GÜTERSLOH, Germany—Appliance manufacturer Miele has announced that all of the aluminum needed to make its ovens will be produced exclusively using green electricity from hydropower. Miele anticipates that the move will reduce its CO2 footprint by 645 tons per year.

Miele had already been sourcing low-CO2 steel for its appliances since 2021. 

“We are the first in our branch of industry to prove that CO2-reduced aluminum can be successfully used in ovens and help reduce the CO2 footprint,” says Hans Krug, senior vice president for procurement at Miele. “The objective is to use climate-friendly aluminum on a broad front and thereby contribute towards a future-proof economy.”

In a first stage, Miele will order around 150 tons of CO2-reduced aluminum this year for the production of trim. The aluminum is converted into an alloy at the supplier’s foundry, further processed and then supplied to Miele in the form of finished components. The aluminum is poured on lines that use regenerative burners, which utilize waste heat from the production process. 

As an added environmental benefit, all of the aluminum used in Miele’s appliances is recyclable.
