Soda Ash is the 10th most consumed inorganic compound in the world, which has been used for over 5,000 years. It is a safe, simple compound and a key component in a variety of industrial processes from the manufacture of glass to dry powder detergents and lithium-ion batteries. It is also an important ingredient in the food and pharmaceutical industries.
Life’s invisible ingredient; Sodium Carbonate, Na2CO3
The ancient Egyptians recovered Soda Ash from dry dessert lake beds or produced it by burning marine plants with high sodium content to produce ashes, which gave the commonly used name of ‘Soda Ash’. They used it to reduce the melting point of silica sand to produce glass vessels and ornaments – the same basic production technique used in glass manufacturing today. The Romans also used its related compound, Sodium Bicarbonate, for medicinal purposes and to make bread.
Successive generations produced Soda Ash in this way until the mid-1800s, when synthetic production techniques were first developed, to supply the increasing demand from an industrialising world.
Today, Soda Ash (Sodium Carbonate) is produced by two main methods, both of which produce chemically identical Soda Ash.
As of 2021, global production of Soda Ash is estimated to reach 62.2 million mt per year.
We use this at both our Eti and Kazan facilities. This patented production method injects heated water into the underground ore body, which then dissolves the trona forming brine solution. The brine is then brought to the surface, and pumped to a central processing facility.
This closed loop system is safer (no underground operatives), has minimal impact on the surface, uses significantly less energy and water than other production methods and also produces significantly less CO2 emissions.
Trona has been found in lake brines or naturally occurring mineral deposits. Trona (a mix of water, sodium bicarbonate, sodium carbonate and sometimes sodium chloride or salt) is the most common and richest source of naturally occurring Soda Ash.
While Trona occurs naturally in a few locations worldwide, the largest and purest deposits are found near Green River, Wyoming, USA and near Ankara, Turkey.
We are proud to supply the world with high quality natural Soda Ash, manufactured in an environmentally sustainable way, which has earned us green product certification.
