This plant-based fertilizer can be grown on wastewater

Half of the world’s population depends on fertilizer for the food they eat - but producing that fertilizer generates staggering amounts of CO2. Step up Fyto, whose sustainable fertilizer takes a nuisance aquatic plant - duckweed, or Lemna - and turns it into protein-rich food for crops. Duckweed happens to be packed with nitrogen and can double its biomass in just 2 days. Food systems generate a third of global emissions - but 1 in 11 people worldwide still go to bed hungry. The Food Innovation Hubs Global Initiative aims to scale solutions that make our foodsystem more effective and sustainable.
