Some of the larger dairy farms in VT are doing just that, with seed money from the state.
They use the methane to run generators for power and when the process is complete they recycle the bedding for another $50/$60 K savings per year.
It costs about half a million to set the system, up on a farm with sufficient livestock to make it practical.
