WVO SWAGs for public beta test

We did some estimates recently I'd like to share. Feedback and corrections requested. And I promise to take a break from the software metaphors after this...

A search at Environmental Services for Maricopa County [1] returned 21155 entries for licensed "Food Establishments":

Using 50 gal / month / licensee [2] for round numbers equals 12,693,000 gals WVO (waste vegetable oil) per year in the greater Phoenix area.

Using 22 lbs of C02 per gallon of diesel fuel [3], and reducing that by 78% when running B100 [4] equals a net CO2 reduction of:

217,811,880 lbs (108,906 tons) of CO2 removed from the Valley [5]

by converting that WVO to biodiesel and displacing the petroleum diesel that would otherwise be used here.

[5] actually, the 78% reduction is described as "life-cycle CO2 emissions" compared to petroleum diesel, so the local CO2 reduction is probably less.
