# Does power from dolochar count in a Raigarh sponge iron unit's emissions?

Canonical: https://senseible.earth/answers/raigarh-sponge-iron-dolochar-power-co2

Yes. Dolochar is the char left after the coal based kiln, and burning it in your boiler releases fossil CO2 from its fixed carbon. Count it in Scope 1 from tonnes burned and a carbon content test. The power it makes then cuts what you buy from the grid.

## Why it is not free

Dolochar is a by product, but its carbon came from coal. Treating it as zero hides real emissions and buyers who audit the kiln balance will spot the gap.

## How to count it

1. Weigh dolochar sent to the boiler each month.
2. Test its fixed carbon, or use a recent lab report.
3. CO2 = tonnes × carbon share × 44/12.
4. Add it to the coal burned in the kiln, without counting the same carbon twice.

## For CBAM

Sponge iron is a CBAM good. Power made from dolochar inside your boundary is part of the direct emissions of the plant, so the kiln and the boiler go into one figure.

## What Senseible does here

Senseible reads fuel, electricity and freight invoices into a dated, fingerprinted record per site, so each figure you send a buyer traces back to the documents behind it.
