In 1969, Şişecam began to produce soda ash, a primary raw material in the glass industry. Currently, the Company’s soda ash production capacity totals 2.4 million tons/year at its plants operating in Turkey, Bosnia-Herzegovina, and Bulgaria. With this production volume, Şişecam is Europe's fourth and the world's eighth largest producer of soda. Serving as a dependable supplier with high production capacity, top-notch product quality and an expansive marketing network, Şişecam meets Turkey's soda needs while also serving global markets as a major supplier with sales to 80 countries.

Şişecam became a partner of Bulgarian soda ash producer, Sodi which was privatized in 1997, with Solvay (Belgium) and EBRD. After EBRD terminated its partnership, Şişecam boosted its stake to 25% in subsequent years. In 2006, Şişecam acquired Lukavac Soda Plant in Bosnia-Herzegovina and expanded the plant’s production capacity to 585,000 tons/year with significant capital investments.

In 2019, Şişecam entered into a production partnership with an equal shareholding structure to make a natural soda investment with a total production capacity of 2.7 million tons/year in the USA. The entity will use the solution mining method in the Green River region of the US state of Wyoming. Investment activities have been initiated; the plant is planned to be commissioned in 2024. Şişecam holds a strong position in the soda sector and will climb to the top ranks globally upon deployment of its major natural soda investment in the US.

Şişecam’s heavy and light soda, sodium bicarbonate and sodium sulfate production operations primarily target the glass industry, in addition to detergent and chemicals producers, as well as the paper, textiles, food and animal feed sectors. Additionally, Şişecam produces limestone and salt, key raw materials in soda ash production, at its own plants.
