Across all consumer goods categories, the U.S. is striving to limit packaging waste and to slow the flow of landfill contributions. Regulators and environmentalists know that time is running out to combat climate change and that moving from a linear to circular model is one of the most effective strategies for preserving materials, reducing resource consumption and decreasing production-related emissions. Yet recycling rates in the U.S. continue to fall short of their potential — largely due to a lack of access and understanding for consumers. This raises the question: If we could simply improve consumer recycling habits of consumers for even one type of packaging, how much could we shift future recycling rates and landfill volumes?

Aluminum as a clear avenue

The beverage can serves as a package with unique opportunity for moving the needle, given its market-ready path toward a greater circular economy. While most modern consumers know that the beverage can is a recyclable item, many do not understand just how impactful that recyclability is in terms of the bigger picture. Used beverage cans are able to be recycled from an empty can to a new can on the shelf in as few as 60 days — a remarkable turnaround that not only saves precious materials from landfill but also saves more than 90% of the energy required in production using virgin materials.

Aluminum cans are also one of the highest-valued formats in the recycling stream given the fact that they can be recycled an infinite number of times without loss of properties like strength and durability. In fact, the Can Manufacturers Institute says that the profit from aluminum beverage cans effectively enables the entire recycling system to operate — typically accounting for more than 33% of the revenue at an average MRF, more than any other single material commodity.

Unfortunately, the majority of consumers are unaware of the importance of UBCs for recycling systems and are not always committed to making responsible choices for material disposal, leaving a tremendous opportunity gap for greater collection.

Creating care and commitment within consumers

While there are numerous ways to make beverage can recycling easier for consumers, there is no action without buy-in. Consumers must feel connected to the products they are using as well as
personally responsible for their choices in order to develop new, more productive habits.

With this in mind, driving consumer education about the damaging effects of landfill waste and resource consumption on the future of our planet, as well as the benefits of properly disposing of key packaging formats like the beverage can, helps to drive more mindful behavior and long-term stewardship.
When a consumer knows that the way they interact with just one beverage can plays a tangible role in a potential environmental outcome, they are more apt to do their part.

Often this education can be done in tandem with localized events where can collection is active and accessible. Some examples include:

• Sponsoring contests at sporting events: Various minor league teams around the U.S. have received sponsorship support from manufacturers and beverage brands to hold a collection contest of all used beverage packaging in stadium and arena stands, incentivizing responsible disposal and recycling on-site while providing longer-term education and reminders to all attendees along the way.
• Hosting competitions at schools: CMI has led a One Million Can Challenge with elementary schools in key regions of the U.S. to drive awareness of the importance of UBC collection not only with families and communities but with the younger generation, who can develop impactful habits early on.
• Creating greater accessibility in high-consumption areas: Metal packaging industry initiatives like Every Can Counts continue to meet consumers where they are, placing recycling ambassadors at local festivals, community parks, academic institutions and other high-traffic areas where passersby can be taught to be more thoughtful about recycling in relation to their daily activities and lifestyles.

Strength in numbers

Ultimately, when it comes to increasing national recycling rates, it is imperative we remember that small actions can create significant impact. Focusing on one substrate, and partnering with one school or one neighborhood to drive more awareness, can be part of a much larger patchwork of efforts happening across the U.S. With the mindset that no one initiative is too minor, we stand a chance to advance the circular economy and foster a much healthier environment long-term.

Designing packaging for recyclability is an important part of building a circular economy. For plastics, structures that are designed with consideration for existing recycling methods can contribute to higher-
quality recyclate and help strengthen the supply of post-consumer recycled material in the future. Although it involves a thorough understanding of downstream collection and recycling processes, designing for recyclability really begins with upstream producers.

Beyond performance and aesthetics, examining packaging from a recycler’s point of view involves considering how the package could be collected, sorted and processed. Because mechanical recycling is the most widely available recycling method today, many companies are moving toward mono-material packaging designs that could enable higher-yield PCR feedstock bales in the future. However, mono-material structures must be able to meet the necessary barrier and sealing requirements of incumbent structures to be a viable alternative to mixed-material laminates and films. Balancing these performance requirements, equipment capabilities and consumer expectations of how the package should function can prove quite difficult for brand owners.

How can the packaging industry advance technology innovations that fulfill all of these specifications? Through their studies exploring how to build a circular economy, the Ellen MacArthur Foundation has identified external input and breaking down silos as two key ingredients for a successful upstream innovation process. Brand owners know the type of product and experience they want to deliver to consumers. Suppliers understand the capabilities and limitations of different materials. Bringing various areas of expertise together through cross-value-chain collaboration streamlines and accelerates the commercialization of packaging solutions that deliver the desired experience for consumers while considering the post-use cycle of the product.

The growing availability of high-density biaxially oriented polyethylene is one example that illustrates how resin suppliers, film manufacturers and original equipment manufacturers worked together to bring a new PE material to market that enables new types of mono-material packaging. Working with biaxial film manufacturers like Inteplast, Nova Chemicals expanded BOPE-HD availability and capacity by running trials and collaborating closely with the experts in biaxial film production. These relationships helped refine the BOPE-HD formulation to meet converter and brand owner requirements. “Every step of the value chain has to work together in order to make sure that we end up with a product that meets the needs of the market,” said Latricia Fry, market and business development manager at Inteplast.

Market demands

The development of BOPE-HD began with an increased interest in mono-material PE solutions from brand owners. Motivated by NGOs like the Ellen MacArthur Foundation, emerging extended producer responsibility legislation and consumer preferences, many companies have made sustainability commitments related to making packaging recyclable and incorporating PCR materials.

PE is suitable for a wide variety of packaging applications due to its moisture barrier properties. While HDPE has established recycling streams and is one of the most recycled types of plastics, the majority of flexible packaging films end up as waste. Store drop-off programs are currently the only consumer recycling program for plastic films on a large scale, and they only accept a portion of PE flexible packaging. GreenBlue, the organization behind the How2Recycle labeling system, reports that only 36% of program members’ flexible packaging qualifies for store drop-off recycling, while the remaining 64% is not yet accepted.

In light of its versatility and its developing options for recycling, PE is a common choice for mono-material packaging designs. When Inteplast began exploring BOPE, they started with linear low-density
PE but discovered that it could not meet all of their customers’ needs. The goal of designing mono-material structures is to replace multi-material PET and PE laminates. These materials demonstrate high stiffness and heat resistance, and LLDPE could not meet the same types of processing requirements. The market was demanding an HDPE solution.

Product development

Nova Chemicals started down a new path altogether when they began developing their BOPE-HD resin for tenter frame lines, as the process requires a different formula than blown PE film. To create the resin that could run on commercial tenter frame lines, including lines designed for biaxially oriented polypropylene, they had to create a completely new formula that would not slow down or limit production. As all operators work on maximizing line speed, maintaining productivity for the new HDPE material was essential, though working with HDPE in this process is technically challenging. To develop a functional resin that could be widely adopted, Nova formed strategic relationships with film manufacturers.

Nova and Inteplast embarked on a journey to test resin formulations and production processes for the BOPE-HD resin. The Nova team conducted trials on Inteplast’s tenter frame lines. Nova and Inteplast team members attended OEM demonstrations together to better understand how the resins could run on existing and new equipment. At Nova’s Centre for Performance Applications in Calgary, Inteplast and other brand owners tested films on converting equipment and shared feedback to improve the functionality of the resin.

Benefits of collaboration

Developing a new product requires lots of testing and many different iterations. The exchange of information and an open dialogue between multiple industry players throughout the process aligns everyone’s objectives, helping teams pursue the right research and modifications. “Any time a packaging design changes, there will never be a drop-in solution that solves everyone’s problems,” Fry explained. “Adjustments will always need to be made, and sharing feedback during the development stage ensures that we are all following the right path and narrowing in on our process.”

For mono-material structures, new films need to work within existing production capabilities to be competitive and profitable. Collaboration enables new developments that account for the manufacturing, processing and performance needs throughout the entire packaging value chain. “Collaboration really is the only way we’re going to be able to solve the demand for circularity when it comes to flexible films,” said Fry.

The industry must focus on creating accessible mono-material packaging solutions that provide an alternative to non-recyclable, mixed-material films. As the world comes together to increase plastic recycling and reduce plastic waste, it is important to start these system-level changes with existing opportunities like packaging designed for store drop-off programs and optimized for mechanical recycling processes. Downstream solutions alone will not be able to tackle plastic without upstream innovation supported by diverse teams and collaborative thinking.
