If it's a high volume scrap yard then most of the high volume scrap yards make at least 10,000.00 per day or more.
But that's usually not all profit since they have to pay the employees and rent or taxes on the property and buildings and then upkeep on the machines they use.
But a big scrap yard can be really profitable. But I wouldn't want the headache of one.
Scrap prices rise and fall in the market pretty quick and you really have to know what you're doing with the scrap market and finances because you could lose a lot of money if you don't.
