So I got to wondering - our watermelon* friends (including actress Daryl Hannah whom I can almost forgive for her politics) would have us solve the high cost of gas, the mid-east crisis, global warming, and probably world hunger too, by simply burning used cooking oil in our cars instead of gasoline - how much used cooking oil is available?
Now, the EIA lists the United States annual gasoline usage for the year 2005 as 383.3 million gallons/day. I know we’re a nation of obese, fried food addicts, but do we generate anywhere near that much used cooking oil?
Here are my (rough!) calculations…
Start with
Q? How many McDonalds are there?
A. Over 30,000 worldwide
Ok, I’m going to assume that 25,000 of those are in the United States. I was going to guess that for every McDonalds in the USA there are 200 other restaurants that use a similar quantity of cooking oil, but research shows that the National Restaurant Association reports 925,000 locations. This yields the shocking fact that more than 1 in 40 restaurants in the United States is a McDonalds!
For the oil usage, I found anecdotal evidence that a typical fast food restaurant generates about 100 gallons a month of waste cooking oil – I’m willing to triple that to be on the safe side, to 300 gallons a month – or 10 gallons a day.
So we have 925,000 restaurants generating 10 gallons of used cooking oil each day, or 9.25 million gallons per day. Compare this to the 383.3 million gallons of gasoline used each day, and we find that perfect recycling of every drop of cooking oil used in America’s restaurants would supply – tada – 2.4% of our fuel requirement!
