Welcome to HBR on Strategy. Case studies and conversations with the world's top business and management experts hand selected to help you unlock new ways of doing business. Most businesses are built on a linear take, make and discard. But that norm is reaching its limits and leaders are under pressure to find smarter, more sustainable ways to operate. Westlyn Ashton is a systems scientist and a professor at the Illinois Institute of Technology. In her masterclass at HBR's 2024 leaders who make a Difference conference, she explains how companies can shift to a circular economic strategy, one that reduces waste, reinvests in communities and creates long term value. She shares how businesses around the world are rethinking products, partnerships and growth itself to build more resilient, regenerative business models. Here's Ashton.

As you look to your future as business leaders, I'd like to reflect on what are the circles and circles cycles in our lives? Right, we have our human life cycle from infant to adults to elders. Our business cycles from product launch to maturity to decline. Our seasonal cycles. So circles and cycles are everywhere in the world around us. It's a very common pattern. But we humans seem to have forgotten that pattern and more recently have begun to follow a more linear pattern of resource extraction, processing and disposal to run our global economy. So I'd like you to think about how can we move back to more circular patterns of resource use and why should we? I believe that we must, and to do so we need to draw on lessons from our past. There's a saying among the Akan people of Ghana that's colloquially known as sankofa, which means that it is permitted to go back and get what you've forgotten. These could be things like traditions that we left behind. As we modernized the ways of caring for each other, for people in place, as we moved from communal living to more individualized modes of success, and also different ways of being enjoying leisure. Nature culture as the way that we measure value and exchange value came to be dominated by money. For the last two centuries, the global economy has operated in a linear fashion of take, make and waste. We take virgin resources to make products that generate lots of waste. Along the way, this economic system has enabled us to improve the material well being of billions of people across the planet. Moving people out of poverty, improving health, increasing well being and lengthening lifespans. But there have been significant environmental and social costs that are not accounted for when we measure business success in terms of profits, growth and market share. As an example, we now have enough clothing on the planet for the next six generations of human. But fashion, fast fashion particularly turns out clothes at such low prices that people rush to purchase them right without thinking about where are these clothes coming from. And increasingly they're using synthetic fibers that are made from fossil fuels, who made them, under what conditions, what were they paid to produce those clothes, and finally, where those clothes end up. So it's estimated that more than 80% of the clothes that we create ends up in landfills, and only 15% is donated or recycled. And of the materials that are donated, a large amount ends up in landfills in the global cell. So there are significant costs of this linear economy that are not borne by businesses, but instead are borne by people and governments. And these externalities have emerged from mindsets that allowed people and nature to be exploited for a minority. From an environmental perspective, our consumption of fossil fuels has led to climate change. Our food and agricultural system takes land from animal habitats, reducing biodiversity. And our industrial activities release pollution that impact us, leading to things like rising cancer rates among humans. Socially, we can think about inequality. And we still see human rights violations within the supply chain. These penalties are disproportionately borne by minoritized and marginalized peoples. Black, brown, rural, poor, small town. As migrants in communities all around the world. But even within that scene of environmental justice and disproportionate harm, we see that there are also stories of resilience, as there's much that we can learn from the resource use practices of our ancestors, Contemporary indigenous peoples as well as people of the global majority whose low levels of disposable income mean that they have grown up learning how to make do with a little sharing. Reusing recycling products many times over. Take Mumbai's Dharavi, one of the world's largest informal settlements. It's estimated that over 15,000 micro enterprises in Dharavi collect, process and recycle more than 80% of Mumbai's waste. And that these recycling enterprises contribute more than $650 million a year to the city's economy. I think we have a massive problem with our economic model and need new, but actually old ways of thinking about how we obtain value and regenerate resources. And I'd argue that we must consider social and environmental justice issues in these new circular economy models. So what is the circular economy? It provides businesses opportunities to create, share and regenerate value from the resources they that they're using. Moving from this current linear extraction and exploitation model to one where we rethink and redesign products and services, share their value with more people through reuse, resale, secondary markets. We extend their durability and reusability and regenerate materials through decomposition or recycling rather than treating them as waste. By shifting to more renewable energy sources, we can curtail our greenhouse gas emissions, Minimize pollution and reduce our environmental footprint. And by restoring and regenerating both natural and human resources, we can sustain the stock of these vital assets that businesses rely upon both in the short and long terms. I think of three ways that we can put the circular economy into action. First, by developing new materials. Second, new business models. Rethinking what and how we sell. And third, new forms of organizational, collaboration and governance. Broadening how we work, who we work with and how. So first, let's take a look at materials. So companies are using their research and development capabilities to develop renewable bio based materials to replace toxic, scarce and expensive ones. Or are developing technologies to convert waste and byproducts to substitute for virgin materials. I'm from the Caribbean. Perhaps many of you have visited the Caribbean. But sargassum is a brown seaweed that floats in mats in the western Atlantic. It provides a habitat for several species of fish. But triggered by climate change and warming ocean temperatures, we now have masses of Sargassum that wash upon the shores of the Caribbean islands and the southeastern United States. This is a huge problem for island and coastal economies that are heavily dependent on tourism. People all across the world flock to enjoy the white sand beaches of the Caribbean. Done. It's estimated that these Sargassum masses cost about nearly $200 million per year in cleanup cost. Right. And that's not including the lost revenues from tourism. So, seeing this problem, several researchers across the Caribbean have been investigating the reuse potential for this biomass. Here I feature Dr. Legina Henry, a lecturer at the University of the West Indies in Barbados, who founded a company called Rum and Sargassum that developed a process to combine sargassum with rum distillery waste, producing a bio based compressed natural gas that can replace gasoline cars for cars on the island. They are currently building a pilot plant to produce and test this biofuel in cars. And it has the potential to replace all of the gasoline imports and carbon emissions associated with them on the island.

For large multinational companies, circularity can appear in many different places. We've just heard from Tarang Amin of elf. Their Project Unicorn was focused on streamlining their product portfolio, placement and presentation. And their packaging was a major component of this strategy because it also represents a huge part of their environmental footprint. In redesigning their products for better store display, they increased the recycled content in the packaging as well as reduced the number of finishes, the number of materials, the number of components in the packaging, which not only reduced cost, but but it also made these products much easier to recycle. Let's switch to thinking about business models such as sharing products and services and finding opportunities in secondary markets in offices all around the world. Perhaps there's a closet in your office. It might not look as messy as this. There are often stockpiles of slightly used but still fully functional equipment and furniture within the same organization. Another department might be looking to purchase similar equipment. Dr. Gary Cooper Jr. Founded Reaply, an asset management platform that got its start helping researchers in universities to find low cost equipment from other labs across campus. Reaply has expanded. It has raised more than $30 million in venture funding. And this funding has enabled it to build a smart inventory management system that organizations can use to manage equipment within their organization to find and sell equipment between different organizations. And Ripley has now expanded their activities to several cities across the United States, so working with cities to develop a marketplace for companies within those cities to share resources. Last year they had over one million items posted on the platform, which generated about two and a half million dollars in savings for customers on that platform. Larger companies might be able to do this themselves. So Hitachi, for example, has developed an AI powered asset management platform that uses analytics and builds a trusted data sharing platform to enable remanufacturing of their products across their own customers. Right. So it's just for their internal use. Finally, there are opportunities for creating new organizational and governance models as the circular economy requires collaboration across supply chains and creating new value networks. Right. This is a big part of the research that I do. It can also create opportunities for reconciliation and repair with groups that have been harmed by exploitative practices. My colleague Erica Allen here in the city of Chicago co founded a nonprofit called the Urban Growers Collective. They are working to build a more just and equitable food system through growing, selling and donating food, as well as educating and training the next generation of black and brown urban farmers. But one of the realities of trying to grow food in urban environments is that our soil is poor and it's often contaminated. But cities also have a tremendous resource in the form of wasted food. We heard earlier that we have this tremendous food waste problem all around the world. In the US we waste close to 40% of the food that's produced for human consumption. So for over a decade, Erika and her colleagues worked together to get funding, permits and devise equitable governance models to launch Chicago's first commercial and for profit anaerobic digester. So at Green Era Sustainability, food waste is converted into heat for growing food in a greenhouse. Methane that's fed to the natural gas grid and compost that sold through a worker owned cooperative. A critical aspect of this organizational model is that the business is partially owned by the nonprofit and community members. We're not only talking about materials being circulated, but wealth in the community is circulated, repairing decades of harm from redlining and disinvestment in the city. So our ancestors, people in low income and low resource communities, have been doing this, making do with what's available and enough. And I'm asking you to think about what can we learn and apply in today's businesses. The circular economy provides many opportunities, but we can't circularize our way to sustainability. Right. We can't recycle everything. And there are significant energy, capital, investment, operational costs that are associated with converting old materials to new ones. In many parts of the world, populations are still growing and people need to grow the infrastructure. So they're going to need more material resources to improve their material well being the well being that many of us in North America, Western Europe and East Asia enjoy. And you know, in many of these places in the more developed the Global north, we are consuming more than we need. So there will be trade offs. For example, you know, we might reduce the carbon footprint of our operations by becoming more efficient, but if we're selling more stuff, then we're negating those savings, right? So we have to think about those trade offs. I think there are also some hard truths that we need to confront about the harms that many of our businesses have caused in certain communities and what we need to do to repair those harms and restore opportunities for wealth building and well being in those places through investment and partnership. So the social entrepreneurs who were featured today were great examples of this type of investment in emerging economies. Economies in the US where we see that there has been underinvestment and there are so many solutions that exist in these places that could grow through investment and through partnerships with investors with businesses that our businesses can also benefit from these opportunities. So you've spent the day listening to all of these great talks and perspectives on leadership. Purpose driven leadership is needed to navigate some of these tensions and make commitments. When the short term ROI for a circularity, a sustainability, a social impact investment might not be as high as other investments, but the social value, the environmental value, the long term value is there. If we could open our aperture to more holistically consider what is important for our businesses, our employees, our customers and our planet, I'd like to ask you to consider how can we transform the understanding of the value that we are creating as well as the value that we're destroying through our actions? How could we instead be regenerating value by reinvesting in partners and places that have been neglected? How can your businesses redesign your products, rethink what you buy, what you sell, reconfigure your operations to eliminate waste and regenerate human and natural resources through your actions. I'd like to end by asking you to think about the fact that we will be ancestors one day and when future generations look back, will they be disappointed or will they be impressed by what we've done? And I ask you, what do you want to be remembered for?

HBR On Strategy: The Promises, Pitfalls, and Trade-offs of the Circular Economy
Episode Overview
In the June 18, 2025 episode of HBR On Strategy, Harvard Business Review delves into the concept of the circular economy with systems scientist and Illinois Institute of Technology Professor Weslyn Ashton. The discussion explores how businesses can transition from traditional linear models of "take, make, dispose" to more sustainable, regenerative practices. Ashton provides insights into the benefits, challenges, and necessary trade-offs inherent in adopting a circular economic strategy, supported by real-world examples and case studies.
Understanding the Circular Economy
Professor Weslyn Ashton opens the conversation by contrasting the conventional linear economic model with the circular economy framework. She emphasizes the ubiquity of cycles in natural and business processes, noting, “Circles and cycles are everywhere in the world around us” (02:17). Ashton argues that humanity has drifted away from these natural patterns towards a linear approach characterized by resource extraction, processing, and disposal. This shift has driven significant economic growth and improved material well-being globally but has also resulted in substantial environmental and social costs that are often unaccounted for.
Quote Highlight:
“As we modernized the ways of caring for each other... the global economy has operated in a linear fashion of take, make and waste.” – Weslyn Ashton (02:17)
The Environmental and Social Costs of a Linear Economy
Ashton details the negative repercussions of the linear model, including climate change, loss of biodiversity, pollution, and social inequalities. She cites the fashion industry as a prime example, where “more than 80% of the clothes that we create ends up in landfills” (05:30). Such practices lead to environmental degradation and place undue burdens on marginalized communities, exacerbating issues like inequality and human rights violations within supply chains.
Resilience Through Traditional Practices
Highlighting resilience, Ashton points to practices from indigenous and low-income communities that inherently align with circular principles. She references Mumbai's Dharavi district, where over 15,000 micro-enterprises manage to recycle more than 80% of the city's waste, contributing significantly to the local economy. This example underscores the potential of circular practices to not only mitigate environmental impact but also drive economic growth.
Implementing the Circular Economy
Ashton outlines three primary strategies for integrating circular economy principles into business operations:
Developing New Materials:
Companies are innovating by creating renewable, bio-based materials or developing technologies to convert waste into substitute materials. Ashton shares the example of Dr. Legina Henry from Barbados, whose company, Rum and Sargassum, combines sargassum seaweed with rum distillery waste to produce bio-based compressed natural gas. This initiative aims to replace gasoline imports and reduce carbon emissions on the island (09:15).
Adopting New Business Models:
Circular business models emphasize sharing, reuse, and resale. Ashton discusses Reaply, an asset management platform founded by Dr. Gary Cooper Jr., which facilitates the sharing and selling of equipment within organizations. With over one million items listed, Reaply has generated approximately $2.5 million in savings for its users (12:19). Additionally, multinational companies like Hitachi are leveraging AI-powered platforms to manage and remanufacture their products internally.
Enhancing Organizational Collaboration and Governance:
Circular economy initiatives often require extensive collaboration across supply chains and the establishment of new governance models. Ashton highlights Urban Growers Collective in Chicago, co-founded by Erica Allen, which transforms food waste into resources like heat for greenhouses and compost. This model not only recirculates materials but also fosters community wealth and repairs historical injustices by involving community members in ownership and decision-making (17:00).
Trade-offs and Challenges
While the circular economy offers numerous advantages, Ashton acknowledges significant challenges. Transitioning to circular models involves considerable energy, capital, and operational costs. Additionally, there are inherent trade-offs; for instance, increasing efficiency to reduce carbon footprints may be offset if it leads to higher product sales and, consequently, greater overall consumption. Ashton states, “We can't circularize our way to sustainability” (19:45), emphasizing that circular practices must be part of a broader, more holistic approach to sustainability.
Addressing Historical Harms and Building Equity
Ashton urges businesses to confront and address the historical harms caused by exploitative practices. She advocates for investments and partnerships that rebuild wealth and opportunities in underinvested communities. This approach not only aligns with circular principles but also promotes social justice and equity.
Quote Highlight:
"We have to think about those trade-offs... what we need to do to repair those harms and restore opportunities for wealth building and well being in those places through investment and partnership." – Weslyn Ashton (20:30)
Leadership for a Sustainable Future
Concluding the episode, Ashton calls for purpose-driven leadership that prioritizes long-term social and environmental value over short-term financial gains. She encourages business leaders to rethink their definitions of success, advocating for strategies that regenerate resources and invest in neglected communities. “What do you want to be remembered for?” she asks, urging leaders to consider their legacy in shaping a sustainable and equitable future (21:00).
Final Thought:
"The circular economy provides many opportunities, but we can't circularize our way to sustainability. We need to transform the understanding of the value that we are creating as well as the value that we're destroying through our actions." – Weslyn Ashton (21:15)
Conclusion
This episode of HBR On Strategy provides a comprehensive exploration of the circular economy, highlighting both its transformative potential and the complexities involved in its implementation. Professor Weslyn Ashton’s insights, supported by diverse case studies, offer a roadmap for businesses aiming to adopt sustainable practices that benefit both the environment and society. As industries worldwide face increasing pressure to operate responsibly, the circular economy emerges as a viable framework for achieving long-term resilience and success.
