In Differdange, the dedusting project enters its second phase

A phase 1 exemplary

Launched in December 2023 with the dismantling of the Hayange dust collection unit, this first phase focused on several technical aspects: dismantling and transporting the equipment, civil engineering work, reassembling the system, and integrating the electrical components.

Their main challenge: dismantling, transporting, and reinstalling a machine that was not designed to be moved or upcycled. They successfully met this challenge, in strict compliance with safety regulations, the schedule, and the allocated budget.
By summer 2025, the machine was installed in Differdange and already in working order.

Phase 2 : a connection as close as possible to emission sources

With a fully operational central vacuum system, the team is now focusing its efforts on connecting the main identified emission sources: the new black slag hall, the ladle furnace, and the ladle tumbler, which will be connected before the end of 2025.
The custom-made XXL hoods and ducts arrived on site in July and are currently being installed.
Once these connections are finalized, the entire system will undergo a testing and calibration phase before being officially commissioned. This project will significantly improve air quality in Differdange, benefiting the well-being of our employees, local residents, and all our stakeholders.

This project is fully in line with a responsible approach, from its design, through the reuse of a disused facility located 30km from the site, to its operation, allowing an 80% reduction in diffuse emissions. It also embodies rigorous project management, which is much more complex than installing a new dust collection system, while constantly ensuring that feedback from our employees and stakeholders is incorporated.
