Hi! :) I can think of the following reasons for recycling ferrous metals: 1. Iron ore is a limited resource and is bound to run out. 2. It takes a lot more effort and energy to make steel from scratch rather than from recyclable materials. 3. It sure avoids littering the environment with all those rotting...

Hi! :) Are there any specific machinery that can be used to recycle steel at the community or city level. All I see here are industrial-sized steel producing plants. A smaller system could boost recycling at the grass-roots level. Thanks. :)

I have a DVD player now, it replaced my old CD player. That CD player I sold to a junk shop. I understand they're gonna gut it of metals like copper, aluminum, and steel and turn the rest over to a landfill.
