Basics

Often abbreviated as UCO
A Waste Product from Cooking; Largely Deep Frying
A Feedstock in Bio-Petrochemistry
Can also be used directly (albeit uncleanly) in Waste Oil Burners
There may be some minor distinctions but for now “Waste Vegetable Oil” and “WVO” will redirect here

Things to Note

(From User: Eric via hands on experience)
- It can contain a decent amount of solids so most plants incorporate filtration or Sedimentation (sometimes with a Filter Aid or Flocculant ) phases
- It can become quite viscous (albeit not as bad as Sixth Oil ) so Heater Coils are often needed
  - Although these then need to be kept clean
It can be quite stinky so Odor Engineering Controls are advisable
Unlike many petroleum products which may repel or even kill insects and other pests, WVO ATTRACTS Mosquitoes and other bugs so Vector Control / other info related to controlling them such as Bug Lights and Air Curtains etc may be relevant
Feedstock Variability/Contamination are worth considering
Although heavily Fuel Agnostic systems or a policy of “Gasify and Start Over” (Via G2L etc) may alleviate this issue

Fats, Oils, and Grease
- A related term, although it includes heavier solids recovered from Cleaning of Equipment etc
Grease Trap (A Method of Collecting Irresponsibly Disposed of UCO, or Small Amounts that Accumulate in Commercial Kitchen Environments)
- A similar device is used for Car Washes / Vehicle Wash Bays albeit it yields a heavy/nasty sludge
Kitchen Exhaust Cleaning (Need to look into recovery systems)
