Vegetable Oil SVO WVO waste cooking oil as biofuel

[coachgeo]

Jon, You've mentioned this in responce to threads several times. Maybe I missed it via search...... but have not come across an actual thread on this topic. Can you do so please. Have questions about your process.

How tight do you stuff them? Hydraulic press tight like those who make paper logs or pucks orr?

How do you store them with out the oil leaching out and causing a mess?

Have you tried different material beside saw dust?

No one around here uses that type of carton anymore. Am myself considering mailing tubes stuffed with shreaded paper soacked in veg oil. Any suggestions?

I've had good success with a couple of methods, both using 1/2 gallon milk or juice cartons which are available free at the local recycle depot.



The VO sludge and biodiesel glycerin is mixed with sawdust in a large plastic tub and a garden trowel is used to pack the mix into the carton.

Another method uses a plastic 'milk crate' to hold 9 cartons.



Sawdust is packed into the cartons, then a heated mix of VO sludge and biodiesel glycerin is poured into the sawdust filled cartons.
A 'cubie' box holds 8 fuel bricks vertically for storage and the leakage is minor.

I have an abundant supply of sawdust from heating with wood so I've never tried other materials.

Do you think the wax coating on the carton's help prevent leakage?

How long between when you make one and when you actually use it?

How long have you had one stored un used?

when you poor in the stuff.... how do you know when to stop adding? It assuredely seeps into the sawdust slowly.

Whatever the coating is probably helps reduce leakage

How long between when you make one and when you actually use it?

Typically months, sometimes weeks

How long have you had one stored un used?

over a year

It usually takes two applications to fill as it takes some time to soak in.

Saturation level? Do you end up with a thick paste if you were to scoop it out or does it have a soupy result. I assume a paste but you know how assume could be spelled.

It depends on temperature. Bricks can be 'squishy' in the summer but hard in the winter.
