| 10/15/26 | Peter Singer on Profit for Good: Can Business Make More Money by Giving It Away? | What if giving away your profits actually made your business stronger? In this milestone 200th episode of Business For Good, host Paul Shapiro sits down with Peter Singer, widely regarded as the world's most influential living philosopher, to explore why companies should commit at least 10% of their profits to effective charitable causes and how doing so might attract customers, motivate employees, and ultimately grow the business. Peter co-founded the Profit for Good initiative with Julia van Boven, and in this conversation he lays out the case for a new standard in how businesses treat their profits. He explains why he believes it is possible to become a billionaire ethically, why capitalism remains the only system that has lifted hundreds of millions out of poverty at scale, and why the question is not whether to earn wealth but what you do with it once you have it. The conversation also turns to Peter's assessment of the animal protection movement fifty years after he published Animal Liberation. He explains why his call for a boycott of meat has been, in his own words, a dismal failure, why people are far more conservative in their eating habits than he anticipated, and why technological invention rather than moral persuasion may ultimately do more to reduce animal suffering. Things You Will Learn: Why Peter Singer argues that giving away profits could attract customers, recruit better talent, and grow a business. Why Peter believes it is ethical to be a billionaire, provided you are actively planning how to use that wealth for good. Why the animal protection movement has failed to reduce the total number of animals raised for food despite fifty years of advocacy. How technological alternatives to animal products may do more to reduce suffering than moral persuasion alone. Why Peter supports family planning as an effective intervention for reducing both poverty and environmental harm. Tools & Frameworks Covered: Profit for Good Model: A framework in which companies commit at least 10% of their profits to effective charitable causes, with the thesis that this commitment can also serve as a competitive advantage by attracting purpose-driven customers and employees. Progressive Giving Scale: Peter's graduated donation framework from The Life You Can Save, where individuals start at 1% of income and increase the percentage as their earnings grow, reaching 10% or more at higher income levels. Charity Ownership Advantage: A model being developed with Brad West in which philanthropists acquire existing for-profit businesses and convert them into profit-for-good entities, redirecting 100% of profits to charity while preserving existing management and operations. #BusinessForGood #SustainableBusiness #FutureOfFood #AlternativeProtein #PeterSinger #ProfitForGood #EffectiveAltruism #AnimalLiberation #EthicsOfWealth #CharitableGiving #FactoryFarming #AnimalWelfare #EffectiveCharity | 1h 08m 30s | ||||||
| 10/1/26 | Forty Years of Farm Sanctuary: Gene Baur on What's Worked and What Hasn't | In 1986, Gene Baur co-founded Farm Sanctuary with a simple theory: show people how factory farming works, and they will stop eating animals. Forty years later, per capita meat consumption in America has risen from 196 pounds to 232 pounds per person, and the number of farmed animals entering U.S. slaughterhouses has doubled from roughly 5 billion to 10 billion. In this episode of Business For Good, Paul Shapiro sits down with his longtime colleague and friend to ask the hard question: what actually moves the needle for farmed animals? Gene traces the arc from early investigations and rescues through the wave of statewide ballot initiatives banning battery cages, gestation crates, and veal crates, and explains why he now believes systemic and institutional change matters more than individual persuasion. The conversation covers why awareness campaigns alone have not reduced meat demand, how institutional reforms like default-veg programs and livestock taxes could reshape consumption patterns, and why Gene believes farm sanctuaries can evolve into self-sustaining hospitality operations that model an alternative food system. Things You Will Learn: Why 40 years of awareness campaigns have not reduced meat consumption, and what Gene Baur thinks will actually work. How institutional reforms like default-veg programs and livestock taxes could reduce meat demand without relying on individual persuasion. Why Gene believes farm sanctuaries can become self-sustaining hospitality operations that model an alternative food system. How historical patterns of technological displacement, from whale oil to horse transport, may predict the future of animal agriculture. Why Gene thinks the vegan movement's perfectionism has undermined its own goals. Tools & Frameworks Covered: Red Campaigns vs. Green Campaigns: A framework for understanding two types of advocacy. Red campaigns mobilize people through opposition to cruelty, like banning gestation crates. Green campaigns motivate through positive experiences, like community gardens, plant-based hospitality, and personal wellness. Institutional Choice Architecture: Changing default options in hospitals, schools, and public programs so that plant-based meals are the first option presented, reducing meat consumption without requiring individual behavior change. Sanctuary-as-Hospitality Model: Reimagining farm sanctuaries as revenue-generating operations that combine animal care, plant-based food production, visitor experiences, and education, enabling replication without depending solely on philanthropy. #BusinessForGood #FutureOfFood #AlternativeProtein #SustainableBusiness | 49m 14s | ||||||
| 9/15/26 | Inside the Alt Protein Job Market with Noga Golan | Is alternative protein really a failing industry, or are investors just applying the wrong timeline? Noga Golan, Founder of Food Impact Partners and Food Impact Careers, has an unusually clear view of that question. Her executive recruiting firm and free job board sit at the intersection of candidate demand and company hiring across the global food innovation landscape. In this episode with Paul Shapiro, Noga shares data from nearly 60,000 job views and 35,000 application clicks in the first half of 2026, revealing that companies are still actively hiring even as the broader narrative around alternative protein remains pessimistic. Commercial roles now account for 34 percent of job postings, a signal that the sector is shifting from R&D toward revenue generation. Candidates remain especially drawn to fermentation and cultivated meat positions, often with more enthusiasm than skepticism about the sector's future. Noga argues that much of the perceived distress stems from applying venture capital and software timelines to an industry that still has to build physical supply chains, achieve price parity, and shift consumer behavior. She compares the current moment to the dot-com correction, suggesting that the boom-and-bust cycle may look like noise over a 20- to 30-year horizon. Things You Will Learn: Why alternative protein may be suffering from a timing mismatch rather than a technology problem. How the shift toward commercial hiring signals that food tech companies are moving from invention to revenue. Why candidate interest remains strongest in fermentation and cultivated meat despite sector headwinds. Why mission-aligned employees are not automatically more productive than those motivated by other factors. How founders can avoid common hiring mistakes by focusing on execution goals rather than idealized candidate profiles. Tools & Frameworks Covered: Product Market Fit as a Hiring Lens: Evaluating startup viability and team-building decisions through obsessive focus on the end buyer, rather than leading with technology or mission as the primary filter. Goal-Based Executive Search: Structuring the recruiting process around a company's 12- to 18-month business objectives and anticipated challenges, rather than matching resumes to static job descriptions. Sector Timing vs. Technology Readiness: Distinguishing between an industry that has failed and one where investor expectations were calibrated to software-speed returns in a physical production business. #BusinessForGood #AlternativeProtein #FutureOfFood #FoodTech #FoodInnovation | 45m 26s | ||||||
| 9/1/26 | How Two Grad Students Teamed Up With Sam Altman to Build an $8 Billion Nuclear Energy Company | How does a nuclear energy startup with roughly a million dollars in revenue become an $8 billion publicly traded company sitting on $3 billion in cash? In this episode of Business For Good, Paul Shapiro sits down with Caroline DeWitte, Co-founder and COO of Oklo, to find out what investors are betting on and why the company believes it can deliver. Oklo is building compact nuclear powerhouses that use fast neutrons to extract up to 95 percent of the energy in nuclear fuel, compared to roughly five percent in conventional reactors. The company plans to run its first plants on recycled fuel from a reactor that operated from the 1960s through the 1990s, turning what most people consider nuclear waste into a viable energy source. DeWitte explains how the system shuts itself down through natural physics if something goes wrong, eliminating the need for the layers of backup systems that drive up costs in traditional nuclear plants. The conversation traces Oklo's evolution from a one-megawatt micro-reactor concept to 75-megawatt powerhouses designed for data centers and utilities. DeWitte discusses how Sam Altman became an early backer and longtime board chair, why the company chose to go public through a SPAC during what she calls the doldrums after the SPAC rush, and how President Trump's reactor pilot program allowed Oklo to begin construction under an accelerated Department of Energy pathway. Things You Will Learn: How fast reactors can recover up to 95 percent of the energy in nuclear fuel, compared to roughly five percent in conventional water-cooled reactors. Why Oklo's reactor design shuts itself down through natural physics without any human intervention. How the company went from a grad school idea to an $8 billion publicly traded company backed by Sam Altman. Why President Trump's reactor pilot program dramatically accelerated Oklo's construction timeline. How Oklo brought a reactor from a greenfield site to nuclear criticality in under a year. Tools & Frameworks Covered: Fast Reactor Technology: A nuclear reactor design using fast neutrons and liquid sodium cooling that can fission elements conventional reactors cannot, enabling fuel recycling and dramatically higher energy extraction from uranium. Nuclear Fuel Recycling: A process for reprocessing spent nuclear fuel so that up to 95 percent of its energy content can be used, reducing the volume and half-life of remaining waste from thousands of years to a few hundred. Reactor Pilot Program (DOE Pathway): A federal framework allowing the Department of Energy to work with the NRC on reactor reviews and permit early construction, significantly compressing deployment timelines for advanced nuclear companies. #NuclearEnergy #AdvancedNuclear #CleanEnergy #NuclearInnovation #EnergyInfrastructure #Oklo #BusinessForGood | 47m 56s | ||||||
| 8/15/26 | The Geothermal Startup That Made It Big | What if the same drilling technology that powered the shale boom could be redirected to produce clean, carbon-free electricity around the clock? In this episode of Business For Good, Paul Shapiro sits down with Tim Latimer, CEO and chairman of Fervo Energy, to explore how a former oil and gas drilling engineer built one of the most celebrated clean energy companies in the country in under a decade. Tim started Fervo in 2017 with two core beliefs: that the world would need more reliable clean electricity, and that advances in horizontal drilling had made geothermal energy dramatically more cost-effective than anyone in the geothermal industry realized. Those beliefs led to a partnership with Google, a pilot project in Nevada that produced the first horizontal geothermal well ever drilled, and a 2026 IPO that raised over $2 billion. The conversation covers why geothermal has remained a rounding error in the energy mix for over a century, how Fervo reduced drilling times from 70 days to 21 days in just four years, why their process differs fundamentally from oil and gas fracking, and what milestones investors should watch as the company scales toward 500 megawatts at its Project Cape site in Utah. Things You Will Learn: Why geothermal energy has remained less than 1% of U.S. electricity despite being over a century old. How horizontal drilling technology borrowed from oil and gas is transforming the cost structure of geothermal power. Why Fervo's process is structurally different from fossil fuel fracking, even though it borrows similar techniques. How Fervo went from startup to a multi-billion-dollar publicly traded company in under a decade. Where the next wave of geothermal entrepreneurship opportunities may emerge across the value chain. Tools & Frameworks Covered: Horizontal Drilling for Geothermal: Applying directional drilling techniques from the oil and gas industry to access deeper, hotter rock formations and dramatically increase well productivity compared to traditional vertical geothermal wells. The Earned Secret Framework: The idea that successful startups are built on insights that incumbents have missed, whether because the timing was not right, the technology had not yet transferred across industries, or conventional wisdom had not caught up with reality. Investors Invest on a Line, Not a Point: A fundraising philosophy emphasizing consistent delivery against stated milestones over multiple rounds, building credibility that compounds with each stage of execution. #BusinessForGood #SustainableBusiness #CleanEnergy #FutureOfEnergy | 44m 59s | ||||||
| 8/1/26 | Did America Forget How to Build Nuclear Energy? | Nuclear energy was supposed to transform the world. Then came Chernobyl, Three Mile Island, and Fukushima, and public trust collapsed. But for 25 years, engineers across a dozen countries have been quietly designing a new generation of reactors built to fail safely without relying on human intervention or mechanical backup systems. And the target date they set back in 2000 is almost here. In this episode of Business For Good, Paul Shapiro speaks with Edward Friedman, a nuclear historian and advocate who has been writing and speaking publicly about nuclear energy since 1961. Edward walks through the misunderstandings that still shape public perception of nuclear accidents, explains why Generation IV reactor designs represent a fundamental shift in safety architecture, and lays out why the United States risks falling behind China and Russia in building the energy infrastructure the climate crisis demands. Things You Will Learn: Why Generation 4 nuclear reactors are designed to shut down on their own using the laws of physics, without relying on human operators or mechanical safety systems. How the Godzilla franchise shaped decades of public fear about radiation far beyond what the science supports. Why China has connected 55 new nuclear reactors to its grid since 2000 while the United States has connected only three. How Bill Gates' TerraPower plans to replace coal plants with sodium-cooled nuclear reactors of identical size and power output. Why training programs for nuclear technicians and support staff may be one of the biggest bottlenecks in scaling nuclear energy. Tools & Frameworks Covered: Generation IV International Forum: A multinational collaboration launched in 2000 to develop four categories of advanced nuclear reactor designs that are fail-safe, economical, and do not use water-based cooling systems. Fail-Safe Reactor Design: An engineering approach in which reactors shut themselves down through the laws of physics when overheated, using mechanisms like fluid expansion or melt plugs rather than human intervention or active mechanical systems. Coal-to-Nuclear Replacement Model: Bill Gates' strategy of building nuclear reactors sized to match existing coal plants, enabling direct replacement of fossil fuel infrastructure without redesigning the surrounding grid. #BusinessForGood #FutureOfFood #AlternativeProtein #SustainableBusiness | 37m 47s | ||||||

| 2/15/26 | Feed the People Authors on Abundance, Food Policy, and Meat Demand | Episode Summary What if the global food system isn't "broken" in the way sustainability debates usually claim, and treating it that way leads to worse decisions? Paul Shapiro sits down with Jan Dutkiewicz and Gabriel Rosenberg, authors of Feed the People, to unpack how industrial scale and trade created unprecedented food abundance, why "eat local" and small-farm nostalgia collapses at 8 billion people, and what practical policy levers can improve outcomes without fantasy. They explore a clear framework, more food, less feed, no fuel, why animal agriculture remains an inefficient use of land and protein, and how public policy can reshape meat demand by changing incentives instead of accepting forecasts as fate. You'll leave with sharper systems thinking, grounded tradeoffs, and a clearer view of what scalable food system decarbonization can actually look like. Things You Will Learn How to evaluate food system claims using systems logic instead of slogans. Why meat demand rises, and how policy can bend the curve without moralizing. What "more food, less feed, no fuel" implies for land use, emissions, and investment priorities. Tools & Frameworks Covered More food, less feed, no fuel. Prioritizes crops for human food over animal feed and biofuels. Incentives over narratives. Shows how policy choices shape production, prices, and demand. Democratic hedonism. Meets people where they are, then reduces harm at scale. #BusinessForGood #SustainableBusiness #FutureOfFood #AlternativeProtein #FoodSystemDecarbonization | 50m 07s | ||||||
| 2/1/26 | Bruce Friedrich (Good Food Institute) on Taste, Price, and What It Takes to Scale Alternative Meat | Alternative meat looks like it is collapsing. Startups are shutting down, funding is drying up, and headlines are calling the category finished, but that reaction may reflect a misunderstanding of how technological revolutions actually unfold. Bruce Friedrich, President of the Good Food Institute and author of Meat: How the Next Agricultural Revolution Will Transform Humanity's Favorite Food and Our Future, explains why most people will not change behavior for values alone, why price and taste are the real adoption gates, and why "only" $3 billion in cultivated meat funding is far smaller than it sounds when spread across years and companies. Paul and Bruce discuss what it will take to reach taste and price parity, why governments increasingly view alternative protein as food security and national security infrastructure, and why today's failures can be a normal feature of early-stage category formation rather than proof the model will not work. You will leave with a clearer, more evidence-driven view of what is happening now and what progress actually looks like. Things You Will Learn: How taste and price parity shape S-curve adoption in food, regardless of ethics or intent Why $3B in cultivated meat investment may be insufficient relative to comparable industrial innovation cycles How food security, geopolitical risk, and economic competitiveness are driving government interest in alternative protein Tools & Frameworks Covered: S-Curve Adoption – helps evaluate whether setbacks are normal in scaling technologies Eliminating the Green Premium – helps frame what it takes for sustainable products to win at mass-market scale B2B Enablement Strategy – helps identify leverage points that unlock category-wide progress #BusinessForGood #SustainableBusiness #FutureOfFood #AlternativeProtein #PrecisionFermentation | 58m 26s | ||||||
| 1/15/26 | Modern Mill's Chris Guimond on Upcycling Rice Hulls Into Low Maintenance Building Materials | Episode Summary A rice field does not look like the starting point for a scalable building materials company until you understand the economics behind it. In this episode of Business For Good, Paul Shapiro sits down with Chris Guimond, Founder and CEO of Modern Mill, to explore how discarded rice hulls are being transformed into ACRE, a wood like siding, decking, and trim product designed to replace old growth lumber. Chris explains why deforestation is a supply and demand problem, how Modern Mill cracked the manufacturing and adoption challenges that derail most composites, and what it takes to raise significant capital to build real infrastructure in the United States. The conversation covers circular economy manufacturing, competing with billion dollar incumbents, and why climate solutions scale only when they outperform existing systems on cost, durability, and ease of use. Things You Will Learn Why most sustainable materials fail at adoption and how to avoid that trap How supply chain location determines whether upcycling works economically What it takes to scale a hard tech manufacturing business in a legacy industry Tools and Frameworks Covered Supply chain proximity strategy to control logistics costs and reliability Adoption first product design for builders and contractors Capacity planning to scale manufacturing without breaking trust Episode Timestamps 05:10 – Why rice hulls present a hidden opportunity in building materials 08:56 – Cracking the code on turning agricultural waste into scalable products 13:20 – Why most composites fail to replace wood 25:20 – How logistics and location shape upcycling economics 35:10 – Scaling capacity before demand fully arrives #BusinessForGood #SustainableBusiness #CircularEconomy #ClimateSolutions #FutureOfFood | 40m 11s | ||||||
| 1/1/26 | Deep Fission: Using Boreholes to Cut Nuclear Costs and Deliver 24/7 Clean Electricity | What if the fastest path to reliable clean electricity is not a new reactor design, but a new place to put one? In this conversation, Paul Shapiro speaks with Elizabeth Muller, CEO of Deep Fission, about a plan to place a conventional pressurized water reactor roughly a mile underground to use geology, gravity, and groundwater for containment, pressure, and emergency cooling, potentially cutting total nuclear costs by as much as 80%. They unpack how a narrow borehole reactor could serve always-on demand from data centers and industrial users, what "proven tech combined in a new way" really means, how safety and groundwater concerns are handled through regulation and engineering practices, and the practical milestones from pilot to commercial operation so listeners can evaluate what it would take for underground nuclear to scale. Things You Will Learn How putting a conventional reactor in a mile-deep borehole can replace major above-ground systems and cut nuclear cost drivers. How Deep Fission thinks about worst-case scenarios, groundwater protection, and regulatory proof points. What milestones convert LOIs into power purchase agreements, and what timelines look like for early deployment. Tools & Frameworks Covered Geology-as-infrastructure – Uses rock, gravity, and water to replace containment and pressurization systems. Mature-tech recombination – Combines proven reactors, drilling, and geothermal heat transfer to speed time to market. Pilot-to-commercial pathway – Separates "go critical" demonstration from commercial electricity generation milestones. Episode Timestamps04:55 – Why a mile underground could cut nuclear costs by about 80% 08:47 – Borehole size, reactor dimensions, and how the hardware fits 09:31 – Replacement strategy, sealing, and stacking long-term operations 19:45 – Groundwater and safety concerns, what regulators need to see 21:43 – Timeline to power, DOE pilot program, and moving toward commercialization #BusinessForGood #CleanEnergy #NuclearEnergy #EnergyInnovation #ClimateSolutions | 32m 54s | ||||||
| 12/15/25 | The Incredible, Edible… Pea? How Meala is Using Biotech to Render Eggs Obsolete | If you've ever checked the ingredients on a baked good, you know how ubiquitous eggs are. They bind, they lift, they emulsify, they hold moisture — they're simply the structural engineers of cookies, cakes, and muffins everywhere. But they're also volatile: prices spike, supply chains break, and for anyone with an egg allergy or who's avoiding eggs for animal welfare or environmental reasons, eggs aren't exactly a welcome ingredient to find on the ingredient deck. Enter Hadar Ekhoiz Razmovich, CEO and co-founder of Meala FoodTech, an Israeli startup that's figured out how to make peas do what eggs and hydrocolloids do, and has consequently raised several million dollars in venture capital so far. Meala's breakthrough lies in taking simple pea protein and using advanced biotechnology to unlock its hidden abilities — creating a single-ingredient powder that they say can whip, bind, and gel just like an egg in baked goods and alternative meat. No multi-ingredient formulations, no methylcellulose, no animal inputs — just plants doing some biochemical magic. In this episode, Hadar shares how her background in R&D led her to tackle one of food science's toughest challenges: replacing eggs and hydrocolloids without sacrificing texture, taste, or cost. We talk about how Meala's technology works, what it takes to convince industrial bakeries to swap eggs for peas, and why she believes clean-label ingredients like this are the future of food. Hadar is not just rethinking what we eat, she and her team are rebuilding the food system from scratch, one cookie, cake, and croissant at a time. Discussed in this episode Meals is backed by The Kitchen Food Tech Hub, DSM's venture arm, Milk & Honey Ventures, Lasenor, and EIT. Our past episode with Milk & Honey Ventures' Beni Nofech. More on Meala's egg replacer, GroundBaker, is here. You can see two pending patent applications of Meala's here and here. Get to know Hadar Ekhoiz Razmovich Hadar Ekhoiz Razmovich brings over 12 years of leadership experience in the global food industry, with a strong focus on driving innovation and R&D across traditional food sectors.

| 12/1/25 | From Oil Wells to Oak Trees: Ben Dell's Half-Billion-Dollar Pivot to Carbon Offsetting | What if planting trees could be not just good for the planet, but also a profitable business? In this episode, I'm talking with Ben Dell, the founder and CEO of Chestnut Carbon — a company that's raised nearly $400 million, including $250 million of that in 2025, to turn farmland back into thriving native forests across the United States. And he's already forging major carbon removal deals with the likes of Microsoft and Mercedes F1. Ben's journey is a fascinating one: he began his career in oil and gas private equity, helping fossil-fuel companies optimize their operations. But during the pandemic, he had what you might call a carbon epiphany. Seeing how few trustworthy carbon-removal projects existed, he decided to create his own — one that would make measurable, verifiable, and permanent carbon storage not just possible, but investable. In our conversation, Ben explains why carbon is a commodity, and how to prove you've really stored it. He talks about how Chestnut buys up marginal cattle-grazed land and restores it into biodiverse forests — with already more than 17 million trees planted. And he goes over why he proudly calls Chestnut "conservation for profit" — a business model that needs no subsidies, just land, good science, and a lot of patience. Ben also talks about the challenges of scaling a nature-based startup, the importance of grit over glamour, and why he believes restoring forests can be one of America's most investable climate solutions. So if you've ever wondered how capitalism might actually reverse deforestation — not cause it — this episode will give you a hopeful, grounded look at what that future could look like. Discussed in this episode Ben is a managing partner at Kimmeridge. Business Insider profile and a Wall Street Journal profile on Ben's work. Our past episode with author Mike Grunwald. You can see Chestnut's patent, "Systems and methods for forest surveying," here. Chestnut's offtake partnership with Microsoft and a similar agreement with Mercedes F1. Ben recommends podcasts such as Lex Fridman's and Invest Like the Best. Get to Know Ben Dell Ben Dell is a Managing Partner of Kimmeridge and oversees investment activity across the firm. He is closely involved in the screening of new geological opportunities and in the negotiation and execution of investment strategies. Prior to founding Kimmeridge, Mr. Dell was a Senior Equity Research Analyst for Oil and Gas Exploration and Production (E&P) at Sanford C. Bernstein, where he was ranked first three times in the Institutional Investor Research Survey for coverage of E&Ps. Mr. Dell was also ranked for Natural Gas and for Oil Services and Equipment coverage. Mr. Dell joined Sanford C. Bernstein in 2003. Prior to joining Bernstein, Mr. Dell was employed at British Petroleum (BP) in its M&A and finance group.

Mr. Dell earned an undergraduate degree and a master's degree in Earth Sciences from St. Peter's College, Oxford. | 30m 50s | ||||||
| 11/15/25 | Ready for a Carpet Made of Human Hair? This Entrepreneur Turns Salon Waste into Textiles | What if one solution to fashion's waste problem is literally growing on our own heads? Every day, salons around the world toss out millions of pounds of freshly cut human hair — a clean, protein-rich, renewable resource that mostly ends up in landfills or incinerators. But what if that so-called waste could become the next sustainable textile? My guest on this episode, Zsofia Kollar, is the founder and CEO of Human Material Loop, a Netherlands-based startup turning salon hair waste into a high-performance fibre that behaves like wool — but with 43 times lower CO₂ emissions, 20 times less water use, and none of the animal cruelty or plastics. Their branded fiber, called Adara, is already being spun into things like carpets, curtains, and acoustic panels — and it's made from something we all grow ourselves. In this conversation, Zsofia and I talk about how she got the idea to build an entire materials company out of human hair, how her technology works, why hair is such a strong and versatile material, the "ick" factor of human-derived fibres, and how she's scaling her model so that salons and HML benefit alike. If you think using human hair in textiles sounds strange, stick around — because by the end of this episode, you might just want a carpet made from your own cut-offs. I'll let Zsofia make the case. Discussed in this episode Washington Post coverage of Human Material Loop's work. Vogue and CNN have covered their work, too. Zoroastrians sometimes practice sky burial on a Tower of Silence, in which vultures are allowed to consume a recently deceased human. Our past episode on human composting with Recompose. Get to Know Zsofia Kollar Zsofia Kollar is a forward-thinking entrepreneur passionate about sustainable innovation. Science and design are crucial in the company's development. After her experience running an independent design studio, Zsofia was driven to reimagine waste management, focusing particularly on hair waste.

| 11/1/25 | From Fashion Model to Fission Mission: Isabelle Boemeke's Nuclear-Powered Future | When you hear the word nuclear, does your mind flash to mushroom clouds, Chernobyl, or maybe the glowing three-eyed fish from The Simpsons? Well, what if nuclear electricity — far from being an environmental villain — is actually one of the safest, cleanest, and most land-efficient energy sources we have? It turns out that former fashion model Isabelle Boemeke is on a mission to change how we think about nuclear energy. When she and I met a few years ago, in Italy of all places, she was known by many simply as Isodope, her online persona that blends fashion, futurism, and fission to make nuclear cool again. And now, in her new book Rad Future, Isabelle argues that nuclear power isn't just misunderstood — it's essential to solving climate change, land preservation, and numerous other important concerns. In our conversation, Isabelle details: Why fear of nuclear power stems more from cultural trauma than from science, Why nuclear electricity is safer and environmentally-friendlier than not just fossil fuels, but also solar and wind, What's fact vs. fiction when it comes to the world's biggest energy disasters, And why, despite all the excitement about fusion and modular reactors, maybe the smartest thing we can do right now is simply pick a proven fission design — and start building them fast. I always love when it turns out that the thing we thought was the villain is actually a hero, or at least better than what we thought. If you do too, this is the episode for you, as this episode may challenge your assumptions about what's truly "green" and is actually safe. Discussed in this episode The 2019 Amazon Rainforest fires and Australian fires that decimated massive amounts of wildlife habitat helped inspire Isabelle to focus on environmental concerns such as climate change. The 1975 Baquiao dam collapse killed hundreds of thousands of people. Isabelle recommends checking out www.whatisnuclear.com and the Decouple Podcast. Commonwealth Fusion recently raised $863 million. The US military is investing in small, mobile nuclear reactors. Paul recently read a sci-fi book about nuclear-powered wildlife called The Kaiju Preservation Society. Get to Know Isabelle Boemeke With her signature mix of humor, sharp research, and optimistic vision, her debut book, Rad Future, makes the case for nuclear electricity as one of the best tools to solve the climate crisis. Boemeke is also known as Isodope, the irreverent digital persona on a mission to make nuclear cool. She is the Founder and Executive Director of Save Clean Energy and board member of Nature is Nonpartisan and Nuclear Scaling Initiative, where she works at the intersection of policy, culture, and technology to accelerate pragmatic solutions. She delivered a TED Talk that has been viewed nearly 2 million times, led a grassroots campaign that helped delay the closure of California's Diablo Canyon Power Plant, and is a TIME Magazine "Next Generation Leader." | 43m 15s | ||||||
| 10/15/25 | Fungi-Filled Diapers: How Plastic-Eating Fungi May Change Child-Rearing | If you've ever changed a diaper, you might've wondered what happens to it after it goes in the trash. The answer, unfortunately, is that it'll sit in a landfill for hundreds of years—certainly longer than the baby who briefly wore it will live. In fact, every diaper you wore when you were a baby is still sitting around, at best in a landfill, or perhaps even in the ocean. And did you know the average American baby goes through 6,000 diapers before learning to use a toilet? But what if fungi could change that? In this episode, I sit down with serial entrepreneur Miki Agrawal, the founder of Thinx (yes, the period underwear company), Tushy (yes, the bidet company), and now HIRO Technologies—a company using plastic-eating fungi to help disposable diapers return to the earth. Miki, who some have dubbed the "Queen of pee, poop, and periods," (I think they should shorten it to the "Queen of Secretions") shares how an opportune moment with her toddler and a children's book about fungi inspired her to launch HIRO. Her company's first product—HIRO Diapers—uses a packet of dormant, culinary-grade fungi that awaken when exposed to moisture and begin breaking down the diaper's plastic components, dramatically reducing its landfill lifespan from centuries to under a year, after which it simply becomes dirt. We talk about everything from the science of fungal degradation to the challenges of biotech entrepreneurship, from raising millions for an unconventional idea to why she believes reconnecting with nature is the ultimate form of innovation. Whether you're a parent, a sustainability enthusiast, or just fascinated by the intersection of biology and business, this conversation will make you rethink what "waste" really means. Discussed in this episode It was the children's book Pacha's Pajamas that implanted the idea in Miki's mind about plastic-eating fungi. You can buy HIRO Diapers here. You can see HIRO's original kickstarter, including video pitch, here. Miki recommends checking out the UN Millenium Goals for ideas of companies to create. Reuters discusses HIRO's launch and technology. Miki also started Thinkx (period underwear) and Tushy (bidets). More about Miki Agrawal Miki Agrawal is the creative force behind acclaimed social enterprises TUSHY (the modern bidet brand), THINX (period-proof underwear), and WILD (NYC's first gluten-free pizza concept), collectively valued at over $250 million. Miki is the author of best-selling books "DO COOL SH*T" and "DISRUPT-HER". Her latest company HIRO is a revolutionary nature-based start-up harnessing ancient technology - fungi - to help solve the global plastic crisis. Their first product is a baby diaper that returns to the earth with the help of friendly fungi. (They chose diapers to launch with because they're the #1 household plastic waste item that takes 400+ years to decompose in a landfill - and each baby uses ~6,000 diapers in their lifetime. Wild, right?) HIRO Diapers starts returning to the earth with the help of fungi - and they're soft, safe, high-performing and ready to change the game. Recognized as one of Fast Company's "Most Creative People," a "Young Global Leader" by the World Economic Forum, and named one of INC's "Most Impressive Women Entrepreneurs," Miki brings a wealth of experience and expertise to the stage as a keynote speaker. Her authentic talks have been validated by audiences at MindValley, EO, and Capitalism.com, who have voted for her as the #1 best speaker among hundreds of speakers. | 40m 36s | ||||||
