Earth Kiln By High Plains Biochar

Endorsed by CSI -
Designed for the Global South

Formerly known as "The Big Boy"

Carbon Standards International (CSI) Certification

The Earth Kiln by High Plains Biochar is now officially endorsed under the Global Artisan C-Sink Standard, making us one of the few technology providers worldwide to achieve this recognition.

Why choose the Earth Kiln?

Reduced Emissions

Low Methane Emissions: Produces only 1.8 kg of methane per ton of biochar, compared to 30 kg per ton from traditional open-pit or Kon-Tiki kilns.

Maximize Carbon Credits: Lower emissions mean more carbon credits can be generated from the same volume of biochar production.

Reduced Environmental Impact: In addition to lowering methane emissions, the Earth Kiln significantly reduces other harmful emissions, making biochar production cleaner and more sustainable.

Improved Safety

Operator Protection: The kiln’s enclosed design protects operators from open-flame heat, smoke, and particle exposure, minimizing potential health risks.

Fire Containment: Fully contains the fire, preventing windblown embers, reducing wildfire risk, and allowing safe operation even in windy conditions.

Value of Low Methane Kilns

Methane is a very powerful greenhouse gas — about 86 times stronger than CO₂ over 20 years.
Traditional Kon-Tiki kilns emit ~30 kg CH₄ per ton of biochar, which equals ~38 tCO₂e of warming effect.
High Plains Biochar’s Earth Kiln emits only 1.8kg CH₄ per ton (2.3 tCO₂e)
That’s a 95% reduction.

Why this reduction is valuable

With Kon-Tikis, projects need to “compensate” for those methane emissions to meet crediting standards. That usually means:

Proving avoidance (showing biomass would otherwise have been burned).
Retiring C-Sink20 credits from other projects.
Or buying other offsets (like tree planting).

This adds cost and paperwork. With the Earth Kiln, methane is already so low that no extra scheme is needed and projects can claim the full credits directly.
