Bruce Friedrich (Good Food Institute) on Taste, Price, and What It Takes to Scale Alternative Meat
Business for Good Podcast
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...

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...

The Incredible, Edible… Pea? How Meala is Using Biotech to Render Eggs Obsolete
Business for Good Podcast
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 , an Israeli startup that’s figured out how to make peas...

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

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...

Business for Good Podcast
Recently had me as a guest on his show, the to talk about ’s . When it came out, more than one Business for Good listener heard it and told me they thought it would make a good episode to release to our audience too, so this episode is simply the conversation Alex and I had for his podcast. If you’ve been following the alternative protein sector (and the broader biotech sector), you’ve likely seen the wave of challenges that fermentation, cultivated, and plant-based startups have faced over the past few years. As recent reporting confirms, ag and food tech investment is at a...

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...
info_outlineWhat 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.
