What is Biodiesel?

Bio-diesel is a fuel that can be used to run everything from cars to electric generators. It can be used to run any diesel engine, completely without modification. The engine will run cleaner and need less upkeep over it's lifetime because bio-diesel is so clean.

It is not only a clean fuel, it is a completely renewable fuel resource! It is cheap, and relatively simple to make at home for about 80 cents a gallon or less at current (2007) prices. In fact, you may be able to get the chief component of this fuel completely free!

What is the basic building block of this amazing fuel source? Cooking oil. Vegetable oil. The kind that any fast food place used by the gallon. The kind restaurants pay large sums of money to have removed from the premises. The kind you can get in the grocery store for a few dollars. Bio-diesel, put simply, is made from processing used cooking oil or meat fats, and lye or potassium hydroxide. Easily obtainable materials.


Making the Biodiesel

You do not need a Master's degree in science to make bio-diesel. In fact, it is easier than it has ever been because there are numerous websites where you can obtain Home Bio-diesel Kits.

With one of these kits, which range in price from about $1,800.00 to about $4,000.00 depending on what you want, you can learn to make your own environmentally friendly, low cost fuel in under an hour.

The only by product of making bio-diesel is glycerin, a sticky substance that is natural and can be composted easily in your compost pile to add nutrients to your soil.

Having owned a small restaurant I can tell you that small restaurant owners have a difficult time getting rid of used frying oil. It cannot legally be thrown in a dumpster and must be disposed of in a certain manner. Most would be glad to allow you to remove the oil for them, free of charge!

You will need to run the cooking oil through a filtration process to get out all the food particles before you begin to process the fuel. An average bio-diesel kit will make about 40 gallons of fuel in 24 hours.



How to Make Bio-diesel

Make Your Own Biodiesel Processor

It is also possible to make your own bio-diesel processor from a converted electric water heater, using a conversion kit. There are numerous detailed instructions on the Internet, which I have posted links to, however here is the basic method:

First you will need to remove the cold water inlet tube and the bottom drain and attach the T assembly. At that point the pump will bolt to the T, and the fuel transfer manifold will attach to the top of the pump. The electric elements will need to be rewired to heat only at the bottom of the tank. With a few other tube connections and some wiring changes your bio-diesel processor is ready to go.


Benefits

By making your own bio-diesel fuel you are making inroads into a cleaner environment. You are taking steps to be more self reliant. You are utilizing a renewable energy source that biodegrades harmlessly.

Bio-diesel can be used to run any diesel engine, including home generators. It can be used as a home heating oil. Because the components are made and processed with in most individual countries, it allows a population to reduce its' country's trade deficit and boost the local economy. It creates jobs and benefits farmers.

Not only that but it is good for the engines it is run in, cleaning out old residues and keeping them running clean. It lengthens the life of the machinery it is used in because of it's cleanness so saves money in that way as well. Using bio- fuels could reduce the production of greenhouse gasses by reducing life cycle carbon dioxide as much as 78%.

It is completely legal to create and use your own bio -fuels in most , if not all, states in the United States. Bio-fuels comply with all standard emissions systems requirements. This is definitely something to look into for the present as well as the future.


And the Downside?

Really the only negatives in using bio-diesel is the fact that it is not readily available. This means that if you are going on a cross country trip, for example, you are going to have to tote your own fuel supply or use the regular diesel that you can get at the gas stations you pass by.

The other problem is that due to a lack of understanding about the long term use of bio-diesel and it's effect on engines most car manufacturers state that use of bio-diesel will cause their manufacturer's warranty to be invalid.

All in all, bio-diesel is an excellent choice for both the environment and the pocketbook.

Addendum: Scientific Studies

The Department of Defense and the Congressional Budget Office (in the US) have both confirmed that bio-diesel is the lowest cost, renewable fuel source that complies with the EPA's requirements. There is fascinating information as well as charts at Bio-dieselBasics

Chrysler Group has put over 150,000 miles on it's fleet cars using bio-diesel over the last five years. GM has been monitoring a fleet of over 238 vehicles, using bio-diesel, that have racked up over five million miles- all on bio-diesel. Not one of the cars has experienced any problems related to the fuel.

More and more cities are using bio-diesel exclusively in their public use vehicles. The Department of Defense is using bio-diesel. In fact the DOD is one of the BIGGEST US users of bio-diesel. The car companies do not honor a warranty if you have used bio-diesel. Why?

One reason that they state is that up until recently bio-diesel has not been as carefully regulated by the government as gasoline. There has been voiced concerns that this could mean that there would not be a consistancy in the quality of the fuel. Some feel that switching back and forth between regular diesel and bio-diesel would harm engines. The switch would be necessary during long trips when bio-diesel supplies could be sporadic.

Yet at Fort Leonard Wood, Missouri the Transportation Division has been experimenting with just this very thing for most of the decade. Operation and maintenance for the more than 70 High-Mobility Multipurpose Wheeled Vehicles (HMMWV) studied was unchanged.

The US Navy uses bio-diesel for all non-tactical vehicles. At Guantanamo Bay's Environmental Department they are currently experimenting with the use of used cooking oil for bio-diesel manufacture to run the various vehicles on base. The DOD Great Lakes uses bio-diesel, the Department of Energy uses bio-diesel at three of it's major facilities and the US Postal Service is utilizing bio-diesel more and more.

Perhaps bio-diesel will become something car manufacturers accept when THEY can profit the most from it.

While none of this links to a specific scientific study it seems the trend is pretty clear. Bio-diesel is a safe fuel, a environmentally friendly fuel, and a low cost fuel, at least for now.

As the government gets more involved the price will go up, as well as agricultural issues similar to the ones we see with coffee today. Potentially farmers in poor South American Countries will begin to clear large amounts of land to produce crops to make bio-diesel fuel, totally defeating the positive qualities of it as it is.

This is a great idea.
There's growing concern that commercial production of bio-fuel could actually be harmful to the environment – for instance, they’re cutting down more of the Amazon in Brazil to create farmland to grow bio-fuel!! And the price of corn is rising, because Midwest farmers are selling their corn for bio-fuel which creates a shortage of corn for food purposes.
Using oil that would otherwise be thrown away, and doing it locally, avoids those problems and is the ultimate environmentally-friendly fuel.

A lot of people use the oil from the fish and chips shops to use. At least that is not destroying any crops that way.

Good hub with lots of information

Marye,

Do you have any personal experience of using that homemade fuel for a prolonged period of time? It would be really interesting to hear.

Great hub!

I´ve a friend how use all the kitchen oil he can find to make homemade fuel to mix with diesel, he have an old Mercedes and it´s very funny to smell that fried chips kind of odour lolol.

Willie Nelson began using this fuel in every vehicle he owns quite some time ago and is a huge supporter, to the point that now several places will have the fuel, ready to pump when you pull in.

There was a PBS Special with him on this subject. A few videos available at Google if you search Willie Nelson biofuel.

Read too that some places have started co-ops where all members contribute 'greases and oils' and all pump free...

I am all for this,

Great info there...thanks so much for putting up this hub!

Reminded me to check out how far Willie's gotten in his works on this,

Well, I wouldn't do this then. There is a reason car makers deny warranty. Car engine is a pretty complex thing, and introducing to it chemicals it has not been designed for may or may not damage it. I personally wouldn't take the chances...

Several thousand dollars for the kit, and then several thousand for an engine repair or replacement looks pretty steep to me...

There are numerous studies that prove it's safety.

Misha  says:

Despite it's safety is supposedely proven by mentioned studies, car makers still deny warranty...

Can you link me to at least some of those studies? Those considered authoritative, if possible?

I wonder if some car makers deny the warranty in order to create a prolonged market for pertroleum based fuel?

As for not enough food corn, I think it is an artififical shortage - just like the coffe eand milk dump in the Gulf of Mexico in the early 1950s or late 1940s that drove up prices - US has for decades been selling wheat and corn that is 4-6 years old to the USSR and now to some of the former republics post-1989 breakup. In addition, Pepsi manufactures an artififcial milk available only in the Eastern Hemisphere.

In my state, the welfare part of government refused to give out the free cheese, peanut butter, butter, powdered milk and other things they called "commodities" and simply stockpiled them. Then they gave out minute quahtitites to very few people. Thsi year the Food Bank claimed to be out of food and private citizens grocery shopped and took higher-priced food to the Food Bank. When my community school qualified for the school lunch type program from the food bank 5 years ago , they told us we could have only toilet paper and #10 cans of food - these are the big restaurant sizes - and that we could NOT cook the food on site. Were the kids to eat it raw? They just did not want to give it out, according to their own agenda.

I would get the old corn out of the silos and make fuel out of it. Just my opinion.

Cheers!

Marye,

Thanks for putting that extra info into the hub. I'm afraid, though, it does not answer my question. The link you provided is to the site of cooperative that produces biodiesel and therefore is interested in promoting it. Even they had to publish a couple of important disadvantages of biodiesel. Quote:


Eats away natural rubber fuel lines, and can clog fuel filters on first use:

Biodiesel is such a great solvent that the fuel can eat away at fuel lines in older vehicles-- check to see if you have natural rubber or butyl fuel lines and replace if you do.

Can gel, starving motor of fuel in below-freezing temperatures:

If you live in a climate that experiences below 38 degree temperatures, consider a blend of biodiesel and 10-15% petrodiesel during the coldest months, a fuel heater (in your tank, fuel line, or fuel filter), or an anti-gel additive (Power Service, Stanadyne, and Amsoil all make one).

End of quote

The rest of the text does not have any sources sited and thus does not prove anything.

I'm not trying to prove biodiesel is bad. I don't know if it worse or better than petroleum one overall, and I believe only time can tell this. What I'm trying to say is that biodiesel may not be suitable for existing cars because they were designed without biodiesel in mind.

I think that refraining from using it will be beneficial to your pocket, until there are cars on the market specifically designed to use it.

Just an opinion of a former car engine designer and diesel car owner...

From the info I have so far is that yes, you must convert your car to accept these alternative fuels. So are you saying that even if you do or pay to have done, the conversion, that automakers would still void the warranty and the fuel could still cause damage to the car?

Confused here. I had one car that I had converted from reg gas to accept diesel and it didn't cause any issues.

Appreciate further input...I'd also find it odd for Willie to have converted all his vehicles to accept the used oil fuel if it could damage them....

Dj, I don't know what is included in the conversion you are mentioning - thus I can't draw any conclusion if it is enough or not.

I'm pretty much sure that automakers do *not* have any direct interest in petroleum fuels, so I don't see any conflict of interests when they deny the warranty.

I don't know who Willie is, and I'm pretty much sure he does not have enough resources to conduct proper reliability testing. That thing costs quite an amount of money, and cannot be done properly at home.

I can only guess what car makers don't like, and it most probably is related to high pressure fuel pump and injectors. Those are high precision devices. As all moving metal parts, they have to be lubricated to work properly, and they are lubricated by diesel fuel itself. Changing fuel characteristics can affect lubrication, thus affecting reliability. Again, this is my speculation, I can't say with certainty if this is the case or not.

If someone can link me to a serious reliability research, I can review it for validity. Until then I stay cautious...

looks like hard work, but the way petrol prices are going, it makes sense to start making your own!
