How do I work out CO2 per tonne of soybean meal at a solvent extraction plant in Indore?

Add boiler fuel CO2 and electricity, then divide by tonnes of seed processed or meal produced. Steam for the desolventiser-toaster and hexane recovery is the largest share. Rice husk or soya husk fuel counts as biogenic, reported separately, with only its methane and nitrous oxide in Scope 1.

Steps

1. Boiler fuel by type and quantity per month.
2. Fossil fuel × its factor; biomass fuel reported as biogenic.
3. Electricity kWh × 0.710.
4. Divide by meal or seed tonnes, and say which.

Hexane

Hexane lost to air is a solvent loss, not combustion. Track it for cost and safety; it is not usually counted as CO2.

What Senseible does here

Senseible reads fuel invoices into a dated, fingerprinted record, so each figure shows the quantity, factor and document it came from.

• CO2 per tonne of steam
• Biomass in a boiler
