Natural Stone an Environmentally-Friendly Choice

Granite, marble, travertine, and other natural stone materials can create a warmer and more inviting atmosphere in a home or office space and serve as an excellent choice of décor, especially for nature lovers. However, environmentally conscious people may wonder whether it leaves a significant carbon footprint.

Natural Stone and Reconstituted Stone

Semantically speaking, it is advisable to distinguish first the natural stone, by opposition to other stony types such as the reconstituted stone, which are not natural. Contrary to reconstituted stones, the natural stone is an ecological material, constituted essentially by natural minerals. It is very recyclable and is, contrary to wood, rot-proof and insensible in the attacks of insects, termites, or rodents.

Stone Is Not a Limited Natural Resource

Stone can be found in almost every country in great abundance. For example, marble has been quarried in Carrera, Italy for centuries, and there is still an abundant supply. In the United States, there are quarries within 500 miles of nearly every major metropolitan area. Quarry techniques have also improved worldwide, and most of the time, explosives are no longer required. It’s a pretty clean industry with zero waste.

Natural Stone is Minimally Processed

There is very little environmental impact in stone fabrication, because fabricators use specially designed wet blades to greatly reduce the amount of silica, or stone dust that is released into the air. Unlike stone, composite materials like wood, brick, ceramic, glass, and concrete require natural resources and energy to create. Many recycled composite materials contain polyester binders, which are basically plastic, and can emit VOCs (volatile organic compounds), because they are solvent based. The lifespan of composite materials is also limited, unlike natural stone, which virtually lasts forever. Polyester resins in engineering materials will break down over time and are sensitive to heat and sunlight, which is why natural stone is the preferred choice for outdoor décor.

Cleaners and Sealers

Environmentally friendly, pH neutral cleaners are recommended over harsh cleaners for natural stone. Nearly all sealers used on natural stone are water-based and FDA approved.

High Durability Means Little or No Waste

Have you ever visited to an old church or historical building where the original granite or marble floors, walls, and other surfaces were still in use and looking untouched by time? Natural stone not only can withstand centuries of traffic and use, but with proper care and regularly scheduled maintenance, it can continually look brand new. When natural stone is damaged, in most cases, it can be completely restored, and if for some reason it is damaged beyond repair, it does not have to end up in a landfill. It can be used for other building materials.

Calcium-based Residual Material from Marble Quarries

According to Hueston, calcium-based residual material from marble quarries is used for vitamins, medicines, and antacids. There is even a North Carolina quarry that uses their waste for local chicken feed.

Stone is Easily Recycled

The great thing about stone is that it came from the earth, and whatever is not recycled can be simply returned back to the earth.

Changing our Behavior

The choice of building materials and decoration has been conditioned by purely economic and technical requirements; only rarely considering their impact on the environment and health. At the time of Sustainable Development, it is self-evident and concepts of ecology, protection of natural resources and CO2 emissions resonate in everyone minds, many of us are changing our behavior as buyers and consumers.
