This Vertical Farm Grows Carbon-Neutral Algae Next to a Geothermal Power Plant
Vertical farms are popping up everywhere from Pennsylvania to Dubai, most of them growing some sort of leafy green (and one growing mushroom fungus!). A farm in Iceland has taken a different direction, both in terms of what it grows and how it’s growing it. Vaxa Technologies is cultivating spirulina algae indoors, and a new study found that its process is carbon-neutral and emissions-free.
