[Gasification] biodigestion- gassificaiton or incineration

[Jan Mowbray]

With respect to the following statement by Kermit Schlansker,Date: Fri, 5 May 2006 09:41:59 -0500

The overwhelming advantage of biodigestion over all other processes is that it is a cold process and preserves nitrogen in the effluent and solids. It also has the advantage that cellulose is the energy source.  I would think that sewage mixed with alfalfa or other hay in serial septic tanks would produce energy, fertilizer, and cleaner effluent Since it takes a lot of energy to produce nitrogen fertilizer this would be a great plus.
Would it therefore follow, that by encouraging use of home in-sink food waste disposers, we would not only have safer, cleaner effluent at the sewage treatment plant, but also a quick, clean, cheap, way to dispose of kitchen organics, with marginal increase of volume to the sewage system, (using an average of 1.5 litres water/daily).  
It would also have the added advantage of diverting more from landfills, while reducing the amount of trucks on our roads, using up fuel, spewing noxious fumes into the atmosphere, and an end product that would be better in biodigestion or to incinerate or gassify?
