Title: How much energy does it take to produce washing powder?
Post by: Petrochemicals on 01/02/2022 16:49:25

A certain manufacturer of biological laundry powder makes a claim about washing at a colder temperature is greener for the environment as it utilises less energy, less energy meaning less co2 emissions. Knowing that chemically potent things such as fertiliser is energy intensive to produce, what sort of energy input is required for laundry detergents?

Incase anyone wondered,

440g embodied carbon in the appliance per wash
600g to 900g embedded carbon in the washing powder

And energy for the cycles

'0.6 kg CO2e washed at 30°C, dried on the line
0.7 kg CO2e washed at 40°C, dried on the line
2.4 kg CO2e washed at 40°C, tumble-dried in a vented dryer
3.3 kg CO2e washed at 60°C, dried in a combined washer-dryer'
