The far containers (darkest) are waste oil in the form that I collect it from the local restaurants. The orange colored middle containers have been gravity settled and twice filtered. The closest yellow colored containers have been chemically processed to become biodiesel with the glycerin removed.

Are you able to harvest the glycerin for other uses or is it unsuable?
The glycerin is contaminated with methanol. While some of the methanol could be recovered that can be a dangerous (read explosive) process. I don't use the glycerin.
