An Evolving Industry

Sustainability has become a central focus across many industries, and the world of single-serve coffee is no exception. Compostable coffee pods, in particular, are emerging as a promising way to reduce the environmental impact of daily coffee consumption. Designed to break down naturally and close the loop, these pods offer a tangible opportunity to rethink how the system works.

And yet, despite growing interest, compostable capsules have not yet become the norm in North America. To understand why, it helps to start with the materials themselves.

The Materials Most Commonly Used in Coffee Pods

Over the years, single-serve coffee pods have been made with a range of materials—each with specific technical and environmental characteristics. Understanding their properties is essential for evaluating where the market may be headed.

In the early days of single-serve coffee, many pods were made using a multi-layer structure of polystyrene (PS), EVOH, and polyethylene (PE). This combination was optimized for fast, efficient thermoforming and barrier protection, but posed a serious environmental drawback: it created a multi-material body that couldn’t be separated or recycled through conventional mechanical systems. PS, in particular, lacked established recycling infrastructure in most regions, and its inclusion effectively made the entire capsule destined for landfill.

As environmental pressure mounted and retailers began demanding change, real momentum only began once Keurig Dr Pepper (KDP) formally committed to phasing out PS. That decision triggered a transition across the industry—primarily toward polypropylene-based pods, which were seen as a more recyclable alternative.

Even so, PP-based pods still often end up in landfills due to limitations in infrastructure and user behavior. It was a step forward in some respects, but not a complete solution to the end-of-life challenge.

More recently, new materials have entered the scene—particularly compostable bioplastics such as PLA, PBAT, and PHA, as well as natural fiber-based alternatives. These materials are designed to break down in industrial composting facilities, and in some cases even in home composting systems. They also allow for the organic disposal of the coffee grounds within the pod. However, their success depends on having the right composting infrastructure in place, and on educating consumers about how to dispose of them properly.

The Added Value of Compostable Pods: A New Paradigm

This isn’t a question of right or wrong—it’s part of the natural evolution of the market, particularly in a time when brands are looking for new ways to stand out.

Compostable pods also offer a real opportunity for differentiation, especially in a competitive landscape where products are increasingly similar in quality and price. In this context, sustainability becomes more than just a compliance goal; it becomes a powerful expression of brand values.

Packaging that is designed to compost doesn’t just communicate responsibility—it tells a story that can extend from the materials themselves to the identity and purpose of the brand.

The Companies Already Leading the Way

Some companies have chosen not to wait for the entire system to be ready. Instead, they’ve looked at local opportunities, favorable policies, and growing consumer interest—and made the move toward compostables. Here are a few North American brands that have done just that:

• Club Coffee (Toronto, Canada)
  Developed the PurPod100, one of the first BPI-certified compostable pods. Its success was supported by progressive environmental policies and major retailers like Loblaw.
• San Francisco Bay Coffee (California, USA)
  Operating in a region with strong environmental awareness and access to composting infrastructure, they made sustainability a strategic brand driver.
• Cameron’s Coffee (Minnesota, USA)s
  Leveraged local composting systems in the Minneapolis–St. Paul area to offer certified compostable pods to their loyal Midwest consumer base.
• Mother Parkers (Ontario, Canada)
  Invested in supporting private label brands with compostable solutions, particularly where regional readiness made it a viable option.

These companies show that it’s possible to act now—even if the system isn’t perfect everywhere.

Signs of Market Momentum

Larger players are beginning to move as well. Keurig Dr Pepper, for example, has introduced K-Rounds, a compostable pod format that’s currently in beta testing. It’s a promising sign—not only of technical progress but also of the willingness to engage with municipalities, regulators, and composting stakeholders to help build a more functional system.

This type of leadership could unlock collaboration, clarify standards, and remove barriers that have slowed the sector down for years. It might not solve everything overnight, but it could start tipping the balance.

Europe Is Already Moving: A Source of Inspiration

While North America is in the early stages of exploring and piloting compostable solutions, Europe has been making steady progress for several years. There, the transition is no longer just a future ambition—it’s an established direction.

One standout example comes from Nestlé, which has launched compostable fiber-based capsules compatible with both Nespresso and Dolce Gusto systems. This marks a real shift in the single-serve segment, driven not only by increasingly strict environmental regulations but also by consumer demand that is mature, informed, and engaged.

Italy—home of espresso culture and coffee heritage—has played a leading role in this evolution. It was from Italy that the trend toward compostable capsules as a symbol of innovation and premium quality took off. Iconic Italian brands like Caffè Vergnano and Caffè Borbone have introduced compostable pods for their premium blends, successfully combining great taste with environmental responsibility.

This combination of consumer awareness, regulatory pressure, and a strong drive for innovation is creating the right conditions for acceleration—even in North America, where momentum is clearly building.

Conclusion: The Future Is a Choice

It’s true that not every market is ready in the same way—and that’s perfectly reasonable. Infrastructure, policy, and consumer habits vary from region to region. But that diversity should be seen not as a barrier, but as an opportunity to evolve.

Choosing compostable pods can be more than a technical shift; it can be a strategic brand move—one that signals leadership and creates differentiation.

Because in the end, the real question is: Do we want to follow change—or lead it?

The Need for Real Metrics in Sustainable Packaging

In recent years, sustainability has become a buzzword in the packaging and consumer goods industries. Yet, as businesses race to brand themselves as eco-friendly, the reality is that many sustainability claims lack the backing of standardized metrics. This has given rise to “greenwashing”, where companies overstate or mislead consumers about their environmental impact. To combat this, the industry requires robust tools to measure and verify sustainability efforts in a way that builds trust and drives meaningful change.

One promising solution is the concept of circularity, which emphasizes minimizing waste and maximizing resource efficiency throughout a product’s lifecycle. Circularity challenges us to rethink how materials are extracted, used, and disposed of, moving beyond linear systems to create closed-loop cycles. To make circularity actionable, standardized tools like the Material Circularity Index (MCI) have emerged, offering a measurable way to assess and improve a product’s sustainability performance.

What is the Material Circularity Index (MCI) and Why It Matters?

The MCI is a science-based metric developed by the Ellen MacArthur Foundation to assess how effectively a product or system aligns with the principles of a circular economy. Unlike traditional sustainability measures that focus primarily on carbon emissions or energy consumption, MCI offers a more holistic lens — one that captures how materials are sourced, used, and recovered.

At its core, MCI evaluates factors such as:

• The proportion of recycled or renewable content used in production
• The potential for reuse, recycling, or regeneration at end-of-life
• The degree to which material waste is minimized throughout the product’s lifecycle

This broad, systems-level approach makes MCI especially valuable in industries where packaging plays a critical role, like single-serve coffee. It enables designers, engineers, and brand owners to quantify circularity, not just assume it, and to make informed trade-offs between sustainability, functionality, and cost.

In the context of coffee packaging, for example, MCI can help compare different capsule materials — plastic, aluminum, compostable bioplastics — not just based on how they’re marketed, but on how well they perform in real-world conditions. By integrating MCI into product development, companies gain a powerful tool to optimize for circularity, reduce environmental impact, and align with the growing expectations of both consumers and regulators.

Independent Validation: How WUR Put Coffee Capsule Circularity to the Test

In the search for real metrics to support sustainable packaging decisions, one study stands out for its depth and clarity. Conducted by Wageningen University & Research (WUR) — one of Europe’s leading institutions in agri-food and environmental sciences — this recent research provides a rigorous, side-by-side comparison of single-serve coffee capsules through the lens of circularity.

The findings were illuminating. Flo’s compostable coffee capsules consistently demonstrated higher circularity scores compared to their non-compostable counterparts. This was due to their ability to break down into organic matter that enriches the soil, effectively closing the material loop. In contrast, traditional materials like aluminum and plastic often face challenges such as contamination in recycling streams or limited infrastructure for proper disposal.

These results not only validate the potential of compostable materials but also highlight the importance of metrics like MCI in guiding sustainable design decisions. By providing an objective framework, MCI allows stakeholders to move beyond assumptions and focus on solutions that deliver measurable impact.

Why Compostables Deserve a Second Look — and a First Place in Circular Design

The term “compostable” often evokes skepticism, with critics questioning whether these materials truly live up to their environmental promises. However, when evaluated through the lens of MCI, compostables offer a compelling case for their role in sustainable packaging.

Compostable materials are designed to degrade under specific industrial or home composting conditions, leaving behind no harmful residues. Their circularity scores reflect not only their biodegradability but also their potential to replenish natural systems. For instance, compostable coffee capsules contribute to soil health by returning nutrients to the earth, creating a regenerative cycle.

Moreover, compostable solutions address some of the key shortcomings of traditional recycling systems. While plastics and aluminum require energy-intensive processes to be recycled, compostables bypass these challenges by offering a simpler, more localized end-of-life solution. By integrating compostable materials into packaging design, companies can align with circular economy principles while meeting consumer demand for eco-friendly products.

Using Data to Make Better Decisions

Metrics like MCI are not just theoretical tools; they have practical applications that can transform how businesses approach product development. For companies in the coffee and packaging industries, MCI can serve as a decision-making framework that guides everything from material selection to supply chain optimization.

For example, a brand owner looking to redesign their coffee capsules might use MCI scores to compare the environmental performance of different materials. This data-driven approach ensures that decisions are grounded in measurable outcomes rather than marketing trends or anecdotal evidence. Additionally, MCI can help regulators and sustainability managers set industry benchmarks, fostering greater accountability and transparency.

The implications extend beyond individual products. By adopting MCI as a standard practice, the industry can drive systemic change, encouraging innovation in material science and waste management. The result is a more resilient and sustainable packaging ecosystem that benefits both businesses and the planet.

Conclusion: Moving From Assumptions to Systems Thinking

The journey toward a circular economy requires a shift from isolated efforts to holistic systems thinking. Tools like the Material Circularity Index enable stakeholders to move beyond assumptions and embrace a data-driven approach to sustainability. By providing a clear, measurable framework, MCI empowers businesses, regulators, and consumers to make informed decisions that align with long-term environmental goals.

For the coffee packaging industry, the opportunity is clear. Compostable solutions, validated by studies like those conducted by WUR, offer a pathway to higher circularity scores and reduced environmental impact. However, the responsibility lies not only with manufacturers but also with policymakers and consumers to support and adopt these innovations.

As we look ahead, the integration of circularity principles into packaging design will be instrumental in building a more sustainable future. By prioritizing metrics like MCI, the industry can move from rhetoric to action, creating products that are not just convenient but also truly sustainable.

The irony of starting a blog in the era of 30-second reels

In a world of hyper-visual, bite-sized communication—where stories disappear in 24 hours and attention spans flicker between TikToks and Reels—you might wonder: why launch a blog in 2025?

Fair question. And here’s our honest answer: because some conversations deserve more than 15 seconds.

At KeyGea, we believe the topics we care about—packaging sustainability, material innovation, environmental impact—are too complex, too nuanced, and frankly, too important to be reduced to a slogan or a swipe. So, while we’ll still show up in the fast lanes of digital media, we’ve decided to take a slower road. A more reflective one. One where we can explain, explore, and sometimes even question ourselves.That’s why this space exists. Once a month, we’ll share what’s on our mind—from scientific insights to market shifts, project learnings to philosophical contradictions. Not to sell you something. But to start a conversation that’s worth having.

Why we felt the need for this space

At Flo Group, we’ve spent over a decade developing KeyGea—a fully compostable pod for single-serve coffee. It wasn’t just a technical journey, but a values-driven one. Along the way, we met engineers, scientists, roasters, retailers, and activists. And what we discovered is this: everyone has something to say about sustainability, but not everyone has a space to say it well.

Blogs may seem “retro,” but we see them differently. They’re one of the few formats left that allow for depth without distraction. A place where we can share what we’ve learned and hear back from a community that’s just as passionate about doing things better.

More than ever, we need real dialogue—between industries, across supply chains, and especially between producers and consumers. Because packaging is no longer just a technical choice. It’s a moral one, a business one, and increasingly, a cultural one.

The problem with how we talk about sustainability

Let’s be honest: “sustainability” has become a buzzword.

It’s on every label, every investor deck, every press release. But when everything is sustainable, nothing really is. The danger of overuse is dilution—and that’s exactly what we want to push back against.

We want to bring clarity back to the conversation. We want to look at lifecycle data, dive into certification schemes, question assumptions, and examine tradeoffs—not to win an argument, but to improve a system. Because sustainability isn’t a label. It’s a process. A messy, sometimes contradictory process that requires critical thinking and collaboration.

That’s what this blog aims to offer: a space to talk about what sustainability actually looks like—on the factory floor, in procurement meetings, in consumer feedback loops, and in our own internal debates.

What to expect from us

You can expect one post per month. Nothing spammy, nothing superficial.

Sometimes we’ll write about the technical side of compostable materials. Sometimes we’ll unpack consumer trends or regulatory shifts. Other times, we’ll share behind-the-scenes reflections from our R&D team or stories from our partners in the field. But always with the same goal: to invite you in—not just to what we do, but why we do it.

We promise transparency over polish, insight over perfection, and questions over certainties. Because that’s what we believe this space needs more of.

Let’s co-create the future of sustainable packaging

This blog isn’t just about KeyGea. It’s about a broader ambition: to bring together people who care—whether you’re a roaster testing compostable lines, a co-packer navigating new machinery, a sustainability officer trying to interpret policy, or a consumer who just wants to know if their morning brew makes a difference.

We believe change doesn’t happen in isolation. It happens in dialogue. It happens when people with different roles but shared intentions come together and ask, what could we do differently?

So here’s our ask: stick around. Read, reflect, reply. Tell us what you’d like us to write about. Disagree with us when it makes sense. Help us make this blog a real meeting point for ideas.And if you want to stay in the loop, consider subscribing to our monthly Field Notes—a short, curated email with each new post and a few extras we only share with our close circle. No fluff, no noise, just thoughtful content
