As one of the oldest building materials, people's knowledge and use of natural marble and granite can even be traced back to the beginning of the entire human history. So far, natural granite marble stone is still the best choice for high-end construction and high-end decoration. Certain superior marble and stone varieties can even become synonymous with precious and rare construction materials.
Experts believe that natural marble granite countertops has its own advantages in terms of natural source, recyclability, durability, safety, low (or zero) half-life, non-toxicity, chemical inertness, health and hygiene.
For the marble granite quartz industry, the following characteristics are worthy of repeated consideration. First, natural marble and granite can be recycled and reused all the time. After each use cycle, it can be used as a new raw material to enter other production cycles, and then enter other life cycles through appropriate technology. This infinite recycling and reusable characteristic is unmatched by other building materials; secondly, the strong durability of stone means less maintenance, repair and replacement, which means lower life cycle costs. In other words, the life span of stone can be longer than that of the building where the stone is located, which makes it a great advantage in economic considerations. The German Natural Stone Association initiated a "sustainability study-life cycle assessment of floor covering materials" in 2019. The results of the study proved to be compatible with large-scale ceramic tiles, carpets, PVC, laminates and solid wood floors. In comparison, natural stone floor slabs have a significantly superior life cycle in production, implementation and daily use.
In 2012, the German Natural Stone Association used the Frankfurt Grand Theater Tower, which was awarded the LEED Gold Award by the U.S. Green Building Council, as a model, and carried out a study to evaluate natural stone and glass curtain walls in terms of environmental protection, ecological and economic benefits. The annual energy consumption per square meter of traditional natural stone curtain walls is about 100-150kWh/m2a, while the basic energy consumption of glass curtain wall buildings without insulation at the end of the last century is 300-700kWh/m2a. This is due to the low thermal conductivity of natural stone curtain walls, so the heat consumption of buildings using natural stone curtain walls is very low. From the perspective of the entire life cycle, the damage to the ecology caused by natural stone curtain walls is much lower than that of the equivalent glass curtain wall. In addition, the results of a 2019 study by the German Natural Stone Association (the "sustainability study-life cycle assessment of floor covering materials" mentioned above) showed that the greenhouse effect of carpets can reach more than 20 times that of natural stone. , The global warming potential value of large-scale ceramic tiles in the ecological life cycle is about 84% higher than that of natural stone.
For users, natural marble and granite has another characteristic that is very fascinating. That is, natural marble and granite will not burn, nor will it release steam, gas, smoke, smoke, dust, and fine particles. It rarely contains, forms or releases microorganisms and pathogens. The radioactivity shown in research is often lower than sand, cement, and concrete. And other structural materials, which makes natural marble and granite very much in line with the current needs of health and hygiene. What's more, more importantly, the cost of building, maintaining, and cleaning natural stone curtain walls is much lower than the cost of building glass curtain walls.
