Our history

The history of the enterprise dates back to 1920, when the “NITRAT” Joint Stock Company was established Its purpose was to manufacture chemical and military products. The company’s headquarters was initially in Warsaw, until the construction of a manuacturing plant in Niewiadów in 1924 was completed. Construction works, delivery of technological lines, assembly of machinery and equipment was fell to Italian specialists. In addition to TNT, artificial fertilizer was also produced in Niewiadów.

During World War II, the company was destroyed, the remaining part was taken over by the Occupant. After the liberation, the plant remained under the control of the Pabianicka Spółka Akcyjna Przemysłu Chemicznego „CIBA” (“CIBA” Pabianice Chemical Industry Joint Stock Company), and then the Zjednoczone Zakłady Przemysłu Barwników „BORUTA” (“BORUTA” United Dye Industry Plant) in Zgierz.
