The Management Board of Trzebinia Refinery has decided to restart the production and sale of ON BIO diesel fuel, a blend containing 20% FAME esters

The Management Board of Polski Koncern Naftowy ORLEN S.A. (“PKN ORLEN”) hereby informs that on 16 July 2007 the Management Board of Rafineria Trzebinia S.A. (“Trzebinia Refinery”) has decided to restart the production of ON BIO diesel fuel, a blend containing 20% FAME esters (fatty acid methyl ester - FAME). The decision to restart production was preceded by a detailed economic analysis made by Trzebinia Refinery, which referred to the changes introduced by the “Regulation dated 11 May 2007 regarding changes to the excise tax and changes to some other regulations” (“Regulation dated 11 May 2007“) to the earlier “Regulation regarding bio-components and liquid bio-fuels”. The Regulation dated 11 May 2007 increased the excise tax concession by approximately PLN 0.05 per litre of bio-components in diesel fuel, and decreased the excise tax from PLN 0.20 to PLN 0.01 per litre for pure bio-components fuels for combustion engines.

Moreover, the Management Board of Trzebinia Refinery decided to restart the sale of diesel containing 20% FAME bio-components on 16 June 2007. At the end of 2006 Trzebinia Refinery had been selling diesel containing 20% bio-components under the name “ON BIO 10”. In order to provide more precise information about the share of bio-components in diesel, Trzebinia Refinery has decided that the product will now be named “ON BIO 20”.

PKN ORLEN holds 77.2% of the shares in the Trzebinia Refinery Capital Group.
