Two waste products, nitrate-rich sewage wastewater and power plant CO2 emissions, are combined and converted into a renewable, biomass energy source, which supplies the fuel to the power plant. The power plant, wastewater treatment facility, and biomass growth unit are preferably located on one site and arranged for convenient transfer of the CO2 and wastewater to the biomass growth unit; harvesting, processing and return of biomass from the growth unit as fuel to the power plant; and discharge of the de-nitrated wastewater into the same body of water used as the heat sink by the power plant, e.g., a lake, river, or sound. The present invention thus provides an integrated approach to minimization of CO2 emissions and nitrate discharge while achieving improved efficiency in the generation and harvesting of the biomass.
