Brussels-based ECLO picks up bread from Bio-Planet stores and mixes it with sawdust to create a growing medium. That substrate is packed into bags and pasteurized, after which mycelium is added and mushrooms start growing. After four to twelve weeks, ECLO harvests organic eryngii and nameko mushrooms, which are then sold at all of Bio-Planet’s stores.
