Circular Economy Leaders: How US Companies Are Eliminating Waste and Building Sustainable Supply Chains

The linear economy—take, make, waste—is increasingly recognized as both environmentally destructive and economically inefficient. A circular economy model, by contrast, designs waste out of the system by keeping materials in use for as long as possible and regenerating natural systems. While Europe has led circular economy policy development, a growing number of American companies are pioneering circular business models that demonstrate sustainable profitability, supply chain resilience, and competitive advantage.

What Is the Circular Economy?

The circular economy is an economic model designed to eliminate waste and the continual use of resources. It is based on three principles: designing out waste and pollution, keeping products and materials in use, and regenerating natural systems. This contrasts with the traditional linear model in which raw materials are extracted, manufactured into products, used, and discarded.

The Ellen MacArthur Foundation, the leading global advocate for circular economy transition, estimates that applying circular economy principles to five key areas (cement, aluminum, steel, plastics, and food) could reduce global CO2 emissions by 9.3 billion tonnes per year by 2050—roughly equivalent to eliminating all current transportation emissions. The economic opportunity is equally significant: the Foundation estimates that circular economy principles could generate $4.5 trillion in additional economic output by 2030.

Apple: Closing the Materials Loop

Apple has made circular economy principles central to its environmental strategy, with ambitious commitments to use only recycled or renewable materials in its products and to achieve carbon neutrality across its entire value chain by 2030. The company’s Daisy robot can disassemble 1.2 million iPhones per year, recovering rare earth elements, gold, cobalt, and other valuable materials that would otherwise be lost in mixed electronics recycling streams.

Apple’s Material Recovery Lab in Austin, Texas develops new processes for recovering materials from consumer electronics at industrial scale. The company has achieved 100% recycled cobalt in all Apple-designed batteries, 100% recycled tin in the main logic board solder of many products, and uses recycled aluminum in the Mac Pro enclosure. Its packaging is 99% fiber-based and fiber sourced from responsibly managed forests.

Apple’s iPhone Trade In program collected 12.2 million devices for reuse or responsible recycling in fiscal year 2022. By extending product life through refurbishment and trade-in programs, Apple keeps materials in the economy longer while capturing value that would otherwise be lost to landfill or low-grade recycling.

Interface: Carpet Tiles and Carbon Mission Zero

Interface, the Atlanta-based modular flooring manufacturer, pioneered circular economy principles in manufacturing decades before the term became mainstream. Founder Ray Anderson’s epiphany about his company’s environmental impact in 1994 launched Mission Zero, a commitment to eliminate negative environmental impact by 2020—a goal the company substantially achieved.

Interface’s ReEntry program takes back used carpet tiles for recycling and reuse. The company’s carpet tiles are designed for disassembly, with face fiber and backing separable for different recycling streams. Interface uses recycled nylon (including fishing nets recovered from oceans through its Net-Works partnership with communities in the Philippines and Cameroon) and recycled backing materials in its products, and designs products for eventual recovery and reuse.

Interface’s Climate Take Back mission goes further, committing to run its business in a way that is restorative to the planet. The company has developed carbon-negative product lines, worked to sequester carbon in its products and manufacturing processes, and is pursuing the vision of becoming a carbon sink—absorbing more carbon than it emits across its full value chain.

Patagonia: Repair, Reuse, and Responsible Materials

Patagonia has built its brand around circular economy principles and radical transparency about environmental impact. The company’s Worn Wear program encourages customers to buy used Patagonia gear, repair items they own, and return end-of-life products for responsible recycling. Patagonia employs a team of repair technicians and has partnered with iFixit to provide repair guides, extending product lifetimes significantly compared to fast fashion alternatives.

Patagonia’s product materials strategy prioritizes recycled content. The company uses recycled polyester (made from plastic bottles and used garments), recycled nylon, and organic cotton. Its ReCrafted collection creates new products from worn-out gear that can no longer be repaired, giving material new life rather than downcycling or discarding it.

Patagonia’s conversion to a trust structure—in which all voting stock is held by the Patagonia Purpose Trust and all non-voting stock donated to the Holdfast Collective, an environmental nonprofit—ensures that profits are perpetually directed toward fighting climate change and defending democracy, embedding circular and sustainability principles at the ownership level.

Caterpillar: Remanufacturing at Industrial Scale

Caterpillar’s remanufacturing division (Cat Reman) is one of the world’s largest industrial remanufacturing operations, restoring used components—engines, transmissions, hydraulic units, fuel systems—to original performance specifications using a fraction of the raw materials and energy required to manufacture new parts. Cat Reman processes more than 2 million core returns annually across facilities in the US, Europe, and Brazil.

The economics of remanufacturing are compelling: remanufactured components typically cost 40-70% less than new equivalents while meeting the same performance specifications. This creates value for customers while substantially reducing resource consumption—Cat Reman estimates that its operations save approximately 1.5 million tons of raw material and 79.2 million gallons of oil annually compared to manufacturing equivalent new components.

Caterpillar’s approach demonstrates that circular economy principles can be economically competitive at industrial scale, not just in consumer goods or high-value electronics. The remanufacturing model creates a recurring revenue stream, strengthens customer relationships through the core return program, and reduces exposure to commodity price volatility.

Walmart: Closing the Loop on Packaging

As the world’s largest retailer, Walmart’s commitment to circular packaging could have transformative impact on consumer goods packaging throughout the US economy. Walmart’s Project Gigaton targets reducing one billion metric tons of greenhouse gas emissions from its supply chain by 2030, with packaging circularity as a key lever. The company’s sustainable packaging commitments include goals for 100% recyclable, reusable, or compostable private brand packaging by 2025 and for incorporating post-consumer recycled content in packaging.

Walmart has invested in TerraCycle’s Loop initiative, which delivers consumer products in reusable containers that are collected, cleaned, and refilled rather than discarded after single use. While Loop has faced scaling challenges, it represents Walmart’s commitment to testing circular business models for fast-moving consumer goods.

The Circular Economy Investment Landscape

For investors, the circular economy presents both opportunities and risks. Companies successfully transitioning to circular models often enjoy supply chain resilience through reduced raw material dependence, cost advantages from materials efficiency, and access to the growing segment of consumers and corporate buyers prioritizing sustainability credentials.

Dedicated circular economy investment funds are emerging. Circularity Capital in Europe focuses specifically on circular economy companies. Among thematic ETFs, the iShares MSCI Global Sustainable Development Goals ETF (SDG) and the Parnassus Core Equity Fund both incorporate circular economy criteria alongside broader sustainability screens.

Venture capital is flowing into circular economy innovation across materials (biodegradable packaging, recyclable thermosets), business models (product-as-a-service, peer-to-peer sharing platforms), and infrastructure (advanced recycling technology, material traceability platforms). Companies like Rubicon Technologies (waste management optimization), Renewlogy (plastic-to-fuel conversion), and PureCycle Technologies (polypropylene recycling) are commercializing circular economy technologies at scale.

Challenges and the Path Forward

Scaling circular economy principles faces real obstacles. Linear business models are often entrenched in tax structures, accounting conventions, and procurement habits that undervalue durability and repairability. Recycling infrastructure in the US remains inadequate, with significant gaps in food waste composting, textile recycling, and materials collection in rural areas. Consumer behavior change requires sustained engagement, and the “right to repair” movement is still fighting against manufacturers who design products to be irreparable.

Policy is beginning to shift. Extended producer responsibility (EPR) legislation—which makes manufacturers responsible for the end-of-life management of their products—is gaining traction in US states including California, Oregon, Colorado, and Maine. The EU’s Ecodesign for Sustainable Products Regulation is setting design requirements for circularity that will affect US companies selling into European markets. These policy signals are creating clearer business cases for circular design investment.

The companies profiled here demonstrate that circular economy principles are not merely idealistic—they generate competitive advantage, build brand loyalty, reduce supply chain vulnerability, and create pathways to profitability that are more resilient in a world of resource constraints and climate disruption. The transition from linear to circular is not optional for companies serious about long-term sustainability; it is the strategic imperative of the coming decade.
