In most larger cities there are individuals or mobile businesses that will buy your scrap after hours at discount prices. You can find their ads on craigslist, offerup and elsewhere. Sounds like they're taking up some of this. Agree with 520 though too, from a labor perspective it really only makes sense if you're adding a second and third shift to baler, shredder and granulator operations (or depending on the yard's volume, upgrading and sorting materials).
