Does the biodigestion, biogas energy and organic fertilizer industry conflict with the organic composting industry?

I see it as a two step process, the concentrated high nitrogen waste digested anaroebically, to tield a high nitrogen, more stabilized, less gassey additive to aerobic compost, either in the soil itself or a compost pile waitng to be utilized.

Green manure and manure type waste could be digested anaerobically in the first step to produce energy and offset methane and nitrous oxide release.  

How much nitrous oxide and methane would properly composted waste produce? Not very much, but the usual procedure of pumping manure into ponds or pits open on the top to the atmosphere is a GHG disaster.

Composters unite!  Digest your hot waste first.  Generate clean backup power for a renewable grid in the process.  You'll still have plenty of compost, fed with the biodigestor fertilizer.

This also eliminates the pathogen problem.   That first germ killing biodigestion process.

These latest pandemics originate in interspecies manure/food stream intake and the development of resistant mutated strains of pathogens that migrate from species to species.  Bird flu to humans for instance.

It's a big issue.  As big as eliminating GHG?  Maybe, if pandemics start up.
