At the current copper price only the home etching market does not reclaim copper.
My father years ago needed some brass plugs in thousand lots on a mine, and did a costing as to what it would cost him to use the in house lathes, operators and tooling to do so, then went and asked a few for quotes to see if his calculations were correct ( easy way to check the math and assumptions you make). The one he accepted came in at the cost of the material to make it from the brass bar, nothing else. He called on them and asked how they arrived at this price, as it was exactly the same as his calculation for raw material. They replied that they would pay for the tooling, labour and make a profit from the scrap turned off the plug, as the scrap was about half the mass of the part initially. This local company got the contract right away.
