There is no further processing. It gets trucked to a site to be incinerated. They had no preference. My consideration is if they were to have a spill, would one way be less hazardous than the other? Or does it really not matter.?

Depends on the facility and the further processing. In Europe each group of photochemical waste has its own waste-code and is to be delivered apart.
Have another chat with that facility and inquire on what they prefer.
