History
Origins
Edoardo Guida Garrone founded Erg in 1938 as a company active in the refining of petroleum and tar. The company, which became a refinery after World War II, chose as its trademark a die (from “Dado,” an affectionate diminutive of Edoardo) whose faces bore a three-letter acronym, the initials of Edoardo Raffinerie Garrone, or Erg.
Postwar period
In 1947, production began at the Genoa San Quirico Refinery. Immediately after World War II, in a country in need of reconstruction, energy needs made oil a key energy source. Thanks to the favorable economic situation and the optimal geographical location of the plants, Erg's business experienced rapid development.
In 1956, Erg signed an agreement to refine oil on behalf of BP, which subsequently held a minority interest in Erg's share capital for several years.
