[Stoves] Biomass fuel vs animal feed vs fertilizer

[Paul S. Anderson]

Stovers,

When a biomass "waste" can be used as an animal feed or as a fuel in some stove
or furnace, which is more economical?  Assume that the animals and the suitable
stoves/furnaces are present in the same region.

When vegetable oil seeds (sunflower, soya, - name more, please) are pressed, the
product is the oil and the by-product (almost as co-product) is "press-cake" of
some type.  The press-cake is what I am interested in.  Some types (pure or
mixed with other low-value biomass) could probably be compressed into
briquettes or densified into pellets.

Currently, much?? press-cake is used as animal feeds.  Would it be more valuable
as a fuel?  I am sure there are considerable variations and situations, so
please clearly state the circumstances to which your replies are relevant.

Can we assume that the values as feeds or fuels are higher than as fertilizer?
