Poseidona is removing invasive algae from oceans and turning it into food


Poseidona is a Barcelona-based developer of sustainable food technology. It takes invasive seaweed and algal side-streams to make proteins. In this case, it's a soy protein alternative.

They founded Poseidona, a Barcelona-based developer of sustainable food technology, which uses that invasive seaweed and algal side-streams — the waste that agricultural producers generate — to make proteins. “We also have a project ongoing specifically caring for the organoleptics of the product, ensuring it won’t have any ‘spoiled seaweed’ flavor and it will have a good color,” she told TechCrunch. There’s also Berlin-based Pacifico Biolabs, which announced$3.3 million in pre-seed funding last month for its fermentation process to make alternative seafood.
