is biodiesel less carcinogenic than diesel
 

recent report in yesterdays news spoke of diesl exhaust being carcinogenic,is bio diesl as well?is it as polluting in regards to the atmosphere?

Here you go I googled it for you.





Environmental benefits

• Biodiesel will result in significantly less pollution due to low emissions Carbon Dioxide (CO), particulate matter, and other pollutants. For example:
  • biodiesel is free of lead, which can cause various diseases, including cancer.
  • biodiesel contains no sulfur or aromatics (e.g. toxic compounds like benzene, toluene, and xylene), which can cause respiratory diseases and cancer.
  • B100 biodiesel results in a 78% reduction in carbon dioxide emissions. It lowers carbon monoxide (CO) emissions by 44 percent, particulate matter emissions by 40 percent and sulfate emissions by 100 percent. B20 lowers carbon monoxide (CO) emissions by 9 percent, particulate matter emissions by 8 percent and sulfate emissions by 20 percent. When B20 is used along with an oxidation catalyst, it reduces particulate matter by 45 percent, carbon monoxide by 41 percent and total hydrocarbons by 65 percent.
  
  
• Biodiesel is non-toxic and biodegradeable and therefore will not harm the environment or people. Unlike petrodiesel and gasoline, it is less toxic than table salt and as degradeable as sugar!
• Biodiesel is much safer to store and transport than petrodiesel. This is because, in addition to being non-toxic to people, biodiesel has a flash point or ignition point of 152 degress Celsius, which is several times better than petrodiesel at 52 degrees Celsius. It is so safe that it can be shipped by common mail carriers!

thanks for the info,makes me feel better.i have a bio pump station available here in ca.

Whenever I spill any 100% biod my dog likes to lick it up. I tell her it can't be good for her cholesterol (sp?) number but she seems to ignore me.

I am not so sure
 

If cooking fume is carcinogenic then I think Biodiesel fume/exhaust is similar, may be to a lesser extent.

Identification of carcinogens in cooking oil fumes. [Environ Res. 1999] - PubMed - NCBI

That right there is funny! Watch out, the humane society will probably be by tomorrow.:eek:

as far as i know, biodiesel is much safer and environmentally friendly on all fronts, except NOx emissions

I hope you're joking. Although the raw material is food grade, it uses methanol and sodium hydroxide in the transesterification process. The methanol should all be consumed by the process, and the lye is a catalyst to be washed off, but I wouldn't trust that the finished product is clear of all traces of methanol and lye.

I've reacted over 10,000 gals of the stuff, and consider myself pretty good at it, but I still won't lets kids or pets near it.

I read your report and maybe I can offer an explanation.

To my knowledge, no cooking oil in the human universe contains benzopyrene because it is poisonous. Yet it was found in the AIR SAMPLE of the report's location, in Taiwan.

Think there might be benzopyrene in the air in Taiwan? After all, you can still buy and use carbon tet to clean things there, but we stopped that 30 years ago.

I suggest that the benzopyrene might have been in the air, not in the cooking oil. And it got swept away with the "air sample"

Design of experiments has a lot to do with the conclusions.

If done in a lab, I didn't see that anywhere and my comments have to be taken in that context, then.

PS: Vote foir Pedro and Biodiesel :D

Biodiesel is less toxic than table salt and biodegrades faster than sugar.

LOL Ever seen what spilled biodiesel will do to a patch of green vegetation? The stuff works better than roundup.

Regular cooking oil will do the same thing.

To a lesser extent, yes. But we already know that "regular" cooking oil is pretty toxic stuff too, especially (but not exclusively) to plants. Much research has been done in an attempt to use modified vegetable oils as commercial herbicide alternatives. Long before someone stumbled onto the process for making biodiesel, researchers used a a similar reaction to create an herbicide component that could reduce the need for more complex, and costly, organic herbicidal compounds.

Everyone in this discussion has avoided disputing the OP's concern regarding how carcinogenic biodiesel exhaust is relative to diesel exhaust. The fact that biodiesel has a relatively low toxicity in its storage state is irrelevant. I don't know that any studies regarding the long-term health effects of exposure to biodiesel exhaust exist, and the studies of carcinogenic effects of diesel exhaust are hardly adequate to draw any conclusions with regard to public health. I do know that there is no denying that diesel exhaust, at some concentration and term of exposure, is carcinogenic. So is gasoline exhaust. High concentrations of biodiesel exhaust probably is as well.

We know that biodiesel fuel produces smaller amounts of HC, CO, and sulfur, and that it is carbon neutral, so it is probably better than regular diesel as far as air quality is concerned, but I don't believe that anyone can state, as fact, that biodiesel exhaust is more or less carcinogenic than regular diesel exhaust. For that matter, there really hasn't been enough research done to establish how carcinogenic regular diesel exhaust actually is, and, afaik, no specific component of diesel exhaust has been identified as a carcinogen.

as will a pile of table salt, or sugar...

however, sugar is a great remedy for urine from animals on your plants... the carbon neutralizes the nitrogen in the urine....

bio is definetly safe i drank about a cup of it and i was just fine and im still kickin
