Landfill Generated Methane Gas

Our building project is a methane pumping facility located at landfill that is the source of the methane. Most of the methane generated by the landfill will be "cleaned up" and pumped to another facility for power generation. Additionally, during the methane "cleaning" process (prior to pumping)there will be waste methane that will be used as fuel for the HVAC units in the methane pumping facility instead of piping in natural gas from the local utility. Is this project a candidate for the On-Site Renewable Energy credit? A second question: Considering that we are capturing a "waste" product (waste methane) and reusing it, can the "waste" methane be regarded as a material and be considered for the Material Reuse credit?
