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...
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.
