Burgundy limestone and the environment
Today people are becoming increasingly aware that everything we buy has an effect on the environment. When building or restoring a house this is very important as the choices will impact for many years. We know that our Burgundy limestone is amongst the most environmentally friendly materials available. Let’s compare with other hard surfaces:
- Cement products, which are often sold as natural stone, are the source of around 8% of the world’s man-made CO2 emissions.
- Ceramic natural stone imitations use patterns that are sometimes only paper-thin. They need to be fired once or twice at temperatures of 1150 to 1300°c
- Quartz or “engineered” stone uses petroleum-based resins that can emit volatile organic compounds.
- Sintered ‘stone’ needs to be heated to over 1200°c for around 2 hours to imitate natural igneous rocks.
- Quartz stone and sintered stone have a high quartz content which carries a risk of silicosis for producers.
Advantages of using natural stone:
- It is 100% natural and a noble product.
- Stone breathes, offering a healthy environment inside the house. It does not release any toxic emissions into the air.
- Stone has a natural thermal inertia appreciated for under-floor heating for example.
- A natural regulator of temperature, it absorbs heat during cold periods and maintains freshness in summer.
- Burgundy limestone is extracted in the Burgundy quarries respecting current environmental regulations, and worked according to rigorous procedures.
- It does not need any finishing product and develops a natural patina (calcium carbonate) over the course of time. Water is its best friend to conserve its natural beauty.
- With extreme weather events becoming more frequent it will resist damage by floodwater far better than most man made products.
Ever since Les Ateliers Pierre de Bourgogne’s started up 15 years ago our priority has been to respect the environment:
- We source most of our blocks from local quarries within a 30km radius reducing transport distances.
- The stone is extracted in Burgundy quarries respecting the current environmental regulations.
- The majority of the stone deposits are relatively shallow and located on arable land. Before extraction starts the top soil is removed and stored.

- The overburden is stored separately and used to fill the quarry after extraction together with any unusable waste stone from local factories. The top soil is replaced and the land returned to agriculture.
- Our modern factory buildings, with excellent insulation, limit heating requirements and reduce noise emissions.
- Modern machinery has been installed to limit handing and energy requirements and to maximise productivity.
- Off cuts are reprocessed to produce cobbles and hexagon tiles, reducing waste to a minimum.
- The remaining waste is returned as fill to the local quarries.
- Waste water from the cutting machinery is filtered and pressed, producing fine lime powder that is used to restore lime deficient soil for agriculture. The filtered water is recycled to the cutting machines, reducing consumption to 10% of total requirements.
- Natural stone can be recycled for hundreds of years. Stone from Roman Temples was used to build Cathedrals and Chateaux. Today Burgundy limestone reclaimed from old farm buildings is highly prized for new houses.
