I’ve been really curious about seaweed. I hear a lot about seaweed-based businesses, and there’s a lot of hope and hype around the potential for seaweed as a climate solution. The seaweed market has grown to become a $15 billion industry and it's projected to grow to $25 billion by 2028.  

To learn more, I caught up with two aspiring seaweed startup founders: Alexia Akbay and Julia Marsh. Their companies couldn’t be more different – one is using seaweed to eliminate plastic packaging and the other is feeding seaweed to cows so they burp less. This conversation helps highlight the range of possibilities for seaweed, what’s so special about seaweed to begin with, some of the challenges seaweed startups are facing, and a spicy question that helped me understand one of the more radical seaweed ideas floating about these days. OK, I promise no more puns, or maybe just a couple, but lots of insights to chew on. Enjoy!
