Circular Carbon

Circular Carbon produces and supplies biochar in large, scalable quantities.

3 approaches


Biochar stores water and nutrients like a sponge. Its storage capacity is 2.5 times its own weight. Nitrate leaching also decreases by 40% on average thanks to these characteristics of biochar.


Thanks to the negatively charged surface, minerals can dock and the cation exchange capacity in the soil is increased. Nitrogen compounds are bound and therefore available to plants, and the formation of nitrous oxide after rainfall is greatly reduced. Nutrients remain available in the soil for longer. Biochar contains a whole range of important trace elements and nutrients. It is also considered an organic solid fertiliser according to the new EU fertiliser regulation.


Biochar has very high conductivity, which accelerates the exchange of electrons between enzymes and thereby increases the redox potential. Bacteria and enzymes use the biochar as a catalyst so biomass is converted into humus faster. A bacterial film of healthy soil bacteria forms around the biochar, as all the conditions for reproduction are met: water, nutrients, habitat and good reaction conditions.

Important benefits include:

  • Improved utilisation of introduced feeds with qualitatively and quantitatively better output.
  • Fewer passes/ha for tillage
  • Reduced need to use industrial fertilisers
  • Reduced use of pesticides due to higher microbial activity and a better immune response from crops
  • Increased creation of organic humus
  • Improved quality of farm manure
  • Prevention of new resistances
  • Better resistance to stress for soils and crops
  • Agricultural production can be stabilised as climate impacts increase (e.g. reduction of drought stress)
  • Reduction of the amount of nitrate and phosphorus leached into groundwater
  • Improved carbon footprint of agricultural production

Application fields

Biochar for soil improvement

In most soils, the carbon content has become so low that a self-renewing living humus soil can only be built up with considerable effort and over several generations.

Health and vitality for animals

Biochar is a valuable ingredient for animal feed. It is used as a feed additive or supplement and increases animal welfare.

Exploiting the potential

Biochar can be used in many sectors and is highly adaptable through special treatment. In order to make use of its full potential we are conducting research on a continuous basis and are checking new applications.
