Episode Details

In Fredericton, SeaGreen Solutions is turning Atlantic seaweed into a game-changing soil booster using pyrolysis to create nutrient-rich biochar. This ocean-fueled amendment soaks up moisture and slowly releases key minerals like magnesium and potassium, helping combat drought-prone clay soils in New Brunswick. Co-founder Marie Dankworth, a PhD student with global seaweed expertise, launched the company to unlock this local marine resource’s potential. The City of Fredericton is already piloting the biochar in downtown flower pots, testing its water-retention power—and if successful, could slash watering costs and scale up for broader use.
