One problem with dead persons with no relatives in Thailand is what to do with the unclaimed bodies. When bodies are unclaimed nobody pay to cremate the corpse. Cremation of dead bodies is one of major aspect of Buddhism, it allows the soul to quit the body and to go to hell or heaven in order to wait to next reincarnation. In Thailand there is some charitable organisations that take the unclaimed bodies and bury them in their private cemetery. Each year many corpses are exhumed, monks are invited and a big burning ceremony is organised. In 1998, in one ceremony 40000 corpses were cremated. With economic recession, those foundations don't have enough money to buy more land in order to expand the location where bodies are buried. Some hospitals are full of unclaimed bodies and do not know what to do with them, so they warn about using garbage incinerator !!
