vegetable oil as fuel

["A.D. Karve" <adkarve@pn2.vsnl.net.in>]

Dear Mr. Seaver,
we never had any waste vegetable oil in India.  When we deep fry something
and a little bit of it is left over, it is poured out carefully and used
again. I have heard about the epoxides and other nasty things that such an
oil contains, but we reuse it in any case. Now that McDonalds have come into
India, we may start getting waste vegetable oil, but it would most probably
be used by other eateries in the poorer sections of the town. Because India
is chronically short of vegetable oil, the organised soap industry is not
allowed to use edible oils. The non-edible oils, except for castor oil and
Jatropha oil,  have generally a very dark colour, and generally also bad
smell. Since they cannot be used as such for soap making,  nonedible oils
are broken up into their component fatty acids, which are distilled to
purify them. It is these fatty acids that the soap industry uses. As far as
fuel for internal combustion engines is concerned, people in India have
already started using biogas and producer gas for stationary engines. In not
too distant a future, biologically produced methane may become available as
compressed gas to be used as automotive fuel. The beauty of methane is that
it can be produced from any organic waste and the procedure is so simple
that even an illiterate villager can produce methane in his backyard.
