Since the Industrial Revolution, human has vigorously developed industry and technology. Although life is much more convenient than before, people’s living standards have also improved a lot, but the homeland that human depends on for survival has also been considerably destroyed. Global warming is already a very thorny issue. This is all due to the burning of fossil fuels, such as oil, coal, etc., or the deforestation and burning of them. If we do not have the awareness of protecting the environment, sea levels will rise and humanity will face devastating disasters. Fortunately, many countries have now begun to reduce carbon emissions, both in life and in industry, hoping to take practical actions to protect the environment.

In building construction, environmentally-friendly decorative materials and building materials should also be used as much as possible. For example, mineral wool boards, rock wool boards, and fiberglass boards are also widely used in engineering construction and interior decoration. They can not only help improve the environment, but also meet the requirement of construction. Taking mineral wool board as a sample, the raw material is slag wool, slag wool is using industrial waste slag (blast furnace slag, copper slag, aluminum slag, etc.) as the main raw material, the cotton filamentous inorganic fiber is made by melting, using high-speed centrifugal method or injection method and other processes. In addition, used mineral wool board can be recycled to be new products. In terms of raw materials, it is not only environmentally friendly, but also a very good sound-absorbing ceiling, which is mainly used for decoration in offices and other places. So when we choose decoration materials, we should also choose these environmentally friendly products.
