Producing feed-grade ash is a concern to me. We are selling product into
a predominantly European and Japanese market within Indonesia, both of
whom are very sensitive to animal-based products finding their way
into ruminant feeds. Discovery of animal bone entering our feed,
even if ashed, would result in loss of consumer confidence, as the
consumers are so nervous about scrapie/BSE and the tenuous link to
CJS. As one may recall, ten years ago heat-rendered meat and
bone meal was "completely safe", but the European public have lost faith
in such assurances.

Also, such a furnace will require lots of wood in an area with very
little of it; most farming families have changed to subsidised kerosene
as timber is depleted, and cutting wood won't be advisable. We are
120 kms from a good coconut growing area that could
provide husks and shells for fuel. Biogas would be one possible fuel,
but I don't think the end product justifies it. Millers can acquire
cheap Dicalcium phosphate from China for very low cost indeed,
in bulk or bagged, of very uniform quality, so I can't
see feedmillers bothering to buy our animal-derived ash in tiny
quantities, of very variable quality, at a higher price.

While the ashing is a nice idea, I think I can generate more economic
return with the 350-400 degrees elsewhere, such as running my
boilers in the abattoir to supply my L/S (Lavatory/Steriliser) units for
washing hands and sterilising knives.
