Biochar production by pyrolysis

The pyrolysis reactor – technique and comparison

The pyrolysis reactor is fed with biomass from top while air is supplied through the bottom part. Inside the reactor the biomass is heated and undergoes chemical and physical processes being transformed into biochar. By-products of this pyrolysis process are syngas (synthesis gas) and pyrolysis oil.

Our pyrolysis reactors integrate a certain number of retorts into one functional system. By that we achieve a stable, nearly continuos, output of biochar, syngas and pyrolysis oil.

Biochar – fields of application

In contrast to the waste biomass used for input the resulting biochar is of economic value.

Depending of kind and structure of the operating company biochar may be used the for its own purposes or sold nationally or internationally

Animal husbandry:  feed additive, stable bedding

Adding small amounts of biochar to the feeding of animals (e.g. pigs or chickens) will improve their growth and health. At the same time fewer antibiotics are needed and the number of pathogenic germs in the excrements is reduced.

The biochar may be used as (additive to) stable bedding to improve hygiene and to reduce likeliness of diseases. The mixture of manure and biochar than may be applied to soils.

Soil improvement

An important application of biochar is the soil improvement or the remediation of degraded soils. By its high specific surface area biochar can retain water and stores dissolved nutrients encouraging smooth and continuous growth. Biochar at the same time increases soil aeration and reduces nutrient leaching. Activated biochar enhances bacterial activity and biodiversity in the soil and is an important component of the well know Terra Preta (a very fertile humus layer).

(Waste) Water treatment

Biochar can directly be used as filter material in the water treatment. In the form of activated charcoal it is more reactive. It may be used in the treatment of drinking water as well as waste water to reduce the concentration of pollutants.

Steel industry

Even if contaminated strongly biochar may still be useful in the steel industry.

CO2 Storage

Using biochar for soil improvement has another positive aspect: Because it is so stable “CO2” is stored in the soil for a very long time (several hundred years). Therewith the carbon is withdrawn from the atmosphere slowing down the climate change.

Suitable biomass

The pyrolysis reactor is very flexible in respect to the biomass applied: it’s tested with more than 100 different kinds of biomass.

  • Waste biomass from palm oil industry (empty fruit bunches, palm kernel shells)
  • Bamboo
  • Remains of the production of coconut, cotton, pineapple, …
  • Wood chips
  • Digestate of biogas plants
  • Organic waste
  • and many others
