They sell it and use the proceeds to pay for future operations, just like most non-profits that accept donations. The donator will be sent a receipt for the amount received at sale, and they can deduct that amount from income for a tax advantage. Most sales are at auction.
During WW II there was a great shortage of scrap metal; cars were driven forever, items were repaired and re-used, and the war industry had a huge appetite. Steel from blast furnaces filled in the gap of course.
When I worked in the foundry, every so often a big grain type truck full of scrap would make a delivery. All that old rusty junk was then melted down into brand new cast wheels and hand cart parts. Itās the cycle of life. I guess they donāt teach this in school anymore but it was just a known fact as a kid like where milk really came from. Of course it used to be fun to rummage through the scrap yards when they were closed.
I worked as a security guard at a foundry while in college. The scrap metals came in semitrailer sized dump trucks. The worst were the scrapped aluminum engine blocks from places like Briggs and Stratton. Talk about a racket when they dumped those.
The induction furnaces were massive in that place with crucibles about 8-10ft tall that would get hoisted from the furnace and poured into sand castings. Quite the showā¦
Same for the battery recycling plant I visited. Molten lead, plastic shred and skimming the acid mix. Danteās Inferno in there!
There are other nail products that are hard. Masonry nails have to be quite hard to penetrate bricks or mortar.
And ferrierās nails used to shoe horses are quite soft since they need to be either snapped off where they penetrate the hoof or turned over.
re: what happens when you donate a car to cartalk.
In our case it went to an auction and we got the write off for the auction sale price. Who bought it and where it went I have no clue but would think it was bought by someone for resale.
