Emerging Technologies for the Management and Utilization of Landfill Gas
Roe, S.; J. Reisman; R. Strait; M. Doorn, Pechan (E.H.) and Associates, Inc., Rancho Cordova, CA.
Report No: EPA 600-R-98-021, 78 pp, Feb 1998

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. The emerging technologies that are considered to be Tier 1 are phosphoric acid fuel cells, processes for converting CH4 from LFG to compressed LFG for vehicle fuel or other fuel uses, and use of LFG as a fuel source for leachate evaporation systems. The Tier 2 technologies covered in the report are (1) operation of landfills as anaerobic bioreactors, (2) operation of landfills are 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.

Guidance Note on Recuperation of Landfill Gas from Municipal Solid Waste Landfills
Johannessen, Lars Mikkel.
The World Bank, Washington, DC. Urban & Local Government Working Paper Series No. 4, 29 pp, Sep 1999

This note helps guide task team leaders and members to prepare projects involving the landfilling of municipal solid waste, landfill gas (LFG) recovery, and introduces the option of an enhanced bioreactor landfill. Guidelines of conducting a baseline feasibility study are included in this note, along with an overview of the construction, operation, and training requirements for the implementation of LFG recovery. Costs and benefits of LFG recovery are illustrated together with a comparison of the economics of LFG recovery from a traditional landfill and from an enhanced bioreactor landfill.
