Japan is a leading country with a strong environmental protection policy. The government promises zero carbon emissions by 2050. To achieve this, many companies and sectors are encouraged to step up their efforts to use environmentally friendly materials, including construction.
One of these promising materials is volcanic rock that is found in abundance in Japan. And the country is a volcanically active land. Even its natural symbol, Mount Fuji, is actually a volcano. This Tokyo-based company promotes the use of volcanic rock to cover the surface of the walls of buildings, bridges and roadsides.
The idea was initially to create a cosmetic effect for the building to blend more into the surrounding natural landscape, but later moss and plants grew out of the porous surface of the volcanic rock. This unexpected development revealed the potential of volcanic rock to promote vegetation.
“I was born near the beautiful Mount Fuji with a lot of volcanic rocks around and noticed that plants grew more on it in the garden, so I understood that it was because the rock had a small hole that made it a good place for vegetation and plant growth, so I came up with the idea of using such a volcanic rock as an environmentally friendly building material in different forms, ”said a Volcanic Rock Company official. Natural volcanic can be used in different sizes and shapes, even cut into thin concrete plank with encrusted volcanic rock that can be attached to the exterior of an already existing surface.
Another material, which does not contain concrete, is an ultra-thin, ultralight material that can be cut to any size and fixed even to a curved surface of a different shape. “Regarding the CO2 emission, the concrete manufacturing process generates a lot of CO2 emission, but in the case of natural materials like volcanic rock, the process does not include the production of material because we use rock. naturally available so the CO2 emission is very low, “said a Volcanic Rock Company official.
The environmentally friendly characteristic of volcanic rock makes it suitable for reviving the ecosystem of urban areas when used as a building material. (ANI)
