With all due respect to the University of Minnesota, composting of food waste
including meat and bones is commonplace. Composting is the recommended method
of disposal for farm mortalities such as poultry, hogs, and cattle. Fish
waste, cheese, spoiled milk, whey, and other items are composted.
I have to think that who ever wrote the article for the univeristy assumed that
the backyard composter would not be attentive to the process and, therefore,
the meat and such posed a potential attractant.
I have seen thousands of dead, whole chickens dissolve in a compost windrow in
a few days with no residue and no vermin attracted.
If it is a properly build pile, you can compost anything that was ever alive or
made from something that was alive. Even potentially difficult contaminates
can be composted in a method know as bioremediation which is just composting
with a specific purpose.
