Finally a good use for Brussel sprouts and asparagus.
It is amazing how much food we waste. It would be interesting to see the full analysis of the digester operation vs simply diverting the food waste to a compost program instead of sending it to the landfill.
And you would do what with 150 tons a day of compost?
i know of a few biogas power plants in Europe that take in the waste food from prisons, schools and large office complexes, digest it for gas to burn for steam power then sell the compost back to the local farmers. Our energy might still be a bit too inexpensive for that to work here, but if you look at something like Deer Island in MA, where they process the human waste and sell the compost back, it at least creates multiple cash streams. Baby steps. I know biogas digesters, little tiny ones, are taking off in third world countries...saves the remaining trees and provides cooking gas for pretty cheap infrastructure.
