Waste oil recycling
Waste oil recycling
(OP)
Does anybody know if bacteria, viruses etc. survive in waste oil?
The promlem is the following:
We need reduce levels of oil, fat and grease to enter the grease trap of a fast food restaurant. By using a separating device such as a dipper we will be able to separate a good deal of these components from the kitchen-ww-discharge. The separated oil may blend with the used oil from the fritter machines and the blend be used for recycling (e.g. chicken feed). If e.g. Salmonellae survive in the waste oil we would then help to close the infection chain and the chicken feed might/will get infected.
Does anybody know if these organisms survive in oil or not?

RE: Waste oil recycling
I would suggest to sell used oil to Biodiesel producers. During processes inside Biodiesel plant, no bacteria will survive. That way, you will have also a source of income.
RE: Waste oil recycling
thanks for your post, these are bad new, I hoped that bacteria etc. require water for their metabolism (osmotic pressure on membranes etc.).
Since these oils contain lots of unsaturated fatty acids they require hydrogenation before being suitable for a blend with reg. diesel as we do not have a biodiesel use here in Jamaica.
Sterilizing is too expensive, we have to find something else.

RE: Waste oil recycling
- anaerobic bacterias are currently living in the most difficult environments.
- Even if bacterias are not living inside oil, it will be impossible to avoid their development at oil's surface, where they have all required air and humidity.
- Viruses are even more insidious.
As regard to biodiesel , try Pacific Biodiesel
RE: Waste oil recycling
And the Q.. do bacteria survive in oil? Archaebacteria (not true bacteria, I know, but for the sake of simplicity) have been found thriving in oil reserves deep underground, so yes, certain bacteria love the oil. But you're really more interested in the survival of pathogenic bacteria/viruses (not a single pathogenic Archae have been found as far as I know) and there my knowledge fall short. But my guess is that at least viruses have no problem of surviving. If there's risk of e.g. Salmonellae infection of the oil I wouldn't use as animal feed.
adrianviorel's biodiesel suggestion is good. Otherwise, sell it to someone running an anaerobic digestor.
