Work in progress
The Domain & Royal Museum of Mariemont is currently undergoing major conversion work to replace all the windows in the museum's main building.

Conversion work
Funded by the European Union as part of the Recovery and Resilience Plan (RRP), this project represents a great opportunity for the museum, which will be celebrating the 50th anniversary of the building designed by architect Roger Bastin in 1975.
This vast project meets several key challenges: improving thermal insulation, reducing energy consumption and improving the safety of the building.
In this way, it is part of a process of ecological transition, while also contributing to greater comfort for visitors and staff.
The work is being carried out by the Infrastructure Department of the Wallonia-Brussels Federation, in close collaboration with the museum's teams. Groven+ will be carrying out the work, which will take several months to complete.

Recycling glass
Recycle Glass is AGC's service of collecting flat glass wastes from industrial losses and from deconstruction projects (end of life glazing from commercial projects or residential buildings) to be recycled and remelted in new, more sustainable, flat glass production.
Using cullet reduces direct and indirect CO² emissions. Cullet requires less energy to melt and replaces virgin raw materials that emit CO² during extraction, production & melting.
1 ton of cullet = Up to 0.7 tons of CO² saved
