Nutrition, Nitrogen & circular systems with Dr Pia Winberg

Season 1, Ep. 5

This episode’s for you if you’re into eating seaweed, sustainable food systems, Nitrogen cycles, how seaweed can heal burns, or if you’ve ever daydreamed about being a humble seaweed farmer 🧑‍🌾🍝


Dr Pia Winberg is a marine ecologist who’s spent the past 25 years working in and researching sustainable marine development. In her words, she’s now in “the business of growing seaweed in a circular economy” and her main focus is developing systems to sustainably cultivate seaweeds in Australia. She runs two companies, Phycohealth and Venus Shell Systems, she has seaweed products on the shelves of supermarkets and she’s currently testing the wound-healing properties of seaweed cells. 


You can find Pia at Phycohealth or Venus Shell Systems and on social media @phycohealth. You can find and contact me @seaweed.people
