A tale of two snack pouches
Spoon-fed applesauce has become something of a relic of the past in little over a decade, replaced by on-the-go fruit pouches that toddlers can squeeze in one hand and slurp. The pouches are easy to stash in a purse, last for months in a pantry and are relatively nutritious.
But while parents appreciate the convenience of these minimal-mess snacks, many also cringe when they toss the single-use packaging into the trash. Most of these pouches are made of layered films and other plastic materials that are difficult, if not impossible, for U.S. municipal recycling systems to peel apart and process. So, to the landfill they go.
Demand for flexible food packaging is set to become a $3.4 billion market by 2022, a growth of nearly 4 percent per year, according to a Freedonia Group report several years ago. That includes an array of pouch designs beyond the juvenile market, such as stand-up zippered bags for things like popcorn and cookies. Food companies increasingly favor the bendable, smashable packaging for being lightweight and therefore low-carbon when it comes to shipping, so it's in their best interest to improve the sustainability of the materials while winning over the vocal segment of ecologically-aware, social media-savvy millennial moms and dads. And sales of baby-food pouches appeared to flatten or dip slightly in the past couple of years, according to market research by Spins and IRI.
That's partly why two leaders in the world of pureed-fruit pouches have invested years toward reinventing their packaging, some of which is set to reach the market as soon as this spring. GoGo Squeez maker MOM Group and Nestlé's Gerber have each taken a different tack, ultimately picking different polyolefins for their primary material: polyethylene for GoGoSqueez and polypropylene for Gerber.
At this point, however, neither of the new pouches will be accepted by most mainstream recyclers in the United States, which mostly focus on paper and corrugate and lack the materials sorting-and-stripping capabilities to handle flexible plastics. The companies appear to be banking on the potential that recycling innovations that are widespread in Europe will eventually reach U.S. shores, yet this is largely beyond their reach. (Nestlé is making separate investments in this direction; more on that below.)
Here's what's inside the pouch-reinvention efforts by each company.
specializes in low-footprint, circular solutions for packaging, which span a range of processes including extrusion, lamination, printing, pouch making and injection molding. It has nine production plants in seven countries and nearly 2,000 people on its payroll.
"That’s when it got more real, from exploratory investigations to doing more trials. That’s when we found the path," Dzikowicz says. "From there it’s been a series of evolutions. Multiple iterations ultimately got us to the first monomaterial pouch."
In 2018, the team settled with Gualapack on what it calls the industry's first single-material pouch. The pouch and cap are both 100-percent polypropylene, which was chosen for its recyclability in Europe. The results are open source, so other companies can use the technology if they like.
"We had to design our pouch to be intrinsically recyclable, meaning anywhere you go you can remelt and extrude it and make something out of it," said Michelle Marrone, Gualapack's product innovation and sustainability project manager.
In Europe, recycling facilities commonly feature optical infrared high-speed scanners that can "read" incoming garbage and sort out even flexible materials, such as the snack pouches. European Union policy on the circular economy includes a goal for all plastic on the market to be reusable or recyclable by 2030.
In the United States, by contrast, the technology has not been widely invested in and installed. "If [the packaging] is not properly separated and sent to a recycler there’s really no control we have over that," Marrone said.
Gerber will start in May by selling its new pouch, containing organic banana mango puree, on its website. Then it'll take time to scale up to its portfolio of 80 different types of pouch snacks. Anything that contains dairy, which is more challenging to keep fresh than fruit alone, will require a different approach.
"This is a step in the process," Dzikowicz said. "There are many things that come together. It’s not only with us, what we as a manufacturer can provide, but the entire system needs to work."
Enter Nestlé's broader packaging mission, which includes supporting local recycling infrastructure. Nestlé joined Materials Recovery for the Future (MRFF) several years ago as a founding member alongside Dow Chemical, PepsiCo, SC Johnson and several other big corporations. The research program from the American Chemistry Council is piloting curbside recycling for flexible plastic packaging.
Under the experimental project, Pottstown, Pennsylvania, has become the first U.S. community to collect and recycle thin-film plastic. Gerber says that both its current and future fruit pouches can be recycled with the technology at play there, which involves sophisticated optical sorting systems. Material from the pouches can be turned into plastic pellets or industrial materials such as composite lumber or roofing.
The ultimate goal of the MRFF project is to accelerate such advancements nationwide. Still, there's a long road ahead before popular flexible packaging can be diverted at scale from the junkyard. Its use keeps on rising, particularly as companies favor the lightweight packaging for reducing energy use and carbon emissions at shipping time.
Representatives on the recycling and materials recovery side tend to curse product designers for failing to consider what happens after their creative packaging is spent. Wanda Redic, senior recycling specialist for the City of Oakland, California, is among those critics who describe the widespread practice of "wish cycling" by consumers who unwittingly contaminate household recycling bins with items they assume to be recyclable.
A product is not recyclable if no one can recycle it, she said, warning of "putting the cart in front of the horse. They're making a better container that one day will be recycled. In the meantime, it’s going to the landfill."
The people behind GoGo Squeez and Gerber's pouches say they hope they're doing their part to advance better packaging solutions, while recognizing that the patchwork U.S. recycling system leaves much to be desired. One hope is that down the road, if more flexible polypropylene and polyethylene are available for recycling in these new types of formats, they would be collected at greater volumes. And if more plastics enter the market for upcycling purposes, that might spur investment in recycling infrastructure. It's a kind of chicken-versus-egg situation. In this case, the designs may come first.
"We're doing the piece we can do, we’re supporting the MRFF project, but we really need the system to come together," Dzikowicz said.
