Invited Session: Energy Recovery
Conversion of LFG and Biogas to Drop-in Diesel

The agricultural and landfill industries make up 29 percent of the U.S. methane emissions. Methane is considered a greenhouse gas that contributes significantly to global warming/climate change. Additionally, these two industries are heavy consumers of fossil fuels and in the U.S. alone, consumed 4.2 billion gallons of diesel fuel annually making up 6.9 percent of the total U.S. diesel consumption. None of the commercial scale waste-to-energy technologies use the CO2 portion of the biogas and simply allow the CO2 to either pass through or be separated from the CH4 and emitted to the atmosphere. This presentation introduces a new catalytic technology (TRIFTS) capable of utilizing both the CO2 and CH4 portions of biogas and incorporates them into the hydrocarbon backbone of the final product of the process (diesel). This renewable source of diesel resembles its petroleum counterpart both physically and chemically and can be used in current day engines with no engine modifications necessary. The heavy equipment and waste hauling trucks can therefore unload and refuel at the same landfill site with a renewable diesel fuel derived from the very waste they hauled. Thus a closed loop process is created from feedstock to end point user.
By attending this presentation, participants will better be able to evaluate new technology developments in the waste-to-energy sector. Participants will gain a better understanding of what future waste-to-energy projects are capable of and how they compare to current waste-to-energy technologies.
