The washed dung will tend to be high in lignin, and relatively low in
cellulose, in that the animal would have digested much of the original
cellulose in the feed. Depending on the degree of washing and the
characteristics of the washed dung, it may, or may not have sufficient
binders to hold the washed dung together in the desired shape.
Experimental work would be necessary to determine if added binders would
be required, and quantities required.
Dear Kevin,
In case the binding properties are affected, that would be a disincentive
to a certain extent. This is because, when dung cakes are made in India,
the dung is mixed with loose materials like straw, etc. ( which are bulky
and inconvenient fuels when used independently ). Here, the dung works as
a binder also - apart from its role as a fuel.
# Good point here! If the dung washing removes binders, and prevents using
the agricultural wastes for fuel, there could be a negative energy
consequence. The question would then be health and fertilizer benefits
outweigh the disadvantages of having to change the way in which agricultural
wastes are used for fuel. Would there be an opportunity for an improved
stove system that burned such agricultural wastes?
Best wishes,
Kevin
