Footprint Co-founder and CEO Troy Swope leads world-class engineers, scientists, environmentalists and designers on a mission to create a healthier planet, with step one to provide sustainable alternatives to single-use plastics.

In this interview, Rob makes his case for more technological innovation in food, not less, including finding ways to reduce the number of animals humanity is raising for food. I found his book eye-opening and hope you’ll enjoy hearing his perspective on food sustainability in this new interview.

Katrina Spade is on a mission to offer a better way to deal with human corpses, and it involves a process called natural organic reduction. It’s essentially a fancy way of saying she’s invented a method of accelerated composting for your body. Rather than cremating your corpse, which involves substantial pollution, and rather than burial, which typically means sealing your body off from nature with concrete liners, hermetically sealed caskets, preservatives in your body, and more, Katrina wants to turn your body into healthy, rich soil, within just one month.

Radical Plastics is essentially asking the question: what if all that plastic lining our highways or floating in the ocean would actually biodegrade? That’s the promise of the technology that they’re pioneering. They’ve discovered a mineral concoction that when added during the manufacturing of conventional plastic—at even less than one percent—will eventually convert that plastic into food that microbes will recognize and eat.

For the past 2+ years, I’ve often said that I may be the face of our company, but Doni is the backbone, serving as our Executive Vice President and overseeing all of our operations and logistics. She’s truly integral to the enterprise, and in this episode, Doni shares her secrets about what she’s looking for in job applicants, what the transition from nonprofit exec to scrappy startup has been like, how she thinks about compensation packages in Startupland, and more.

Their goal: to be the Good Food Institute of animal-free materials, helping to attract investment and entrepreneurial activity to build a new industry of animal-free fur, leather, silk, and more.

Mélanie Broyé-Engelkes is the CEO of Ananas Anam, makers of Piñatex. It’s a leather alternative that’s made from the leaves of the pineapple plant, which are typically considered an agricultural waste product. These upcycled leaves are converted into a functional and luxurious-feeling material that can be used for everything from shoes to handbags, and more.

What if we could take a lot of trash and seed it with fungal cultures that would eat it and render it no longer toxic within just a few weeks rather than having to wait centuries? That’s exactly what Mycocycle is planning to do, and we’ve got their CEO, Joanne Rodriguez, on the show to talk about it.

David Breslauer is the co-founder and Chief Scientific Officer of Bolt Threads. He leads technology innovation at Bolt, creating and incubating biomaterials for improved consumer products. His obsession with biomaterials began with graduate research on silk during his Bioengineering Ph.D. at UC Berkeley and UCSF.

After successfully experimenting for months in their backyard with materials given to them by a refinery, Nick and Thomas went on to found their start-up, got accepted to the prestigious Techstars accelerator, won a quarter-million dollar grant from the National Science Foundation, have filed for provisional patents on their process, and have now raised hundreds of thousands of dollars from investors. In short, they’re ready to get to work.

If you’ve ever wondered what happens when you donate a bag of goods to Goodwill, what happens to the things that don’t sell, and what happens if you try to reclaim a donated item, this episode will answer all your questions. On this episode we’ve got Goodwill exec Lori Dearwester to tell us how it all works.

There are few people with more credible voices on police reform than Brooklyn Borough President Eric Adams. As you’ll hear in the interview, Adams talks about how his experience of being beaten by the police while in custody as a black teenager led to him become a police officer himself for two decades, and then ultimately to a life in politics.

One serial entrepreneur, Rich “Raz” Razgaitis, is trying to make plastic-free tap water cool again, and wants you to think of single-use plastic water bottles as if they were as socially unacceptable as cigarettes. And so far he’s raised $25 million in venture capital to wage his purified tap water crusade.

You’ll hear in this interview what role Isha Datar thinks nonprofits like hers should play in a nascent industry whose start-ups are attracting hundreds of millions of dollars of venture capital. As well, Isha discusses the fact that many of the people now working at cell ag start-ups have come through New Harvest and its ecosystem.

In many countries, walking down city streets vividly brings to life two serious problems: plastic pollution and poverty. While there are charities trying to address both of these concerns, serial entrepreneur David Katz in 2013 thought there was an opportunity to marry the two issues and build a profitable business out of it. The result: Plastic Bank.

Rodrigo Garcia Gonzales and Pierre Paslier began ordering ingredients off Amazon and Alibaba and tinkered away in their kitchen. With a rough prototype in hand, they decided they’d launch a Kickstarter to see if there was interest in a new company that would make alternative packaging from seaweed. The result: A million dollars poured in and Notpla became a reality.
