In the construction sector, any stone that cannot be used in decoration is called rubble. Rubble is a broken stone, of irregular size, shape and texture.
As an effective material for boosting strength and durability, rubble is especially used for filling-in walls and concrete production. It is also used in the chemicals, cosmetics and paper production sectors.
Iran extracted over 98.67 million tons of rubble in the last fiscal year (ended March 19, 2020).
The country’s potential rubble reserves are estimated at around 12.5 billion tons.
About 21,000 people are directly involved in the rubble stone sector.
Estimates show 59 industrial sectors can use rubble as their raw materials.
With more than 4 billion tons, Iran has the fourth largest stone reserves in the world.
According to Vice Chairman of Iran Stone Association Malek Rahmati, construction stone production capacity amounts to 30 million tons per year.
Iran is among the top five producers of construction stones in the world.
