I did some work for a steel mill in El Paso and got to watch them make rebar. They dumped crushed cars into the furnace, then lowered 3 huge carbon electrodes into it. After a lot of arcing and smoke, the mix melted. Then they used a long pipe to pump oxygen into it to heat it further and drive out the excess carbon. They had materials on hand to add to batches of steel they used for other purposes, but the rebar was made from whatever ended up in that pot from the melted junk cars.
