Step 1<\/h4><\/div><\/div><\/div><\/div>

The Kon-Tiki <\/h2><\/div><\/div>
<\/div><\/div>

A simple pit can be used as a Kon-Tiki to produce biochar. This is a cone-shaped hole in the ground in which biomass is placed in layers. in layers<\/em> <\/strong>is burned in layers. The special design and controlled oxygen supply create a pyrolysis process in which the biomass only partially burns and is converted into biochar. The Kon-Tiki process is cost-effective and is particularly suitable for small farmers or communities who want to produce biochar without industrial facilities.

The fuel<\/h2><\/div><\/div>
<\/div><\/div>

Organic biomass such as wood, straw, husk residues, leaves or agricultural waste is used to produce biochar. It is important that the material is as dry and uniformly thick as possible, as this enables even combustion and optimum pyrolysis. A uniform thickness of the biomass layers promotes a constant temperature distribution in the combustion chamber and prevents incomplete charring or the formation of ash instead of coal. <\/p>\n<\/div><\/div><\/div>

IMPORTANT<\/span><\/h3>\n

Do not use wood that is heavily contaminated with pesticides.
Pollutants may not be completely incinerated and then re-enter the soil.<\/em><\/span><\/p>\n<\/div><\/div><\/div><\/div>

Step 3<\/h4><\/div><\/div><\/div><\/div>

Burn correctly<\/h2><\/div><\/div>
<\/div><\/div>

During the burning process, the evenly thick, dry biomaterial is filled into the conical pit (Kontiki) in layers and ignited.
Due to the conical shape and the limited oxygen supply, each layer only burns partially and chars in the process. As soon as a layer has turned to embers, a new layer of biomass of the same thickness is placed on top.
This layer structure ensures controlled pyrolysis, in which the material slowly and evenly turns into charcoal without burning completely to ash. <\/p>\n<\/div><\/div><\/div>

IMPORTANT<\/span><\/h3>\n

Burning must take place in layers, i.e. in many layers, otherwise the burning process is not clean and the material may burn and not char.<\/em><\/span><\/p>\n<\/div><\/div><\/div>

INFO<\/span><\/h3>\n

If combustion, i.e. burning in layers, is done correctly, no smoke is produced during combustion<\/strong>. The fire does not smoke, as can be seen in the picture (left).<\/strong><\/em><\/span><\/p>\n<\/div><\/div><\/div><\/div><\/div>

Extinguishing<\/h2><\/div><\/div>
<\/div><\/div>

After the burning process, the glowing charcoal in the Kontiki is extinguished with water from below. This step is important because it stops combustion immediately and cools the charcoal, preventing it from burning further into ash.
Quenching also binds moisture in the charcoal, making it easier to work into the soil later. <\/p>\n<\/div><\/div><\/div>

INFO<\/span><\/h3>\n

A Kon-Tiki of this size requires approx. 50 to 100 liters of water.
The best way to do this is to use a hose to feed the water into the Kon-Tiki from the sides first.
