Feedkind®, the new protein to address the dual challenge of food security and climate change

Aquaculture growth is requiring more protein for feed in order to follow consumer demand. Existing protein sources are coming either from animal
or vegetal origin; increasing their production would be adding pressure
on natural resources of the planet. Calysseo is offering a sustainable protein that have minimal impact on the planet resources: arable land, water consumption and halieutic population.

a nutritious, non-GMO protein by fermentation.
