Used oil form gearboxes,
engine crankcases and transmissions that originally came form crude
oil contain carbon that was collected from the atmosphere eons ago
by plant life. The farmlands all across the United States are in bad
need of carbon.
Processing these waste
oils in proper built digesters using special microbes can completely
clean up the used oil and turn it into plant foods.
Waste oil from the North
West part of the country and from Texas that was processed with slightly
different digesters in those two locations, but using the same microbe
tested the same day at the same lab in San Antonio, tested slightly
different in plant nutrients but both tested clean of any toxic or
Processing and using waste
oil in this manner is probably the most environmental sensible way
of disposing it.
None of the carbon is
lost back to already over burdened atmosphere, but instead waste oil
can be used to grow plants that take carbon from CO2 in the air and
release oxygen back.
In my greenhouse and in
the garden I grew healthy plants using only the liquid from the waste
oil digesters, no other fertilizer. I use it heavy, 1 pt. Per gallon
of water or light, 1 tablespoon per gallon. Rates do well, I even
used some 100 percent on four plants and they did well, no burning
or any harmful effect.
I also sprayed it on tomato
plants that were covered with aphids. It knocked some off but not
completely. I believe at the correct dilution, probably more concentrated,
it may be a fair non-toxic pesticide.
Time hasn't permitted
me to do all the testing necessary to find the correct amount for
each plant, environment and such. I don't think you could over
use it and hurt plants.
The only problem I have
found is the slow process or time it takes to digest the oil. However,
I am sure this could be overcome with enough research.
