According to "Trends of development of national economy of the USSR for 1959 - 1969", Council of Ministers of the USSR approved for the next seven years the list of the largest constructions of the country where Belarus fertilizer factory (ÀÒZ) was included. In October 1960 the building of temporary auxiliary structures was begun, and in a year - the management of the factory under construction was formed. Initially, it was foreseen to create the production of ammonia (capacity 167 thousand tons a year), weak nitric acid (240 thousand tons), urea (70 thousand tons) and ammonium nitrate (313 thousand tons). In January 1965 the first lines of plants Ammonia-1 and Urea-1 were put into operation, and in two years (in January 1967) the second line of plant Ammonia-1was also put into operation. The second stage of development of the enterprise included the construction of the second stage of ammonia production (March 1970), urea (June 1971) and caprolactam-1 production (April 1970). In October 1970 Grodno fertilizer factory was transformed to Grodno chemical complex named after S.O.Pritytsky, and in May 1975 chemical complex was transformed to Grodno production association "Azot" named after S.O.Pritytsky. The third stage of development is connected with the construction of high-capacity. plants for ammonia production (May 1979) and urea (October 1979) in greater degree supplied with modern computerised equipment, than constructed before productions.
In June 1986 plant Urea-4 with capacity of 330 thousand tons a year was put in operation. In July 1992 instead of the production of prilled urea was started the production of urea solution used for manufacture of liquid nitrogen based fertilizers (UAN). In December 1993 instead of ammonium nitrate production the production of UAN was started. In August 1994 the production of crystalline hydroxyl ammonium sulphate was adjusted. In July 1996 on the basis of the ammonia-2 plant was organized the production of methanol-raw. In December 1998 according to a government program of import substitution methanol- raw plant was reoriented to methanol-rectificate production with the capacity of 45000 tons a year. In August 2000 Grodno production association "Azot" was transformed to Grodno industrial republican unitary enterprise "GPO Azot" and in two years - to joint-stock company "Grodno Azot". Since October 2007 the enterprise manufactures mixed fuel bio diesel with the 5 percent contents of bio fuel manufactured here - methyl ethers of fat acids of rapeseed oil. In June 2008 the installation for production of carbonic acid of the first-rate quality with capacity 24 thousand tons a year was put into operation. In November 2008 gas turbine power station with the capacity 16 ÌW was started up and since September 2009 the second similar gas turbine power station is in operation.
