About us
and what drives us

Our motivation

We want to position biochar as a driving force behind the circular economy and integrate it into different markets.

Therefore, we are producing biochar from organic residues, creating innovative solutions to restore the lost natural balance in agricultural soils.

“When we saw this one banana plant shoot out of the resulting pile of biochar our interest in biochar was really piqued.”

Peik Stenlund, Co-Founder

Our founding

Our team is driven by the vision of a sustainable economy and a healthy planet.

Circular Carbon was founded in 2018 by Lasse Gunnerud (Norway), Julian Pertwee (England), Peik Stenlund (Finland) and Felix Ertl (Germany).

We were all fascinated by the idea of using biomass residues in the circular economy. Peik Stenlund and Felix Ertl developed the Circular Carbon approach while at university in Sweden.

Hands with biochar

Projects in Uganda

Between 2010 and 2014, they realised five projects in Uganda, where they converted maize cobs into bioenergy and supplied mini-grids and maize mills in rural regions with electricity. This initiative was promoted by SIDA, the World Bank and UNIDO.

At that time, biochar was produced incidentally as a by-product of electricity production from the pyrolysis plants. “When we saw this one banana plant shoot out of the resulting pile of biochar our interest in biochar was really piqued,” says Peik. “From then on, biochar has completely gripped me!” reports Felix. With further funding, an agroforestry programme was established that made it possible to investigate the benefits of biochar in the field.

“In the following years, more and more scientific studies showed the huge potential of biochar in agriculture. Today, we’re operating the first industrial plant and are much closer to our goal to make regenerative agriculture a reality.”

“Today, we’re operating the first industrial plants for using agricultural residues and can thus make regenerative agriculture a reality.”
