Long post, but very interesting story that appeared in this week's
The Australian Financial Review newspaper (3rd June 03).

The ethanol dream runs on empty
by Jason Koutsoukis and Ian Howarth

Nearly three months ago,
Some of you may already be aware of the huge media scare campaign
against ethanol-blended petrol in Australia. Here is a great story
that appeared in the Sydney Morning Herald, Monday April 28 2003:
-
Ethanol fuel line has motorists labouring under
We can get fuel from fruit, from the sumac by the roadside, or from
apples, weeds, saw dust; almost anything. There is enough alcohol in
one year's yield of an acre of potatoes to cultivate that field for a
hundred years. And it remains for someone to find how this fuel can
be produced
Following some pretty serious scaremongering over the past few
months, the oil companies have launched an intense campaign at the
service station level to denigrate the use of ethanol in the Greater
Sydney/Wollongong Basin.
The tactics being employed are similar to those used by the oil
SAFF (Australian Farmers Fuel) is the only company retailing
biodiesel in SA. Some weeks ago, Trade Measurement (State Govt)
stopped by SAFF Head Office and sealed its biodiesel pump -
preventing any biodiesel from being legally sold - because the pump
is a diesel pump and therefore not
On Thursday 17th October, an official from the Govt. Department of
Weights Measures visited a SAFF service station in Adelaide, South
Australia, and decommissioned its B100 Biodiesel pump.
This SAFF service station is the only retail outlet for biodiesel in
South Australia.
The reason for
Thanks to Paddy for forwarding me the Canakci/Van Gerpen
study Biodiesel production from Oils and Fats with High Free Fatty
Acids.
This paper should be of great assistance.
It is worth mentioning here that the pretreatment of the FFA's

We would be using standardised WVO, with FFA 10% to dilute the
greasetrap oils (from 85% FFA to N%FFA). However, this may not prove
economically viable. I will keep you informed of the results of any
experiments performed as to FFA limits.
I noted in Keith's link, an option that may be the
Still in regard to FFA, I will be blending in some wvo to bring the
levels down to a more managable level.
Would most appreciate any indication of maximum ffa level that could
be handled by a 2-stage acid-base reaction, at standard pressure/60
degrees C (to minimise capital/running costs).

Does anyone have experience in processing feedstocks with very high
free fatty acid content (up to 85% w/w)?
Also, any information as to the relevance of acid value of
feedstock for biodiesel? The two feedstocks that I have available
have acid values of 93.6 and 8.1 respectively.
I am able to source large quantities of the high ffa feedstock (FFA

Would the same process, under high Temperature/Pressure, be
sufficient to convert feedstocks of this
cheaper than fossil diesel.

Canola-based B100 biodiesel is available at the bowser at SAFF Head
Office service station in Pooraka (northern suburb of Adelaide, South
Australia). Retail price is 85.9 cents per litre, the same as
petroleum diesel. SAFF [Australian Farmers Fuel] is a fully
