What is biochar?

Biochar is a solid product obtained in pyrolysis of biomass. It is a carbon-rich and porous material which can be used for a wide range of applications, among which soil improvement, remediation and pollution control take the most important roles.

As a product, biochar differs from charcoal, which is produced at lower temperatures and considered as solid fuel, containing high quantity of volatile matter. Because of higher process temperatures, the chemical structure of biomass changes and content of hydrogen, nitrogen and oxygen in biochar is significantly decreased in relation to carbon. In contrary to charcoal, biochar is also not phytotoxic.

Biochar is mainly used in agriculture to enhance soil fertility, improve plant growth, and provide crop nutrition. As a result, it improves the overall farming productivity. It has also gained considerable attention in livestock farming as an animal feed.

What are the biochar markets?

  • soil additive: water retention product (hydrochar)
  • soil conditioner: nutrients carrier
  • soil remediation assistant
  • precursor for activated carbon
  • filtration / decontamination material
  • animal feed additive

Biochar is made from range of biomass types which allows to give them different physical and chemical properties.Content of fixed carbon, ash, volatile components, share of lignin, cellulose and chemicellulose, moisture content, average particle size and many more factors can be considered important for the final product characteristics.

Final properties of biochar can be controlled by adjusting the pyrolysis conditions. It has been proven that temperature of process and residence time are taking significant role in obtaining the properties of final product. Biogreen® system for biochar production is made for producing high quality, stable quantity of industrial biochar from variety of biomass. Depending on the biomass properties and end customer demand, our technology allows you to change the operating conditions (temperature, dwell time) within wide range of values, so you can navigate the pyrolysis process and reach expected results.
