IGSAS, the first Potassium Nitrate producer in Turkey!

Potassium Nitrate, a need of Turkish growers that was supplied through importation only, is now produced in IGSAS Kutahya Plant for the first time in Turkey, thanks to a new investment.

With this 40-Million-Euro-worth investment that’s considered as a “Strategic Investment” by the Ministry of Economy, IGSAS positively contributes to the current account deficit in Turkey.

Apart from potassium nitrate, nitric acid production is an investment carried out in IGSAS Kutahya Plant.

By making this investment for the future of Turkish agriculture and industry, IGSAS aims to

  • Contribute to local product variety,
  • Develop projects to support energy efficiency,
  • Minimize imported products and support exportation,
  • Improve product quality
  • Access information and technologies to compete with international companies.
