A 100% environmentally sustainable choice 

Our Belgian bluestone is one of the most durable materials on earth. Formed over millions of years, this ancient stone is extracted locally in an environmentally friendly manner. Combined with limited transportation distances, this significantly reduces the ecological footprint.

For processing, too, we consciously choose to minimize our ecological impact at the Aarschot production site:

One of Aarschot's largest solar parks

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.

Water Treatment

Rainwater collection and use

Renier collects rainwater completely separately 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.

Surplus natural stone to road construction

All surplus natural stone is stockpiled and crushed separately for recycling in water or road construction.

So they are never deposited.

Waste

Sludge to agriculture

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.
