About us

Circular food production

Johannas® design, build and operate sustainable circular food production systems. At the core of our systems we have fish, bacteria cultures, vegetables and insects collaborating in natural processes.

Our unique and highly experienced team allows us to take a holistic approach to food production, with data driven and automated production that makes it possible to scale up and replicate large-scale, circular, indoor farms.

Research and development

We do research and development on our processes and systems. Some of the R&D we perform together with a number of partner organisations. Read more about it on our website (partially in English) - Cirkularodling.se


Designing and running a circular food production requires a lot of knowledge and long experience. Over the years, we have built up our expertise in: raising fish, growing vegetables, agriculture, water chemistry, eco systems, sales, marketing, business and accounting, law and regulations, project management, food safety, technical systems such as pumps, sensors, HVAC, manufacturing and information technology, as well as computer software development.
