I just scrolled through the free section of Craig's List for a city with a population of about 100,000. There were three refrigerators available for free. There were two washers, two dryers and a dishwasher. All free. All posted within the last 24 hours. You just go and get them.
The scrap value of the average refrigerator is about $50, big ones a bit more. I'd guess washers and dryers would be around $20 but couldn't be sure. All you do is haul them to a metal recycler and collect cash. It's work. It would take some gas. But I'd bet if you hustled you could bring in more than $300 a day. Might be a nice way to put away a little money to start an online business. Who knows, you might end up with a few trucks and pull in a couple grand a day.
You could put up a site of your own saying you hauled away appliances, no charge. Of course, you could do that on Craig's List too. Happy New Year.
