Each retort processed 40 tonnes of oil shale per day and produced an oil yield of 18%. Along with the shale oil extraction plant, an oil shale research laboratory was founded in 1921. Aaloe et al. (2007), p. 21 Following the experimental retorts, the first commercial shale oil plant was put into operation on 24 December 1924. In October 1936, Riigi Põlevkivitööstus was reorganized as the government-owned joint stock company and was renamed Esimene Eesti Põlevkivitööstus.
