What are the emissions of bleaching cotton fabric per metre?
Bleaching uses hydrogen peroxide and other chemicals, which are Scope 3 purchases, and steam to heat the bath, which is boiler fuel in Scope 1. Add washing water heating and machine electricity, then divide by metres or kg processed.
Per metre
- Hydrogen peroxide and auxiliaries, by kg.
- Steam per batch, converted to boiler fuel.
- Electricity at 0.710 kg CO2 per kWh.
Combine steps
Combined scouring and bleaching in one bath can save steam; measure before and after.
What Senseible does here
Senseible reads the energy invoices behind the making stage into a fingerprinted Scope 1 and 2 record, and keeps material invoices on the Scope 3 trail. Material factors come from your supplier or a named database and are labelled with their source, so the product figure can be traced line by line.
