You are right! I was trying to point out the gummit friends that
will come calling on Andrew in a much lighter tone.
Used fry oil is traded as yellow grease. Yes, it is highly variable.
Most of the grease collection tanks are left open to collect
rainwater too... Water and used fry oil are not good company for
those who want to make BioD.
Even at 20 million gallons per YEAR, yellow grease is not a good
feedstock because of its variability.
It can be handled in small batch plants, but most homebrew BioD
plants do not have adequate facilities to make good BioD, and dry out
the water and glycerine/soap.
It is not something I could recommend for a small lot in DC.
Yellow grease does not biodiesel make folks.
Been there done that. Yellow grease will not support a transesterfication
chemical reaction that is dependable or repeatable. By definition yellow
grease is chemical combination of any fatty acid source available to the
collection company.
In 2007 I was the design engineer for a large commercial bio diesel plant
with production capacity of 20,000,000 gallons per month, design through
certification. We took a hard look at using Yellow Grease because of the
trading volumes available on the market. Bottom line, NO.
Use clean oil. Remove all water, Remove all solids, Do titrate each batch
to learn what you have and adjust the chemistry for each batch as necessary.
The EPA will become your "New Friend" the instant it is discovered you are
making anything with chemicals.... followed by Homeland Security, BATF, and
about a dozen alphabet soup government shops you never heard of till then...
All of them have the motto:
"We are from the Government and we're not happy until you're not happy"
Time and cost to pass all the government regs and controls, 2 yrs.8 months,
$6.4 million in legal fees and added compliance costs.
Time and cost to build out plant to production, 126 days. $2.9 million
And we won?

Andrew, since you are a card carrying liberal, we know you would not dream
of not paying the appropriate fuel taxes so add whatever the DC
tax is, plus
the federal tax. This is in the neighborhood of $.50 per gallon. Now
your costs, not counting time, are $4.63 per gallon. How much are you
saving? Then you need to buy a pickup to gather oil, etc, etc.
NO, NO, Andrew will need to get a nice battery operated Prius to haul oil
for his veggie Benz!
