I’ve seen it done before and was wondering if it’d be worthwhile investment to add kitchen oil removal to my existing family’s trash service and basically get paid to collect fuel for my garbage trucks.

I can speak for rapeseed oil specifically since I have some experience driving a truck quite a few years ago that was converted for vegetable oil fuel;
Rapeseed oil attacks engine hoses, specifically those that are synthetic. The only ones that don’t constantly dry and leak from the fuel itself, are the natural rubber ones. This also includes gaskets and stuff, which means that you may save yourself a lot of trouble if you buy the truck new and order the engine with rubber gaskets and rubber hoses for everything that will come in contact with fuel.
Is it like this with all vegetable oils? I have absolutely no idea. But it feels like it’s worth warning you about so that you don’t hit that landmine without seeing it coming.
One of the super-convenient things about running a truck on vegetable oil is that if you get a fuel leakage (no matter if it’s due to a breakdown or a crash) is that the fuel is easier clean up; reasonably small amounts may not require that you call out an excavation service on your insurance company’s dime because you just released something extremely toxic that will soon reach the ground water.
If you order a trash truck new, remember that there are rapeseed oil based hydraulic oils too (same problem with hoses!) for the press, and that can save you a lot of headache next time you bust a hose right next to someones brand new hedge…
Oil that you collect must also, obviously, be thoroughly filtered so that you try to drive your trucks on a product that will not clog. The equipment that ensures that you get JUST oil in your engines, do not cheap out on it.
