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? 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 , 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...

Business for Good Podcast

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.

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...

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 MicroHarvest, 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 a mission to reshape how the world thinks about protein production. Rather than growing plants or animals, they grow single-cell microbes in bioreactors, yielding a high-protein, micronutrient-rich ingredient that can be used in everything from animal feed and pet food to, eventually, human food.
With 10 million euros raised and hopefully a new 30 million euro round on the horizon, their process is fast, efficient, and radically resource-light—requiring far less land, water, and energy than traditional agriculture. Already able to produce one ton of their product per day, MicroHarvest is proving that microbial protein isn’t just a lab experiment—it’s a scalable, real-world solution.
In this episode, Kate shares what it takes to bring biotech innovation to market, and why she believes protein production should be faster, cleaner, and closer to the consumer. We talk about the company’s entry into pet food and aquaculture, and what the future holds for sustainable protein made from the tiniest organisms on Earth.
If you’re curious about the future of food, circular economies, or how to build a business that’s good for animals and the planet, this conversation is for you.
