How We Cut Waste (Not Corners)
How stoneCIRCLE reduces our waste and water use without compromising quality
Natural stone lasts for generations. Our job is to fabricate it with the lightest touch. At stoneCIRCLE, sustainability isn’t a badge; it starts with our factory, built to BREEAM standards, and with the decisions we make every day on the factory floor.
We start with CNC nesting to plan cuts that minimise offcuts. What remains is never ignored: usable pieces are catalogued for future use; the rest is collected and crushed for construction, keeping stone out of landfill and reducing haulage. When we built our extension, we used our recycled waste as hardcore in the foundations.
CNC nesting: optimising slab usage while reducing wastage.
Water matters. Cutting and polishing are water-intensive, so our factory runs a closed-loop system that recycles both rainwater and process water. This step makes us almost self-sufficient in water, maintaining machine performance while reducing mains consumption.
Hand polishing requires a water wall to capture dust.
Energy savings are addressed with 100 m² of on-site solar panels, supporting the precision work of our CNC machines. But technology isn’t the whole story. Final finishing and quality control are always done by hand. Our masons correct, refine and sign off every edge and surface. That human judgment increases longevity; less rework, fewer replacements, and better projects over time.

From a single stone block, a stone plinth is made lighter by hollowing its inner part.
Work in progress: our CNC machine carves cylindrical holes inside the solid stone plinth.
Offcuts become construction aggregate—nothing wasted.
This union of state-of-the-art machinery and experienced craftsmanship is why our clients trust us with complex briefs. Sustainability is not a compromise; it’s how we reach the standard we’re known for.
CNC machines optimise each cut.
