Fuel from anything?

Even if we don’t have the technology currently, do you think its possible to get fuel for a car from anything? For example, is it possible to somehow turn clothes into fuel? plastic soda bottles? old high school yearbooks? There has to be something out there.

You’ve been watching Back To The Future again, haven’t you?

I LOVE BACK TO THE FUTURE! ITS MY FAVORITE MOVIE. I know all the words to all 3 of them.
“You’ve got to come back with me!”
“Back to the future!”

Well that’s settled.

Yes, it can be done.
It’s been done before, but even a $140/barrel, it’s still more practical to use petroleum.
