I recently cleaned out a facility of 170,000 sq ft, biggest job I have ever done. Since there was a lot of factory equipment, I decided to hold an auction, thinking things like electric motors (some of them huge) might sell for what their original purpose was. While I sold a lot of items to people who were going to put them to good use (pickup truck, hi-lo, commercial lawn mower, etc.) when all was said and done most items sold for scrap value. Boy did I get an education! While I did not make as much as I would have had stuff sold to folks who would use them for their original purposes, I was surprised at how high some of the scrap sold for, considering the labor necessary to remove it from the building.
