brought together more than 1,000 organizations and 55 countries, with 250-plus companies representing 20% of global plastic packaging.

The Commitment delineates a path to initiate systemic change in the entire plastic economy, ensuring sustainability in packaging. Signatory companies and governments pledge, with standardized metrics, to make 100% of plastic packaging reusable, recyclable or compostable by 2025. Their objectives include increasing postconsumer recycled content, reducing virgin plastic use, adopting reuse models and collaborating to enhance the circularity of plastic packaging.

As the commitment hits the five-year mark, we delve into the accomplishments, persisting challenges and insights gleaned from those actively involved.

Advancements and Ongoing Challenges

The Global Commitment envisions a circular plastic economy where plastic never becomes waste. Thais Vojvodic, manager of the Plastics Initiative at the Ellen MacArthur Foundation, emphasizes that the commitment has introduced unprecedented transparency to companies’ plastic footprints, generating standardized, publicly accessible data. This shared vision and language have transcended borders, with 11 Plastic Pacts globally adopting similar approaches.

A notable success is the doubling of recycled content in packaging by Commitment signatories, reaching a total of 1.5 million tons annually. This achievement equates to avoiding the extraction of one barrel of oil every two seconds — a significant milestone. Moreover, participating recycling companies boosted their postconsumer recycled plastic production by 90%, surpassing the market average of around 25%.

Despite these considerable strides, the Global Commitment has identified three fundamental areas for improvement: transitioning to reusable models, finding recyclable solutions for flexible packaging, and establishing collection and recycling infrastructures supported by extended producer responsibility policies. Vojvodic underscores the urgency of addressing these areas, as only a switch to reuse/refill strategy could have the potential to reduce ocean plastic pollution by over 20% by 2040.

Graham Packaging Co., a leading plastic packaging manufacturer headquartered in Lancaster, Pennsylvania, has evolved from producing motor oil containers in 1970 to a global player attracting Fortune 500 clients and independent businesses alike. Operating plants across North America, Europe and South America, it annually manufactures millions of plastic bottles.

According to Richa Desai, vice president of sustainability, Graham Packaging is dedicated to advancing sustainable solutions and fostering a circular economy for rigid plastics. Its goal is to achieve 100% recyclability for the entire product range by 2025, focusing on the pillars of stop using nonrecyclable products, eliminate nonrecyclable items, and improve with redesign as part of its strategy.

To boost the use of postconsumer recycled (PCR) materials, Graham employs strategies such as operating the Graham Recycling Center (GRC) in York, Pennsylvania, processing over 33 million pounds of #2 HDPE bottles into PCR annually. Additionally, it actively sources PCR from diverse channels, from both mechanical and advances recycling, providing flexibility to customers in achieving voluntary and mandatory sustainability goals. It has obtained ISCC Plus and RMS certifications for traceability.

Graham aims to achieve an average of 20% PCR in its product portfolio by 2025. It recommends PET, HDPE and Polypropylene to customers for their recyclability. To address the 2% that is challenging to recycle, it is collaborating with the National Lubricant Container Recycling Coalition to establish a recycling system for lubricant bottles and working to eliminate the remaining PVC from product lines by 2025.

In 2022, Graham received the Dow Packaging Innovation Silver Award for redesigning Danone’s Danacol yogurt bottle, reducing annual plastic use by 286,600 pounds through label-less design.

In a strategic move to reduce virgin plastic use, Graham invests in lightweighting solutions such as AccuStrength and Active Base. AccuStrength utilizes vertical bands of plastic material that can be adjusted to increase or decrease a bottle’s thickness in a desired location. This technology can maintain or improve a container’s performance while reducing the amount of plastic used.

In fact, AccuStrength’s technology has produced containers that are up to 11% lighter than traditional horizontal-banded bottles while remaining 100% recyclable. On the other hand, Active Base enables the base of the bottle to flex during the fill process and respond to changes in the pressure of the container while cooling. This technology comes in two forms: self-activating base (SAB) and mechanically activating base (MAB). Both technologies offer increased design freedom, while MAB reduces resin weight, producing containers that are at least 20% lighter than existing hot-fill market alternatives and enables the use of up to 100% PCR content.

In the reuse/refill realm, Graham’s REFPET reusable bottles, produced only in Mexico, experience up to 25 reuse cycles, because of a patented bubble texture. Recognized by the Sustainable Packaging Coalition in 2020, these bottles showcase a 47% longer reuse cycle compared to previous generations.

Cross-Sector Collaboration: A Crucial Catalyst for Change

In the past five years, positive strides have been made in plastic sustainability initiatives. However, Thais Vojvodic, of the Ellen MacArthur Foundation, pointed out that the world is still far from solving the problem. At least 80% of the plastic packaging industry is not part of the Global Commitment, and these companies significantly underperform compared to the 20% that signs it. She emphasizes that future progress hinges significantly on political interventions, especially through policies like Extended Producer Responsibility (EPR). She notes, “EPR has proven to make recycling economically viable, offering transparency, efficiency and incentives for upstream solutions such as improved packaging design and reuse.”

Vojvodic underscores the vital role of collaboration among businesses, government policies, and society at large to propel the journey toward a circular and sustainable plastic economy. This call to action is particularly directed at engineers and professionals in training, emphasizing their pivotal role in crafting innovative solutions to contribute to this global crusade and achieve collective goals on a global scale.
