Painting Thread 1 Something Something: Paint

My ignorance of how to dispose of toxic paints and paint residue in general was and still is a big part of why I am hesitant to paint. What if you go outside to do plein aire painting with paints that you cannot dispose of easily? I would assume that you'd need to haul a big bag full of items to help you clean up your mess once you are done painting. You would basically be a pack mule and the whole experience would be generally unpleasant (to me at least). These are just some of the multitude of questions I ask myself and search for online with no easy answer.
