Like [email protected] said, into bottles and recycle if you can. I’ve also had good results with:

• paper towels - this can take a lot, so reserve those mostly clean ones in a bag/bucket for later use
• sawdust in a small bucket that I keep in the garage - dump it into a trash bag and throw out once saturated
• Japanese cooking oil solidifier - this stuff is incredible and turns oil into a paste that is easier to throw out

into bottles and then put bottles into regular trash, there are also companies that recycle oil into biodiesel but i dont think they take regular consumer oil unfortunately
