It was in effect oil firing, the stuff was preheated, so probably not
a bad job at all.

Depends at which point in the process you are talking about, raw crap
will be a tad to wet I suspect <g>, but I'm sure that the dried waste
left over after all treatments have been carried out could be made to
burn - BUT - isn't that by-product far to valuable to just burn, isn't
there other uses to which it is already being put to, I'm sure that
it's used as a fertilizer and in some other process already.

not enough fibre - camel dung is basically compressed plant fibres -
like the recycled paper "logs".

too much animal matter in human waste.

knowsthorpe at Leeds grows some really nice tomatoes tho...

...ah, but the tomato plants at sewage works are usually self seeded
from seeds that have passed though the human gut. Now at many power
stations the seeds probably come from a packet, but the copious hot
water available ensures a good early crop

and already cooked as well?

any way, back on topic...

I find a wipe over with cheap diesel motor oil (15w40) for 8 quid a
metric gallon (5 litres) keeps rust from forming - I also use it as
cutting fluid when drilling.

I'll see what it's like on the lathe if I ever get it up and running -
probably a bit thick, but I'm guessing some paraffin will thin it down.
