How much electricity and CO2 does a Kishangarh marble processing unit use per square metre?
Divide monthly kWh by square metres of finished slab or tile, then multiply by 0.710 kg CO2 per kWh. A unit using 50,000 kWh to finish 20,000 square metres runs at 2.5 kWh and about 1.8 kg CO2 per square metre. Gangsaws and polishing lines take most of it.
Where the units go
- Gangsaws and block cutters.
- Polishing and calibrating lines.
- Water pumping and recycling.
Add if relevant
Diesel for generators and loaders, and quarry or transport emissions if a buyer asks for cradle to gate.
Example: one month
- 50,000 kWh ÷ 20,000 sq m = 2.5 kWh per sq m
- 2.5 × 0.710 = 1.78 kg CO2 per sq m
