Hey everybody, as a school science project we are attempting to make Biodiesel from lard, from a pork factory, the pork is steamed and then put ito tubs where it goes off for further processing , what is left, is Meat chunks, white fat (lard) geletine and a waterlike gravy all neatly seperated into layers by vicosity.
After scooping off the lard we have heated it and let it stand at 30 deg c. adding 22% methanol and 3% lye to 75% oil we get a reaction. good seperation of glycerine and some white spots.
on washing we use about 4litres of water to wash out most of the lye and then bubble the batch for 24 hrs to try to dry.
on the settling stage we have a very clear BD and snow at the bottom of the jar can any body help find out what the white flakes are is it still soap?
there are glucomates added to the meats prior to cooking.
will the lard oil have a low FFA count as it is virtually new.
