Description:
The report gives information on emerging technologies that are considered to be commercially available (Tier 1), currently undergoing research and development (Tier 2), or considered as potentially applicable (Tier 3) for the management of landfill gas (LFG) emissions or for the utilization of methane (CH4) and carbon dioxide (CO2) from LFG. Discussion of emerging technologies is based on information that was readily available as of September 1997. The emerging technologies that are considered to be Tier 1 are: 1) phosphoric acid fuel cells, 2) processes for converting
CH4 from LFG to compressed LFG for vehicle fuel or other fuel uses, and 3) use of LFG as a fuel source for lechate evaporation systems. The Tier 2 technologies covered in the report are: 1) operation of landfills as anaerobic bioreactors, 2) operation of landfills as aerobic bioreactors, 3) production of ethanol from LFG, 4) production of commercial CO2 from LFG, and 5) use of LFG to provide fuel for heat and CO2 enhancement in greenhouses. Tier 3 technologies, considered as potentially applicable for LFG, include Stirling and Organic Rankine Cycle engines. These two technologies could potentially use waste heat from flares used to control landfill gases to generate mechanical energy.
