Just a tid-bit of information I'd like to pass along to you guys if you're interested.
If you run your diesel on WVO, or Bio-Diesel, you know about the dregs and questionable oil you have left over after filtering you're veggie oil. A lot of folks save it up and simply "donate" it back to the rendering companies by pouring it into a restaurants dumpster... But if you have a wood burning stove, you can use the dregs, fats, and watery slime found in the bottom of the bucket to make a FANTASTIC homemade "fire starter log".

Start by finding a store in your area that installs carpet, and score [from their dumpster] a couple of the cardboard tubes that the carpet comes "rolled up on" from the manufacturer.
Once you get it home, cut it into lengths that are appropriate for your particular wood burning stove.

Next, score a garbage can full of saw-dust from your local lumber mill.
In a dry [covered] area, spread a layer of saw dust, and pour the dregs/WVO over the sawdust. I use a cheap blue tarp from harbor freight to do this, but a friend of mine uses a plastic tote. Mix it up so you have good coverage, and then walk away from it for a couple weeks.
Over time and with exposure to oxygen, the WVO "polymerizes". In simple terms, it gets sticky and hard. At this point, it's important to point out that you want to keep the sawdust/WVO mixture spread out in a thin layer for this process to take place, and also make sure it's exposed to air. I do this in a corner of my garage where I do all of my WVO-to-diesel fuel stuff.

Once the mixture attains it's stickiness, and the oil has dried out and absorbed into the sawdust, pack it into the tubes. The harder you pack it, the better.
After you've filled the tube, wrap it in wax paper, or a layer of kitchen plastic and set it aside until you're ready to use it.

Keep in mind that while you're making the equivalent of a store bought fire starter log, you cant actually start a fire with these. The cardboard tube is too thick to take a cold flame, but they burn EXACTLY like the store bought ones. Even better in my opinion because the food particles tend to crackle and pop more like real wood.

The benefit of doing this is that you're using up all of the oil you've collected instead of storing buckets full of crap that you've eventually got to find a way to dispose of. You're also putting sawdust to good use, as well as keeping the cardboard tubes out of the landfill. And you're using all of it to heat your house!

***Worth noting***
*If you blend you're WVO with gasoline before settling, DO NOT DO THIS! Only use straight WVO.
*In the same manner, dont do this with black diesel, ATF, or transformer oils of any kind. ONLY WVO
*If you dont run a diesel on WVO, you can still do this with the used oil from your deep fryer or grease from pan drippings
*In my experience, it takes about 1 cup of WVO dregs and about 1-1/2 to 2 gallons of sawdust to fill a "log" about 16" long.
*If you use sawdust to clean up the mess from your WVO processor, this is a great way to double recycle!
*This will not work for the glycerides left over from bio-diesel production.
