40 + mpg out of a mid size truck?

[Christ]

The above post is advocating the use of BD over SVO/WVO, due to both the complications involved with using SVO/WVO and the dangers, both to engine/vehicle, and environment/human life.

FYI, In case there was any confusion.

[JacobAziza]

I got it. I deleted my last post before you responded

[Christ]

Woops! Didn't notice that you deleted it... O well, I'm sure someone else could have been confused by it, as well, so I'll leave it there for clarity.

cmon christ, surely you can attest to the "manufacturing" environmental impacts

not all rigs who carry the fuel run on bio, in fact a lot of them still use petro diesel

and the rigs are one of the main street-polluters



driving 60 miles for a free couch doesnt really mean free after all

now im not saying anything bad about bio, in fact i think its great

but i was paying around $4 for bio while i got veggie for free

so i was able to do a 50/50 blend on bio-veggie


$2/gallon FTW

You could always just brew your own, it comes out to about 0.90 USD per gallon if you find the best deals on methanol and Lye. You could also use ethanol to brew it, and that would allow you to save even more, since you can get grain ethanol from most farmers free.

So where's the manufacturing impact if you're using a naturally occuring alkali and alcohol that comes from rotting silage?

Besides, by the time you get done filtering out the WVO, doing everything else that some people like to do with it, and then spending assloads of money on building a fuel system that will accept it, and in some cases, still having problems with it, it's just cheaper, easier, and more friendly to everyone (except some random company that's making a profit from their fuel systems) to make your own BD. Now, if you don't have the means to do it, that's another story, but I will never advocate using WVO/SVO for fuel, and neither does the US EPA. It's not approved, and if you're caught using it, you face penalties, fines, and jail time.

[alohaspirit]

true enough but did you read those links?

personally i think the shops and stores throwing bricks of used oil
in the landfill should be the ones to face penalties, fines, and jail time
(dumpster diving is illegal too, but we do it for the greater good)


as a homebrew, biodiesel is dangerous
a lot of it is caustic and i wouldnt want it around my family
(my reason #1 for using veggie)
a lot of homebrewers have a dedicated barn/shed for it and understandibly so
another thing is that it produces soap as a byproduct
have you ever tried to sell soap?

im not a hot chick or a knitting grandma type so no one buying it from me thats fer sure
and ive known a couple people to just throw that into the landfill which is a big no-no


i spent less than $100 for a complete filtering system i made myself
(my backyard is the size of a car so thats reason #2)
and i drove a 300TD mercedes which needed no intense system


ive been in the scene for a while and most guys are
pro-bio/pro-veggie/anti-petrol with some debate over preference

curious as to why youre anti-veggie?

Glycerine. That's all.

And making BD is only as harmful as the operator lets it get. Methanol is no more dangerous than gasoline, and people store large quantities of gasoline in thin plastic containers, isolated from any source of ventilation and often in direct sunlight.

Sure, lye is caustic. So is Drano.

The 300TD I believe has an IDI engine, and regardless of that point, it's old enough that it doesn't need a complex fuel system. Newer vehicles require intense filtering and basically bullet proof fuel systems because of the ECU-controlled components and exact standards to which they adhere during operation.

As far as selling soap, yes. I used to breed sheep, and soap can be made from lanolin, which is extracted after carding/pressing wool. It requires potash and lye, as well.

Throwing glycerine soap in a landfill is still far better than letting it hang in the air. It breaks down rather quickly in the environment, providing sugars for bacteria, which speed the degradation of trash, producing a controllable source of pure methane, which can then be used to make methanol, which is then used to make more BD, etc. It's a logical circle,actually.

Glycerin, as I pointed out a few posts back, also has uses in medicine, farming, and personal hygiene. The amount of soap produced is a component of the operator, not the batch. Soap production can be minimized with proper titration techniques, the excess methanol can be washed from the batch and recycled back into another batch.

Dumping vegetable oil can be a problem, but usually isn't, as long as it's done responsibly. Bacteria can break it down fairly quickly, making it less harmful than bubble gum, actually. (I've never tested that, it came from a meeting I attended at a local landfill, so it could be complete BS.)

The base waste component of BD is glycerine, raw. The particulate emissions from WVO/SVO contain triglycerides, a compound form of glycerine, which is harmful. The methoxide brew breaks down the glycerine from the chain and replaces it with methanol, making it fairly inert.

[Christ]

If you have a preference, or you want to use it, I don't fault anyone for it, but I will never use SVO/WVO as a fuel, for those reasons.

The kicker is that there haven't been enough environmental studies done to truly divulge the impact of glyceride compounds on the environment, so this all could be useless conjecture when compared to the effect of things that you breathe every day anyway, but I'd still rather be taking potentially harmful particulates out of the air, not putting them back in.

i guess my one word answer is simple: aquifer


our landfills are bad enough, we dont need waste oil leeching into our water system

landfills are typically too tightly packed for even biodegradables to degrade properly

“Typically in landfills, there’s not much dirt, very little oxygen, and few if any microorganisms,” says green consumer advocate and author Debra Lynn Dadd. She cites a landfill study conducted by University of Arizona researchers that uncovered still-recognizable 25-year-old hot dogs, corncobs and grapes in landfills, as well as 50-year-old newspapers that were still readable.

[Christ]

Landfills are required by EPA regulation to be lined, as well, and largely, they're being utilized as sources of energy. A landfill can be thought of as a giant battery with a fairly large supply of energy. Then again, so can a cow, I guess.

Our waste oils from the fryer basically end up in the septic tank. That's been done here for 15 years, and the septic hasn't been treated or pumped once in that time. Before my Father moved in to the house, the Septic was pumped at least every 3-5 years, because it kept backing up, and my Father's sister and brother in law used to put every "help my septic tank" chemical known to man down the toilet to help it. I kept telling them that wasn't the way it worked, and they always "knew better than me".

My Father took my word for it.

I can agree that WVO shouldn't just be dumped wherever, but I still will not agree that it's viable as a fuel. It's just too easy to make it into BD (often, the same energy you'd expend filtering and etc...) to ignore the potential ramifications of it. And even if not harmful to anything, turning triglycerides into raw glycerin still will have an available marketable aspect, if even just as fertilizer/pesticide.
