I am new to this but it seems fun. I am used to taking in beer and soda cans for money but it isn't much money.

Last time I went to the recycling place I took in a bucket of old power supply transformers (iron) along with a trash bag of cans. I didn't know iron could be worth much. I made around 6$ which yeah not much but it was worth more than the cans.

Today I went in with a car full, old pots and pans, nails and hooks, pipes and so on and I made around 30$.

That made me wake up. I could actually make money in my town collecting this ****.

So here's the questions..

Do I have to take off the non metalic stuff first before taking it to the place?
Can I take in ordinary cans that are rinsed and cleaned that contained food like the kind you use a can opener on?

Are motors worth the same as power supply transformers?
Can you take in stuff that is not all metal? Like TV parts (the picture tube yoke) that is copper wire but surrounded by plastic?

That's only the beginning.

Is there any good documents or tutorials that you can recommend me that will teach me how to do this and make the most bang for the buck?

After this second time scrapping I found this is fun, it's like treasure collecting.
BTW I am not new to destroying electronics for metal.

I don't know anyone IRL that can teach me this stuff. Luckily my town has only a few people scrapping metal. So I have a good chance to make some dough and have fun doing it.

Thanks a ton. Thanks.
