What are the emissions from shot blasting castings?
Shot blasting uses electricity for the blast wheels, dust collector and, in air blasting, a large compressor. Multiply the machine's kWh by 0.710 kg CO2 and divide by tonnes cleaned. Worn shot is bought steel, in Scope 3.
Measure
- kWh from a sub-meter on the blaster.
- Tonnes of castings cleaned.
- Kilograms of steel shot bought.
Cut it
Run full loads, fix compressed air leaks on air blasters, and stop the dust collector between batches.
What Senseible does here
Senseible reads the plant's electricity bills (CEA grid factor 0.710 kg CO2 per kWh, CO2 Baseline Database version 21.0) and fuel invoices (IPCC 2006 defaults) into a fingerprinted Scope 1 and 2 record, the plant-level input to a per-unit figure. Bought-in materials go to the supplier evidence trail; product reports are self-declared drafts.
