Ready for a Carpet Made of Human Hair? This Entrepreneur Turns Salon Waste into Textiles
Business for Good Podcast
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 , 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...

From Fashion Model to Fission Mission: Isabelle Boemeke’s Nuclear-Powered Future
Business for Good Podcast
When you hear the word nuclear, does your mind flash to mushroom clouds, Chernobyl, or maybe the glowing three-eyed fish from The Simpsons?

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 , her online persona that blends fashion, futurism, and fission to make nuclear...

Fungi-Filled Diapers: How Plastic-Eating Fungi May Change Child-Rearing
Business for Good Podcast
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...

Bottling the Sky: Aircapture’s Carbon Capture Breakthrough
Business for Good Podcast
When you think about climate change solutions, your mind might go to renewable energy, electric vehicles, or eating less meat. These are all of course important. But even if we stopped all emissions today, we’d still have too much CO2 in the atmosphere and would need to pull a lot of our emissions out of it. That’s the bold mission of , a California-based company pioneering modular direct air capture technology. On this episode, I speak with , Aircapture’s founder and CEO, about how his company is not only working to reduce atmospheric CO₂, but also profitably supplying it to...

Inside Mighty Earth: Glenn Hurowitz on Transforming the Meat Industry
Business for Good Podcast
What if the biggest environmental culprits were hiding in plain sight—right on our dinner plates? While most environmental organizations train their sights on the energy sector, Mighty Earth has taken a bold, and often lonely, stand in confronting the meat industry’s massive role in climate change, deforestation, and biodiversity loss. In this episode, I sit down with Glenn Hurowitz, founder and CEO of , to unpack why the meat industry typically gets ignored by the environmental movement, and what he thinks needs to be done. Glenn has spent decades fighting for the planet, from...

Turning Waste into Bioplastic Gold with Genecis CEO Luna Yu
Business for Good Podcast
It’s rare that we contemplate where all the plastic we throw out goes, but rest assured that nearly none of it is being recycled. Simply put, it’s usually cheaper to make new plastic than to recycle old plastic, even the plastic you put in the recycling bin. Because it takes plastic centuries to break down, this means for each one of us you could build a mountain of plastic from all the packaging we use over the course of our lives. But what if plastic didn’t have to take centuries to break down, and could actually biodegrade in a matter of days or weeks? That’s exactly the...

Microbial Might: Can MicroHarvest Replace Animals in Pet and Livestock Feed?
Business for Good Podcast
What if we could grow nutritious, sustainable protein—not in months or weeks—but in just one day? This episode’s guest is doing just that. Rather than going big with animal agriculture, MicroHarvest is going small with microbial agriculture. A huge number of animals are used to feed both our pets and the animals we raise for food. Kate Bekers, the CEO and co-founder of , is seeking to change that. She’s running a fast-rising European biotech startup using fermentation to produce high-quality protein from microbes—in just 24 hours. Based in Hamburg and Lisbon, MicroHarvest is on...

Business for Good Podcast
In this episode, I’m joined by one of America’s most thoughtful national journalists: Mike Grunwald.

In this sweeping and deeply reported work, Mike tackles one of the most uncomfortable truths of our time: our global food system, especially animal farming, is a...
info_outlineIn this episode we’re diving deep into the fascinating world of carbon recycling with a trailblazer who’s reshaping how we think about waste and sustainability.
Our guest is Dr. Jennifer Holmgren, CEO of LanzaTech—a company on a mission to transform our biggest environmental challenge into an economic opportunity. LanzaTech is pioneering a process that takes industrial emissions—the kind of harmful gases that typically contribute to climate change—and recycles them into valuable products like fuels, fabrics, and everyday consumer goods.
The concept might sound like science fiction, but it’s already science fact. LanzaTech’s technology captures carbon emissions from sources like steel mills, refineries, and even municipal solid waste, then feeds those emissions to specially engineered microbes. These microbes act like tiny factories, converting carbon pollution into useful materials. Imagine jet fuel made from industrial waste or yoga pants created from captured carbon—it’s not just possible; it’s happening. In fact, at the very end of 2024, LanzaTech received a holiday gift from the federal government: a $200 million award from the Dept. of Energy.
In this episode, Jennifer and I discuss the path LanzaTech took, including raising $400 million and taking 13 years prior to commercializing its first product. We also touch on her personal journey from her birth in Colombia to her taking the helm at LanzaTech.
As you’ll hear, this isn’t just about reducing emissions; it’s about completely rethinking the role of waste in our economy. LanzaTech’s vision is one where carbon is no longer a liability but an asset—a resource that can be reused and recycled, over and over again. It’s a powerful example of how businesses can align profitability with purpose, and it’s precisely the kind of story that inspires hope in these challenging times.
So, whether you’re an entrepreneur, an environmentalist, or just someone curious about the future of our planet, this is a conversation you won’t want to miss.
