Minnesota Biofuels Emission Factor Report

The results of the study provided emission factors for CO, NOx, PM, SO 2, and VOC for all the priority biofuels at stationary combustion sources. Most of the reported emission factors were for co-firing applications of the priority biofuel and fossil fuels. Emission factors for air toxics were limited to HCl from wheat straw and PAH's

Characterizing Emissions from the Combustion of Biofuels

PM emissions were highest for the No. 2 fuel oil, at 18 mg/dscm. Most of the PM mass for the No. 2 fuel oil was in the condensed phase. The two biodiesel fuels each had total PM mass emission concentrations between 3 and 4 mg/dscm, with the majority of that (approximately 2.5 mg/dscm) in the filterable fraction.

5 Environmental Effects and Tradeoffs of Biofuels ...

The quantity of these emissions depends on various factors, including combustion technologies, emission controls, temperature, and the level at which biofuels are blended into petroleum-based fuels. Reviews of the literature have revealed that relative to petroleum-based fuels, the use of biofuels tends to decrease emissions of some pollutants while increasing those of others.

For Gas biomass, the CEF is based on the assumption that 50% of the carbon in the biomass is converted to methane and 50% is emitted as CO2. The CO2 emissions from biogas should not be included in national inventories. If biogas is released and not combusted 50% of the carbon content should be included as methane.
