Four Rivers announces entitlement to Renewable Obligation Certificates

Four Rivers BioEnergy Inc. (OTCQB:FRBE), which is developing a waste to energy plant in North East England under the trade name ‘Verta Energy’,  today issued a letter to shareholders from its Chief Executive Officer, Stephen Padgett, updating them on various matters relating to progress at its Verta plant.

In his letter Mr. Padgett announces that the UK energy regulator (OFGEM) has completed its analysis of the feedstock which Verta produces in its waste oil processing plant and which it will use to generate electricity and has confirmed that it constitutes ‘100% Biomass’.  Once Verta has installed OFGEM approved meters, it will be formally accredited to receive Renewable Obligation Certificates on the electricity that it generates.

In his letter Mr. Padgett states “This is clearly excellent news, since it underpins the theoretical operational profitability of the proposed plant”.

The entire letter has been posted to the Company's web-site (http://www.riv4ers.com) under the Shareholder Letters section
