Considering the production capacity of ceramic tiles in the country and the capacity of the provinces of about 300 million square meters per year, about 3 million and 900 thousand cubic meters of water evaporates and is wasted annually, which is equivalent to the consumption of a city of 200 thousand people. Also, the water consumed is not recovered in any way, and if this issue is taken into account, the above population will increase 1.5 times.
The dryness of the country, due to the amount of desert areas and annual rainfall and the reduction of water reserves, is one of the largest water-consuming industries in the ceramic industry. On average, about 15 liters of water are required to produce each square meter of ceramic tiles, of which about 13 liters of water evaporates through the spray and is removed from the spray depending on the weight of the tile.
Basically, in all countries, the type of industries and production methods are based on the climatic conditions of that country. For example, Brazil produces one billion square meters of ceramic tiles, and due to the high cost of energy, 95 percent of this production is produced through dry powder; In Iran, due to the problem of water shortage, one of the best methods for producing tiles and ceramics is to use the dry powder method, which requires further investigation and studies on this method, as well as new mines and other related matters.
