[Digestion] Bio-gas from unused fruits and vegetables and waste

[Art Krenzel]

Michael,

Constructing a high capital cost Anaerobic Digestion (AD) system with only a 
single, seasonal feedstock is not good planning.  A well designed AD system 
needs year round feedstocks to maximize production and economic return. 
Though it is a crime against nature to waste fruit dropped by trees, they 
represent only a fraction of the feedstocks needed to operate a year round 
AD system.

Fruits are better feedstocks for a fermentation process due to high sugar 
contents (beer, alcohol, etc) however will work in AD (methane) as well.
