There are four configurations of the Kon-Tiki 1.2m production model:

1-Just the cone on 3 legs (it easily tips over 2 of the legs)

2-Cone with heat shield

3-Cone with cradle

4-Cone with cradle and heat shield

Prices will soon be finalised plus more photos of different configurations eg. Cones on wheels for easy transportation, a larger Kon-Tiki 1.65m

Shipping is additional cost

The Kon-Tiki biochar kiln is the fastest, cleanest way to make substantial batches of biochar from local unprocessed biomass, and condition it for application.


The Kon-Tiki deep-cone flame-curtain process was developed by Dr Paul Taylor (author of 'The Biochar Revolution' book) and Hans-Peter Schmidt at the Ithaka Institute in Switzerland in 2014. By 2016 its use has been recorded in 57 countries. The kiln was named Kon-Tiki after the Peruvian sun God, and inspired by the voyage of discovery of the Kon-Tiki raft Thor Heyerdahl sailed across the pacific.





  1. Low cost, simple and elegant compared to other biochar production technologies.

  2. Proven, high quality biochar – fulfills all conditions for the European Union Premium Certificate for biochar.

  3. The natural vortex dynamic of the Kon-Tiki cone kiln supports an “air-curtain” and flame cap that pyrolyzes the feedstock, burns the smoke and protects the char.

  4. The Kon-Tiki has tested lower air emissions compared to other low cost kilns.

  5. Rim shield provides safety, and heat protection, as well as clean combustion and uniform biochar.

  6. Low feedstock processing requirements compared to other technologies.

  7. Accepts a range of feedstocks, including mixed feedstocks and higher moisture content feedstock, in sizes from small off-cuts, through hog fuel and limb wood up to 4ft in length and 6in diameter.

  8. A high volume of biochar can be produced in a few hours (up to 1.5 cu yd batch size). The volume yield is about 45% and mass yield about 17%, comparable to other kilns and gasifiers that produce a high temperature biochar.

  9. A bottom drain allows flooding the kiln for a full, safe quench of the hot char. Hot quenching washes the char, reduces condensates (tar), and increases activity, pore volume and surface area.

  10. Nutrient charging can be conveniently done during charring, quenching or post-production right in the kiln. Add, eg. sea minerals such as liquid kelp or SEA-90, molasses, blood and bone et al

  11. The kiln comes complete with screwed legs or a sturdy tilting cradle (useful for the Kon-Tiki 1.65m) that allows the biochar to be easily tipped.

  12. Quenching liquid and nutrients can be easily captured and recycled or used for multiple purposes. Can be done with an IBC and 12V water pump with battery, which can be charged from a solar panel

  13. Agronomic trials show the Kon-Tiki system to be especially effective for improving crop yield.

  14. Relatively little training required to safely and effectively use the Kon-Tiki.

  15. Clean up your property, and enjoy the fire while making valuable biochar.

  16. The Kon-Tiki provides about 300kW of heat from biochar production, which can be developed for other purposes (e.g. cooking, water purification, drying, distillation of essential oils etc.)
