The Company

The society is very dependent on fossil fuels, and almost everything we do has a carbon footprint. Our natural resources are running out and we need to go from linear to circular use. The negative consequences of our fossil dependency are obvious and a transformation into a fossil-free society is urgent.

Cortus has the solution for transforming the fossil dependency into independency. We do it by closing the loop and converting waste into renewable energy!


Cortus was founded by Rolf Ljunggren in 2006 with the vision to revolutionize the energy market with new green technology. The company is listed on Nasdaq First North Growth Market in Stockholm since 2013.

Cortus business idea is to replace fossil fuels and chemicals with renewables. We do it cost-effectively, on an industrial scale and on a global market. Our mission is to help our customers in their transition to renewable production.

We are 30+ employees representing several different nationalities and speaking more than 10 languages. We have a very skilled team with top level expertise within engineering, process, operation and project management. Our common driving force is to reduce the climate impact and contribute to a sustainable society!

At Cortus, we contribute to the UN Sustainable Development Goals in our daily work by developing green and clean technology.
