How does a Rayagada paper mill separate coal boiler CO2 from biogenic CO2?

Count coal and any oil in full in Scope 1. Report CO2 from black liquor, bark and other wood residues as biogenic, outside the Scope 1 total, with their methane and N2O inside it. Add bought electricity at 0.710. Divide by tonnes of paper.

Fossil

• Coal for power boilers, by weight and GCV.
• Fuel oil for lime kilns.
• Purchased electricity.

Biogenic

• Black liquor in the recovery boiler.
• Bark, chips and sludge burnt for steam.
• Lime kiln CO2 from recovered lime mud.

Per tonne

Divide by tonnes of saleable paper and show fossil and biogenic separately for buyers.

What Senseible does here

Senseible reads fuel, electricity and production documents into dated, fingerprinted plant records, so the monthly intensity behind a figure can be traced to its source.

• Black liquor biogenic CO2
• Coal emissions by GCV
• Biomass boiler CH4 and N2O
