A study, carried out by The University of Manchester, assessed the potential cradle-to-grave environmental benefits of refurbishing elevator drives as a circular economy strategy, contrasting with the conventional practice of replacing with a new drive unit.

The study shows that refurbished drives have the potential to reduce the total amount of waste produced by 91-92%. It was also observed that the reduction in material usage achievable via refurbishment enables a decrease in the drive’s environmental impacts of 53-91% compared to the production of a new drive.
