Key Features

Designed For Maximum Value & Zero Emission Carbonization

Why Adopt the CLIMATAG Retort Kiln?

  • Closed sealed retort design prevents direct ash burning of biomass.
  • Syngas recirculation channels gases back into the combustion chamber as fuel.
  • ECO models feature extended water heat-exchangers for pyroligneous acid (wood vinegar) condensation.
  • Provides dual benefits of biostimulant production and hot water generation.
  • Available in standard 40 Kg and heavy-duty 70 Kg batch capacity options.
  • High carbon purity output suitable for soil health, bio-fertilizers, and filtration.

Operation Process

How Retort Pyrolysis Works

Indirect heating. Syngas combustion. Byproduct harvesting.

1

Seal Retort Chamber

Load dry biomass into inner retort vessel and seal securely to eliminate oxygen contact.

2

External Thermal Heating

Initiate combustion in outer jacket, indirectly heating inner chamber to thermochemical reaction temps.

3

Syngas & Heat Exchange

Recirculate wood gas to sustain burn; ECO models route condensables through water heat exchangers.

4

Collect Biochar & Byproducts

Harvest premium fixed-carbon biochar along with liquid Wood Vinegar and Hot Water (ECO models).

Agronomic Impact

Soil & Yield Benefits of Retort Biochar

  • Higher fixed carbon content (>75%) due to indirect pyrolysis.
  • Retains key mineral nutrients without ash dilution.
  • Wood vinegar acts as a powerful natural pest repellent and biostimulant.
  • Increases soil cation exchange capacity (CEC) significantly.
  • Provides long-term carbon persistence (>100 years in soil).
Climate Benefits

Why Choose CLIMATAG Retort Technology?

  • Virtually smoke-free operation via secondary syngas combustion.
  • Maximizes biomass value through multi-product harvesting (Biochar + Vinegar).
  • Ideal for high-integrity carbon credit generation programs.
  • Sturdy engineering for intensive commercial and community operations.
Market Benchmarks

Retort vs Traditional Pyrolysis

Feature CLIMATAG Retort Kiln (BASIC/ECO) Open Pit / Kon-Tiki Kiln Traditional Direct Kilns
Pyrolysis Mode Indirect / Closed Chamber Direct Flame Top-Lit Direct Combustion
Biochar Carbon Purity High (>75% Fixed Carbon) Moderate (50% – 60%) Low (High Ash Content)
Wood Vinegar Recovery Yes (ECO Models) No No
Emissions Level Very Low (Syngas Reburnt) Moderate to High High Smoke Generation
Hot Water Co-Benefit Yes (ECO Models) No No

*Yield and thermal performance depend on biomass moisture content and operational parameters.

Social Impact

Ideal For CSR & Sustainable Agri-Projects

  • Enables rural micro-enterprises to generate multiple revenue streams (Biochar + Vinegar).
  • Perfect fit for Farmer Producer Organizations (FPOs) and Women Self Help Groups.
  • Directly supports climate-resilient agriculture and soil carbon sequestration goals.
  • Turnkey technology deployment for corporate CSR environment and livelihood programs.
