Our Belgian bluestone is one of the most sustainable materials with minimal CO2 impact. This ancient stone, formed over millions of years, is quarried locally, minimizing transportation distances and therefore environmental impact.
For processing, too, we consciously choose to minimize our ecological impact at the Aarschot production site.
We produce 65% of our energy needs with our impressive solar array on the roof of our shed in Aarschot.
This park is among the largest solar installations in the region and underscores our commitment to renewable energy and environmentally friendly production.
Renier collects rainwater separately as much as possible and buffers it for reuse, virtually eliminating our use of city water. All process water is discharged separately to our settling basin, where it is treated by sedimentation.
Then the water is pure enough to be reused in our production process.
This eliminates the need to discharge process water and significantly reduces our use of groundwater.
All surplus natural stone is stockpiled and crushed separately for recycling in water or road construction.
So they are never deposited.

The limestone dust that has sunk to the bottom of the settling basin is further dewatered in a filter press and collected separately.
The sludge is then used as a soil conditioner in agriculture. Thus, the sludge is also never landfilled.
