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...

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?

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...

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...

Turning Plants into Plastic-Free Packaging: The Xampla Story
Business for Good Podcast
Plastic pollution is one of the defining environmental challenges of our time—microplastics are now found in our oceans, our soil, our drinking water, and even in our bloodstreams.

Born out of the University of Cambridge, Xampla is a materials science innovation company that’s developed a new class of plastic-free, fully biodegradable materials that offer a drop-in replacement for the most polluting types of plastic. Their flagship line, known as Morro™,...
info_outlineWhat if the fat in your butter, cheese, or even burger could be made without animals, without plants, without fermentation, and without agriculture at all? That’s exactly what Savor is doing. Using a groundbreaking process that transforms compounds like CO₂ and elements like hydrogen into rich, animal-free fats that can mimic what animal fat does, this California-based startup is rethinking how we produce and consume one of the most essential ingredients in food.
In this episode, I sit down with Kathleen Alexander, cofounder and CEO of Savor, to dive into the science behind their innovative fat production, why alternative fats could be the next big breakthrough in food tech, and how their approach could help fight climate change while making all types of foods, including plant-based meats and dairy, taste even better.
So far the company has raised more than $30 million in venture capital, including from Bill Gates, and is now gearing up to start selling its new fat in restaurants and bakeries within 2025.
Will humanity be able to divorce food production from agriculture? If Savor succeeds, that just might be the case.
