When a Gujarat chemical unit sends hazardous waste to a common incinerator, how is that counted?
It is Scope 3, Category 5, waste generated in operations, not your Scope 1. Multiply the tonnes on each manifest by a factor for incinerated waste, ideally from the facility's own fuel and waste records. If none is given, use a stated estimate and mark it as one.
Why not Scope 1
The incinerator is owned and run by someone else. Your Scope 1 covers only fuel and process emissions in equipment you control.
What to ask the facility
- Support fuel used per tonne of waste.
- The share of fossil carbon in the waste it receives.
- Whether it recovers energy, and how it reports that.
Records
Keep the manifests and the facility's invoices by month. They give tonnes, waste category and date, which is what an auditor checks.
What Senseible does here
Senseible reads fuel, steam, electricity and raw material invoices into a dated, fingerprinted record per unit, so a product figure can be traced back to the documents behind it.
