Copper is in high demand because it is used in construction both here and throughout the world, plus in everyday appliances, cars, wiring, computers, motherboard thingys....just about everythying.
It and Aluminum go for pretty good prices. At the salvage/metal recyclers, its $1.30 per/lb near me for clean copper. I forget what it is for dirty. Aluminum is $.38 per pound clean or $.22 per pound dirty (paint, steel bolts, plastic on it).
I have been needing some extra cash, so I helped a guy clear some property he has that people have been using as an illegal dumpsite. I used a utility trailer and collected quite a few thousand pounds of bau-met (scrap steel). I have made $222.97 in the past couple weeks........thats at $3.25 per 100 pounds...so like over 6,000 lbs. It ain't worth a lot for the steel....but it was mostly easy work since it was all together and I didn't have to travel out of my way to pick it up.
Then yesterday, I took a about 40lbs of insulated wire (bad jumper cables, wires from houshold appliances and a/c units and washer/dryers) at $.22 and made $8 and then sould 300 pounds of dirty aluminum for like $66. So thats $296.97 I have made in the past couple of weeks working for a few days only a couple hours at a time. It helped me buy some books I have been wanting to read and also some new shoes, etc.
I have noticed some other illegal dumpsites with just tons and tons of scrap metal and I figured it would be worth it to contact the owners just to see if they would let me clean up their property for "free" if I keep the scrap. Plus, its like a mile from the recyclers, so super easy on the gas and time.
