I keep a few business cards handy of junk men for jobs where a lot of scrap is generated on one job. Otherwise, I have a big scrap metal pile at the shop. It's first-come, first-serve for whatever guy wants to load it up. My "rule" is that they have to take it ALL if they want any of it. Had some guys leave a broken pile of lamps and refractors from troffers, etc. Electrical garbage is mostly metal anyhow, so I rarely get any problems from the scrappers. The only thing I think I pay to get rid of is actual garbage and large quantities of lamps. I take lamps back to the supply house. Those things are getting more and more expensive to get rid of. Seems odd, though, since I'm sure there are more lamp recyclers in business in 2014 than there was in 2004. I'd have thought supply and demand would have brought the price way down, but it hasn't.
