A plant like that is highly unlikely to burn waste paper, you can bale it up and sell it; lots of the 50’ regular height boxcars you see leaving box plants are filled with waste paper. That’s likely the smokestack for some old boiler (maybe in operation or not still) which would have made steam for the corrugator or whatever else they may be doing. Source: I worked for PCA for a few years right out of college and, while we didn’t have a corrugator at my little sheet plant, we still got all the safety stuff surrounding boilers sent to us on the company wide email alerts, and we baled up our waste paper from cutting the sheets into boxes/displays and put it on trailers to ship out.
I didn't mean the paper I meant the dust--notice the pipes from the cyclone dust collector towards that stack. And it looks pretty new. Either way, it'll be on the model!
