Hringvarmi is a circular Ag tech startup co-founded by Justine Vanhalst and Dr. Alexandra Leeper. The Hringvarmi solution, harnesses excess heat from data centres and channels it into purpose-built biomes that provide space and infrastructure for controlled environment food production. Our solution aims to solve multiple intersectional challenges with one circular economy solution while creating a vibrant community for food producers. The solution is being test-driven in Iceland, a country where 80% of the fresh fruits and vegetables are imported, a significant carbon footprint and where a sustainable minded data centre sector is flourishing.
