Key Features

Designed For Smallholders & Rural Entrepreneurs

Why Adopt the CLIMATAG Kiln?

  • Low-cost solution (approx. ₹10,000/- including drum, vents, and fittings).
  • Portable and lightweight design (~18–22 kg) for easy field transport.
  • Low smoke generation via controlled top-lit updraft pyrolysis.
  • Short operational duration of 1.5 to 3 hours per batch.
  • Durable and simple mild-steel construction.
  • Ideal for small and marginal farmers, FPOs, and rural micro-entrepreneurs.
Biochar production from agricultural crop residue
Operation Process

How It Works

Controlled heat. Clean biochar. Healthy soil.

1

Fill Biomass

Fill with dry crop residues (cotton/maize/pigeonpea stalks, castor, shell, etc.).

2

Ignite from Top

Ignite top biomass layer to create a flame front that moves downward.

3

Controlled Pyrolysis

Pyrolyze biomass under limited oxygen using airflow bottom holes and vent pipe.

4

Cool & Collect

Cool down unit safely and collect high-grade biochar for soil application.

Efficiency Data

Biomass to Biochar Conversion (Typical)

Practical Estimate: 3 kg Dry Biomass → ~1 kg Biochar

Dry Biomass Input (per batch) Biochar Output (approx.) Yield (%) Biomass : Biochar Ratio
20 kg 6 – 7 kg 30 – 35% ~3 : 1
50 kg 15 – 18 kg 30 – 35% ~3 : 1
100 kg 30 – 35 kg 30 – 35% ~3 : 1
Agronomic Impact

Performance Highlights for Soil

  • Significantly raises soil organic carbon levels.
  • Enhances water retention capacity during drought/dry spells.
  • Improves fertilizer and nutrient use efficiency (NUE).
  • Reduces soil bulk density by ~13%, improving aeration.
  • Supports beneficial soil microbes and mycorrhizal networks.
Climate Benefits

Why Choose CLIMATAG?

  • Converts farm waste into high-value biochar instead of open burning.
  • Enhances overall soil fertility and crop productivity.
  • Helps in carbon sequestration and directly reduces air pollution.
  • Low capital investment with high long-term impact for small farmers.
