Maximizing Value from LFG
� Keep the number of parties to a minimum
� Choose an ownership structure that maximizes tax credits and other incentives to the project, then select a gas pricing schedule that shares these values
� Define gas quality specifications and responsibilities with priority to landfill compliance
� Share any potential market upside, once the return on capital by the investing party is achieved
Goal is to achieve both parties’ interests in promoting green energy and meeting
compliance, while sharing in financial returns

Challenges
� More strict emissions limits require more sophisticated prime movers
>> increased maintenance, gas clean-up
� Higher costs and sophistication of electrical interconnects
� Increasing standards for pipeline quality gas
� Gas clean-up: H2S, siloxane
� Increasing capital costs

Landfills as a resource
� Enthusiastically support and promote “reduce, reuse, and recycle”
� Recognize that landfills are an environmentally sound part of the solution for a community’s management of its solid waste
� Promote landfills as an energy resource
