Packaging has always been a balancing act. Consumer packaged goods (CPG) companies must weigh cost versus performance and market appeal versus machinability. As interest in sustainable packaging has grown, brand owners also must balance packaging circularity with price, safety, distribution requirements, material availability, and overall environmental impact. This requires a dialogue among stakeholders about packaging design, material choices, and end-of-life disposal options.
To begin this conversation, PMMI, The Association for Packaging and Processing Technologies, and AMERIPEN, the American Institute for Packaging and the Environment, have published 2023 Packaging Compass: Evaluating Trends in US Packaging Design Over the Next Decade and Implications for the Future of a Circular Packaging System. The study and accompanying infographic identify key trends in packaging design and materials and the implications of these trends on legislation and the recovery systems for consumer-packaged goods (CPG) companies.
“By releasing this deep dive into the trends driving the circular packaging system, we hope to facilitate an industry dialogue that will help close the gap between design needs and recovery needs,” says Jorge Izquierdo, vice president, market development, PMMI. Based on extensive research and analysis, the study’s goal is to spark a conversation on trends, present forecasts for the coming decade, and recognize the role of multiple stakeholders in advancing a circular packaging system.
The 10-year forecasts and materials sales projections indicate plastic packaging, particularly the flexible pouch format; recycled-content packaging, primarily paper and plastic; and compostable packaging will experience the highest demand, although the latter represents a small share of the market. Despite the disparity in usage, these three formats have the same hurdles to overcome, a lack of end-of-life recovery infrastructure as well as effective legislative and investment strategies.
A survey of 394 consumer-packaged goods brands and retailers shows:
75% use plastics in packaging;
61% use paper;
14% use glass;
13% use metal.
Projections show plastics will grow across every category, and the use of flexible film will expand at a 4-6% compound annual growth rate (CAGR), slightly above the 3-4% CAGR for plastics overall. Plastic films offer significant operational and sustainability benefits. Tensile strength delivers more protection with less material. Light weight and compact footprint reduce carbon emissions during distribution. Highly customizable materials run efficiently on filling lines and reduce overall cost and cycle time. Consumers appreciate the format’s light weight, reduced shelf space requirements, and potential for easy-opening and resealing features.
Although usage continues to grow, figures from the Recycling Partnership show only 1.9% of the U.S. population has access to flexible film recycling. Most of this film is recovered from retail drop-off programs, but consumer participation in these programs is low. As a result, establishing a circular economy for flexible films will necessitate a substantial expansion in recycling infrastructure that involves better collection, sortation, and end-of-life reprocessing, potentially including widespread use of chemical recycling. The report explains chemical recycling aka advanced recycling is an emerging technology that reverts materials to their original monomers. Its adoption could enhance opportunities for the circular reuse of flexible films by increasing collection, lowering sortation requirements, and improving recycled resin quality by reducing contamination, color, or scent concerns, thereby simplifying the regulatory acceptance of recycled resins for food-contact applications.
Compostable and recyclable packaging in a circular packaging economy.
Compostable packaging has a projected CAGR of 15-16% during the next decade and is receiving a lot of attention because there is a perception that it offers a less-complicated end-of-life option. However, composting also suffers from a lack of infrastructure. According to statistics from the Sustainable Packaging Coalition, only 27% of the U.S. population has access to curbside composting programs, and only 11% of those composting programs accept packaging.
To realize the full circular potential of compostable packaging, the US needs to increase consumer access to composting by investing in the collection of compostable materials and in expanded access to composting facilities that accept food scraps along with packaging. As the US looks at investments into the necessary collection and processing infrastructure, the most immediate impact is likely to be attained if closed systems like stadiums, food service outlets, and cafeterias were implemented before household collection programs.
Recycled-content packaging is a popular path toward circularity. Design for recycling guidelines have been developed by several organizations and are helping the packaging industry choose combinations of polymers, labels, and additives that do not hinder a package’s recyclability. Many brand owners use these guidelines to help meet commitments to increase the use of recycled content. Unfortunately, a disconnect between strong demand and insufficient supply and processing capacity for recycled resin must be overcome. Like flexible packaging, potential solutions lie in simplified and improved collection, better sortation techniques, and greater capacity for end-of-life reprocessing. Chemical recycling could be a potential way to increase capacity as well as recycled resin quality.
Strengthening a circular packaging economy through these seven steps.
Achieving a circular economy depends on improving the infrastructure for collection, sortation, and end-of-life reprocessing. Policy changes will be needed to achieve these objectives. According to the report, establishing a circular economy will depend on the development of…
Extended producer responsibility (EPR). EPR programs shift financial and operational responsibility for end-of-life management of products to producers instead of taxpayers and the government. As of spring 2023, four states (California, Colorado, Maine, and Oregon) have enacted EPR requirements, and more states are considering EPR bills. However, a national law would overcome a patchwork of differing state requirements and simplify compliance. The research within this study indicates EPR programs should include a focus on ways to improve the quality and quantity of recycled materials. Key considerations should explore how best to invest in the composting infrastructure, including packaging, and address how to handle hard-to-recycle materials by investing in collection and sortation technology and supporting end-market development. The data also show package design needs to consider many factors beyond design for recycling. Leveraging EPR to help balance all the design variables should create benefits for each stakeholder.
Universal Access. Providing all households with convenient and consistent access to recycling and composting services would increase collection.
Standardized Definitions. Definitions for commonly used terms like recycling and composting would ensure stakeholders are communicating a consistent message and reduce consumer confusion.
Alternatives to Material Bans. Material bans can prevent CPG companies from choosing the optimum packaging material and increase a product’s environmental impact. Shifting from material bans to dialogues about collection, sorting, and reprocessing gives brand owners the freedom to pick the best option.
Recovery Innovation. Federal investments into programs uncovering emerging science and data are needed to drive efficiencies across packaging design and waste management.
Data Collection. Consistent data collection will help measure and benchmark the performance of a circular packaging economy.
Reusables Infrastructure. Reusables are another promising option to achieve circularity. However, as with other options, infrastructure is lacking, and investment is needed. According to the report, successful reusable packaging programs depend on redesigning distribution systems for reverse logistics. This will involve establishing safe and hygienic drop-off or pick-up collection points, which are convenient to consumers, and equipping production lines for washing and refilling. Currently, the adoption of reusables poses a daunting challenge for many packaging companies due to the costs to develop and scale a system to achieve a significant impact. A collaborative strategy that incentivizes innovation is needed. Understanding the challenges and opportunities of reusables will require participation from a wide range of stakeholders.
A circular economy can be achieved by focusing on how best to invest in recycling and composting infrastructure across the US and tying that dialogue to what is happening with packaging design and the multiple variables packaging designers must juggle. Success will depend on how well members of the packaging value chain understand each other’s challenges and opportunities.
To foster this communication, sustainability will be a major theme at Pack Expo Las Vegas (Sept. 11–13, 2023; Las Vegas Convention Center). A new Sustainability Central area will serve as an interactive resource to learn about design, materials, manufacturing, recovery, logistics, and data. At the accompanying Sustainability Stage, attendees will hear from experts on a range of packaging sustainability topics and learn how to make brands more sustainable. In addition, the Pack Expo Green Program returns to Pack Expo Las Vegas. Pack Expo Green identifies exhibiting companies that provide sustainable solutions via new materials, technology, or strategies such as sustainable processes and machines, renewable and biodegradable packaging, source reduction and lightweighting, recyclable and recycled-content materials, or innovations that reduce carbon footprint
In addition to the focus on sustainability, this year’s PACK EXPO Las Vegas will be the most comprehensive packaging and processing show in North America in 2023.
