disposing of WVO and methanol
I started messing with bio diesel when diesel was $4/gal in the US and I had just bought a diesel truck

THe price has fallen and the truck is not running and I have moved to a small house.

I need to dispose of about 400 gallons of WVO and half a drum of methanol.

I live in a warm place where the foliage can consume a house in about 15 years. And where I can legally burn large amounts of foliage.

how will WVO and meth breakdown in the soil?


Clueless and curios about bio diesel

I'm not sure how long WVO would take to break down in soil but I suspect it would be years. A common use for WVO is livestock feed. If you can't find someone to make biodiesel, maybe you can find a cattle farmer!

A pig farmer told me that when he fed vege oil to his pigs they developed "scours." I very much doubt that animals can healthily consume neat oil.

"Methanol is readily biodegradable in both aerobic (oxygen present) and anaerobic (oxygen absent) environments. Methanol will not persist in the environment. The half-life for methanol in groundwater is just one to seven days"

It seems like you have answered your own question and should look into (safely) burning all of it off, assuming no one steps up to relieve you of it for their own uses. It goes without saying that methanol is very easy to burn. WVO burns pretty well if added to an existing fire, and burns like mad if you have a way to "aerosolize" it -- i.e., spray it as smaller droplets into a fire barrel by using compressed air, etc.

I once burned off a full 55-gallon barrel of old-nasty-not-worth-converting WVO in just ten or fifteen minutes, just by tossing big slugs of the oil into a burn pit that already had a well-established hot fire going in it. Do be prepared for a lot of heat when the fuel hits the flame...

WVO should be processed appropriately before it can be used as feed for animals.
