On the TV at the moment, there are lots of pictures of dead bodies being cremated outdoors using wood as a fuel. How efficient is that method of cremation and is it allowed in any other country apart from India?

Mr G points me to this:

Is it efficient to burn coal to make electricity and then use that to
burn bodies? Thermodynamics says no.

What do you mean by "efficient"? I've heard that in India some people
are now forced to cremate bodies in their gardens because there are no
other facilities.

Efficient in the sense of reducing the body to ash? Would it need to be
a speedy process?

Adolf Hitler and Eva Braun were cremated in a bomb crater near the Reich
Chancellery, and petrol was used to accelerate the fire. I don't know
how easy it would be to cremate a body without some form of accelerant
but I suppose in India they are accustomed to funeral pyres.

Whenever we have a bird die (chicken or duck), I always burn them now, on
a small bonfire. There is, usually, nothing left apart from ashes. Only
occasionally is a small part of bone left.

Even in a professional crematorium in the UK where temperatures reach about 1000 degrees Celsius, bones that survive the heat have to be powdered in a mechanical device called a cremulator. I don't know what temperature a wood bonfire reaches but I doubt if it is as high as a gas cremator.

Would anyone cremate a dog or cat on a bonfire in the garden? It would
be legal, but maybe there are other considerations.

AFAIK all UK crematoria use natural gas. (Perhaps LPG in remote locations?)

I wonder how that will work when gas is also phased out. You can hardly
cremate someone with a heat pump :-)

Some previous neighbours we had used to complain if anyone in the
immediate area dared light a bonfire. That their neighbours jointly had
several acres of vegetation to trim and keep trimmed didn't seem to
occur to them.

Yes that article covers most of it, It's just the matter of deciding
on a "building" that is acceptable to all parties.

Then there is the small matter of pollutants but there already exists a
trading scheme whereby crematoria without scrubbers to trap mercury can
buy some exemptions from those that exceed the requirement.

Actually I think the gas preheats the system, the heat from one body
then dries the next ready to burn as once the water (70%??) is driven
off most of the rest is combustible. It's then just a matter of all
effluent reaching about 1200C?? for 2?? seconds.

I used to have bonfires of branches and twigs. A neighbour came round to
complain that the smoke was spoiling his washing, hanging on the line.
He wanted me to wait till it was raining before lighting a bonfire -
obviously this would have made it harder to light and even smokier.

He then complained to the council. They rang to tell me that although a
bonfire is not necessarily illegal, it would be illegal if it was judged
to be a nuisance. They seemed unable to define what a nuisance was but
said that if I wanted to be sure of not being prosecuted and if I wanted
to avoid a visit from the environmental health department it would be
best to stop lighting bonfires.

I didn't want to be un-neighbourly so I stopped using bonfires, bought a
good garden shredder which was quite expensive, and now have my garden
waste collected by the council.

My father had a way of banking up a bonfire and feeding it damp material
so all that was visible was a wisp of smoke coming out of the top. I
think it burnt for days, and yielded ash to fertilise the garden.

Once started the furnace runs continuously, but unless they are very
busy and doing a large number of committals in a short space of time
they generally do the cremation immediately following the committal.

The actual cremation itself takes about 75 to 90 minutes, depending on
the size of the body, so if the crematorium is fully booked for that day
then a queue of committed bodies will form as a typical service is
around 40 to 60 minutes. In that case, the furnace won't finish running
until some time after the last committal. But most of the time, there's
enough slack in the schedule to allow each cremation to immediately
follow the committal.

The furnace doesn't run at a constant temperature; it's first pre-heated
before any cremations are done, then after a coffin is inserted it goes
through a cycle of increasing temperatures up to the main operating
temperature, and then allowed to cool back to pre-heat levels once the
cremation is complete and the ashes have been removed. It will be
maintained at the pre-heat level while unoccupied all day, even if
cremations don't immediately follow each other.

These days, it's all computerised - the weight and dimensions of the
deceased are typed into the system and the total burn time calculated
accordingly. The only thing the staff have to do is press "start" -
everything else follows automatically. But it still has to be observed
throughout, just in case something happens that hasn't been allowed for
in the calculations (such as people smuggling forbidden items into the
coffin of the deceased, which can affect the cremation time), so if
necessary the staff can adjust the temperature, the airflow and the time
manually to respond to these.

Some religions insist, or at least prefer, that the actual cremation
itself is witnessed, and it's not unusual to get such a request even
from non-religious families. So most crematoria have a facility for
allowing a small number of witnesses (usually just close family) to go
backstage, so to speak, and observe the coffin being placed into the
furnace and the gas burners started. The door to the furnace is not
closed until those present can observe the coffin starting to burn.

(All of the above learned on an incredibly interesting VIP visit to the
official opening of a new crematorum near where I live, in the course of
which we were given a full behind-the-scenes tour and a detailed
explanation of how it all works).

It takes a lot of energy to vapourise the water content of a body.
Do crematoria use "condensing boiler" technology? That would certainly
help a bit.

I didn't know that --- I thought religions with rules about funeral
procedures generally didn't allow (or at least favour) cremation.

I have to admit, that does sound interesting. I've only seen a couple
of steelworks (two different kinds, though).

I believe that Hindus and Sikhs are two that do, and of course they
generally use an open-air pyre in countries where they are the dominant
religions. See, for example, this website:

https://funeralcostshelp.co.uk/types/hindu-funerals/

According to Hindu tradition, the eldest son in the family must light
the funeral pyre. As open funeral pyres are illegal in the UK, the
modern equivalent is for him to press the button that starts the
flames.

The deceased's close family, who must witness the cremation, will pray
as the eldest son circles the body, either prior to putting it in the
incinerator or circling the incinerator itself.

And also here:

https://beyondthedash.com/blog/funeral-planning/what-is-a-witness-cremation/7435

Witness cremation appeals to certain mourners for a range of reasons.
Here are some of the most common reasons a family will opt for this
service when a loved one has passed away:

1. RELIGIOUS REASONS

Some religions prefer cremation to burial, such as in the Hindu and
Buddhist faiths. Often, it is expected that the loved ones of the
deceased remain with the body until it is ready for its final
disposition. In some families, this philosophy includes accompanying
the body of the deceased to the crematory and participating in the
incineration process.

One of the advantages of being a councillor, and even better being a
mayor, is that you get invited to all sorts of interesting places and
things that you would otherwise never even think about visiting.

That was how I learned about witnessed cremations. Someone on the tour
remarked on how spacious and well-presented the area immediately around
the furnace was, with the implication that it didn't need to be as it
was an out-of-sight functional aspect of the facility. To which our tour
guide (who was, IIRC, the crematorium manager) responded by explaining
that, although functional and not in any way decorative, it was a
section that is open to the public on request and therefore has to be
appropriately laid out. And then someone else asked why people would
ever want to be there when the body was cremated, and she went on to
explain about witnessed cremations and how they were typically required
at some religious funerals.

Oops, I meant "indoor" or "industrial" cremations -- I knew some
religions use pyres where they can. I didn't know about the witnessing
requirement, though.

They can also momentarily open a flap to allow a ceremonial puff of smoke up the chimney, for people who want that.

I did once complain about a fire.

The landowner had made a very large bonfire of all sorts of stuff -
wood, building debris, you name it - and then lit it when the wind was
blowing the sparks onto my thatched roof.

He got the point.
