I know that some oils are made from recycled material. Back in the Stone Age I used a recycled oil called Raylube for my late Pop's older car. It worked pretty good in a 1952-ish engine even though it was rated SA.

Someone told me that Super Tech uses recycled oil. I do not know if that report is true or not. Where does a lot of other recycled fluid go? I know that a lot of places drain their waste antifreeze and oil into a common sump. Who buys it and how does it get processed? I am just wondering. It is a resource and someone must find uses for it.
