Hooves and horns are both exported and used as raw materials for handcrafted items, as are the bones. Animal blood , although not completely collected at the abattoirs, provides a protein source for human consumption after the application of simple processing treatment. Blood meal is also available in the market as animal feed. Organs such as the gall bladder, pancreas, thyroid, uterus, etc. are wasted but could be useful for the production of hormones. No gut residue is available from abattoirs.
Manure is the main waste product from the pig and poultry industries.
Of the 95 million or so birds in Indonesia, fewer than 10 per cent are raised commercially in units ranging from 200 to 1,000 birds per farm. There is no indication of available feather meal, and recycling of poultry manure to feed ruminants is in the initial stages. The majority of pigs in Indonesia are raised in small numbers as scavengers. Fishing industry residues are often abundant in fish markets. But fish meal is also produced by a drying process using the free solar energy source of the tropics.
