Processing waste Fryer oil into bio DIESEL requires more than just filters and evaporating the water. Things include chemically strong base (Lye) and an alcohol (Methanol).
Both compounds are extremely reactive and if mishandled can either burn or poison someone very easily. Plus we also have the washing process to clean the final product.
So at least, he is looking at a wet environment, flammible storage, chemical storage, electrical heating elements, pumps, and few other assorted hazards.
Sounds like it should be a piece of cake.
If he is looking to use Vegatable oil to power engines or burners, then he has to deal with filtering, drying, and mixing of the oil into conventional petroleum fuel. Plus heating the oil prior to use in cold weather.
Absolutely no hazards there either.
If all of those hazards are addressed, then go right ahead, but please notify the local fire department so they know what hazards might be there if a fire does occurs.
