Burning Out: What Really Happens Inside a Crematorium,
Cremation
Cost is one factor.
Cremation is nowadays done in specially-designed cremation units, but don't call them ovens and don't call the process incineration. The cremation units have a primary heater and an afterburner for the exhaust gases.
What's left is a pile of bone fragments and ashes, and after removing implants that had survived the cremation, this pile is often crushed further to a powder.
For anyone who does not like burning and the exhaust that it makes, there is an alternative:
Alkaline hydrolysis (body disposal). It is heating a body at 160 C / 320 F in a lye solution under enough pressure to keep it from boiling. That solution becomes a green-brown liquid and the bones become soft and easily crushed. That liquid is usually disposed of in the local sewage system.
It was originally invented to dispose of cows that were suffering from Mad Cow Disease.

Then there are religious problems. Christian churches have long frowned on cremation, because they want a body to be ready to be resurrected when Jesus Christ does his Second Coming. But as Bertrand Russell has noted in "An Outline of Intellectual Rubbish",
But some other religions are more accepting. Hindus have long accepted cremation as legitimate, and some crematoriums let the deceased's oldest surviving son start the process, in accordance with Hindu tradition.
People's cremation ashes are usually put in urns, and those urns are in turn usually put in a building called a columbarium, a sort of cremation cemetery.Four decades ago, less than 5 percent of Americans were cremated. Now that figure stands at nearly 50 percent. This is how cremation actually works, and the story of what happens to a culture when its attitudes about memorializing the dead undergo a revolution.
Cost is one factor.
Another factor is cemeteries running out of land. Rosehill itself is expected to run out in 15 years.“Less expensive alternative” may be putting it lightly. Rosehill charges just $180 to cremate a body, although the urn, flowers, and service are extra. A grave, by contrast, can cost $2,500, plus an additional $1,500 to open the ground with a backhoe.

But over the last century, many Xian churches have come to accept cremation, even if not to endorse it.In this connection the orthodox have a curious objection to cremation, which seems to show an insufficient realization of God's omnipotence. It is thought that a body which has been burnt will be more difficult for Him to collect together again than one which has been put underground and transformed into worms. No doubt collecting the particles from the air and undoing the chemical work of combustion would be somewhat laborious, but it is surely blasphemous to suppose such a work impossible for the Deity. I conclude that the objection to cremation implies grave heresy. But I doubt whether my opinion will carry much weight with the orthodox.
