Utilizing Bio-fuel Beyond Experimental Use

grumpyman writes "A C$14 million factory near Montreal started producing biodiesel fuel two weeks ago from the bones, innards and other parts of farm animals. At full capacity plant will produce 35 million liters (9.2 million U.S. gallons) of biodiesel a year, the greenhouse gas equivalent of removing 16,000 light trucks or 22,000 cars from the roads."

Premptively, let me make this very clear so we don't need to have the same discussion everytime biodiesel comes up.

First, biodiesel has a positive energy balance, to the tune of about 3.2 units out for every unit you put in. http://www.nrel.gov/docs/legosti/fy98/24089.pdf

Second, biodiesel is 78% carbon neutral with regard to greenhouse gas emissions (see previous pdf). That is because the majority of the carbon emitted when you burn a gallon of biodiesel was captured from the atmosphere when you grew the plant to make the vegetable oil. However, the methanol used to make the biodiesel (fatty acid methyl ester) is made from natural gas, at least in the US. You could make 100% renewable ethyl ester biodiesel from ethanol, or make methanol from landfill recovery biogas, but we don't currently.

Third, soy and corn oil are crummy crops to make biodiesel from. But that's where the lobbying money is right now. Other plants have much higher yields.

Forth, no, it isn't a question of "food or fuel"? We can do both! Whenever you hear that argument ask yourself whether the person is well meaning but misinformed, or as been happening recently, is part of astroturf campaign to preserve the status quo of the petroleum economy.

Re:Experimental?

I've posted this before, but I've been using straight waste veg oil in diesel cars for years. Some older diesels don't need any modifications - the PSA diesels found in Volvos and pretty much any French car (Peugeot, Renault, Citroën) run quite happily. You *do* need to find one that has a Bosch-type pump, otherwise you'll get about 1000 miles out of it before the pump seals break up. If it's very cold (over here in Scotland very cold is below 4C for more than a few days) you can chuck a gallon of unleaded in on top to thin it out a little.

I found that in my Citroën CX 25DTR T2 (2.5 litre turbodiesel) I had quieter, smoother running, less exhaust emissions and a small increase in power. I could increase the boost (and thus excess fuelling) quite a bit without hitting the smoke point or cooking the turbo. All this from (effectively) free fuel.

I have seen them. I don't see what you describe.

I live in Denton, TX. The City has it's own Biodiesil Plant, one of the first. All the city vehicles run on B20; all the city trucks, heavy equipment, garbage trucks, etc...

Even though, its not 100% biodiesil (B20 is 80% diesel 20% biodesieal) they use a remarkable amount of it. There are a few more public biodiesel pumps in DFW area, and I think one other city around here uses it for thier equipment.

Ours plant is out by the land fill, and basicly all the vegetable oils, from restaruants and farms etc.., get processed. Pretty cool, and not experimental at all.
