Azot (Cherkasy)
Azot, also known as Cherkaskyi Azot after Cherkasy, the location of its chemical plant, is one of the biggest manufacturers of nitrogen fertilizers in Ukraine. Ukrainian oligarch Dmytro Firtash's chemical-industry holding corporation, Ostchem Holding, manages the company as well as several other fertilizer manufacturers in Ukraine and other post-Soviet states. Azot serves both the domestic and export markets. Products are primarily ammonia and ammonium salts, but also include certain specialty ion-exchange resins. The plant's name, Azot, is Ukrainian for "nitrogen." Overview 
The plant began construction in 1962. On March 14, 1965, it released the first batch of liquid ammonia. By 2011, the company controlled 43 subdivisions on  at the southern outskirts of Cherkasy city. These facilities have the capacity to produce up to 3 million tonnes of fertilizers per year, which can then be exported worldwide. Products include:
 weak nitric acid
 granular ammonium nitrate
 ammonia, liquid or aqueous
 prilled urea
 urea-ammonium nitrate solution
 ammonium sulphate, aqueous or crystalline
 caprolactam, crystalline or liquid
 liquefied carbon dioxide, and
 ion-exchange resins, including annionite AV-17-8 and cationite. Effects of the 2022 invasion 
The 2022 Russian invasion of Ukraine restrained export and import (the Black Sea harbours are blocked by the Russian Navy) of raw materials, and finished products. It has also reduced domestic demand for fertilizers, due to a reduction in crop planting. Philanthropy 
The company's ultimate owner, Dmytro Firtash, has developed the "Save Your City " brand for his philanthropic endeavours. The company financed renovation of the "Friendship of Peoples" concert hall and public plaza in downtown Cherkasy. In the surrounding area, it has paid for road repairs and trolleybus transfer center improvements; renovated schools; and manages a children's hospital specializing in neurological disorders.
