Viru Keemia Grupp （VKG） is an Estonian holding group of oil shale industry, power generation, and public utility companies.
Esimene Eesti Põlevkivitööstus After Estonia gained independence, the state owned oil shale enterprise, Riigi Põlevkivitööstus （English: Estonian State Oil Shale Industry）,
was established as a department of the Ministry for Trade and Industry on 24 November 1918.
Shale oil production started in Estonia in 1921 when Riigi Põlevkivitööstus built 14 experimental oil shale processing retorts in Kohtla-Järve.
These vertical retorts used the method developed by Julius Pintsch AG that would later evolve into the current Kiviter processing technology.
Along with the shale oil extraction plant, an oil shale research laboratory was founded in 1921.
Following the experimental retorts, the first commercial shale oil plant was put into operation on 24 December 1924.
This is considered as a beginning of the history of Viru Keemia Grupp.
In October 1936, Riigi Põlevkivitööstus was reorganized as the government-owned joint stock company and was renamed Esimene Eesti Põlevkivitööstus.
It operated three shale oil extraction plants and was constructing the fourth plant.

In 1948, the company opened an oil shale gas plant, and for several decades the oil shale gas was used as...
