[GreenYes] Landfill methane recovery data

Does anyone have recent data or studies relating to the capture rate of
methane from landfills? As we expand our food scrap diversion programs we
have received criticism that we are stealing fuel from a co-generation
facility at our regional landfill. I realize that in dry tomb landfills, any
reduction of methane from removing food scraps is negligible due to the
rapid decomposition of food scraps. This has been answered by critics who
state that the latest landfill and methane recovery technology does capture
methane from food scraps and all of the methane generated by a landfill. I
have read one study that states: despite claims of 70-75% recovery rates,
the actual amount being recovered is more like 20%. Can anyone direct me to
additional information to back up this data?
