[Digestion] compressing biogas

[Michael Smith]

 What a GREAT discussion. If someone will, please respond to my scenario.
   A 10 acre plot with a home and one or more greenhouses....10x100 feet or so. I will have access to grass clippings from commercial and multi-family area contractors 5 days a week for 8-9 months of the year. Irrigation from all is from well water and the fertilizer is the available commercial brands used in the Midwest. I would like to digest this for the fertilizer affluent and solid matter most of all. I also would like to compress the gas for intermittent use for electrical, water heating, or heating for the greenhouses. If feasible to power a vehicle, it would be nice to have the option of driving to market, to the store, or social events in a bio vehicle. 
  Power for the homestead is wind, battery backup and generator backup as well. 
I'm sure there are others in the U.S. with the same idea. However, the standard answer is to use it at the time it is made. Is there an economical way for this scenario to come alive?
 By the way, orchard waste, as well as garden wastes would contribute also. All this organic material is FREE. In fact, it is savings to the contractors to give it to me instead of paying to dump it in a landfill.
